Lens selection
Ordering prescription sunglasses?

The added lenses will not be the same color or tint as the original factory sun lenses. A sun option must be selected, or the lenses added will be clear.

The easy 4-step lens ordering tool will help guide you to make the best lens selection for your order. Each step groups the different configurations with helpful descriptions as well as the availability and price that may change based on the prior step option selected.

Lenses are highly configurable devices with various available and restricted options. The lenses shown in this step may be restricted based on the frame type selected (i.e., Rimless glasses). The lens selection is generally based on the preferences, budget, and needs of the wearer. 

 

Select your lenses in 4 easy steps:

Select Vision Type

Single-vision, multifocal or non-prescription

Choose whether the lens is single vision (distance or near), progressives, bifocals, trifocals, or non-prescription.

Lens type guide
Select Sun Option

Clear, sun-sensitive, or polarized sun

The sun option brand names may be exclusive only to certain lens brands. However, many of these sun features may function similarly across brands. Select a sun option based on brand familiarity or functionality.

Select "Clear" if no sun option is desired, or to add standard solid or gradient custom tinting in the following step. (only available for tintable materials)

Compare sun options
Select Lens Material

Weight, thickness & strength (and clarity)

The lens material controls how thick and heavy the lens will be; some materials offer impact resistance and include UV and scratch protection. For strong prescriptions, when thinner lenses are selected, the aberration value should be considered as this relates to the amount of light that passes through the lens material, making the vision more true to normal or less distorted.

Select Brand & Design

Brands, designs, and coating options

Brand:

The brand is typically the customer's preference to meet certain expectations with comfort or familiarity. The brand also has its own exclusive options and coatings, which may be essential when ordering lenses.
 

Coating options:

The coating options may vary based on the lens brand but may offer similar functionality across the brands. Some lenses may also be packaged with included coatings. If a specific coating brand is desired, the respective lens brand would need to be selected.
 

Series & Designs:

Each lens brand may label the lenses in certain designs with different series names. Some of these include designs or options like digital (freeform), blue-light, and anti-fatigue options that are generally available across various premium lens brands.

For progressive lenses, the lens series may also refer to the design of the vision corridors and adaptability for certain lifestyles. Some progressive lenses may emphasize distance, intermediate, or near vision more than others, which are more commonly worn every day.

For bifocal/trifocal lenses, the design focuses on the shape and size of the reading window (i.e. Flat-top 28, FT-35)

Prescription details
Only for prescription lenses

Skip this step if ordering plano non-prescription lenses.

The final step for ordering lenses requires the customer to provide a prescription for the lens order. Although some online stores may not require a valid prescription to place an order, we go that extra step to ensure our customers receive the correct lenses their doctor has intended. Therefore, aside from prescription readers, a valid eyeglass prescription is required to order prescription lenses. The information requested is used to verify the prescription in the order with the doctor's office.
 

1. Patient Verification

The patient and verification option is required for the prescription order.

 

Patient Example

Patient Name

The patient's full name must be the same as written on the prescription. This is used to verify the patient's order with the prescription.

 

Verification Option

We offer multiple ways to provide prescription verification (Email, Text/SMS, Fax), or you can provide your doctor's information, and we'll call to get it. Alternatively, a prescription on file may be used without requiring additional verification.

Verification options

2. Prescription Details

The prescription details may be left blank; our verification staff will do the rest.

 

Rx Example

Prescription Parameters

Providing the prescription parameters is not required. However, it may be entered online if desired. Our verification staff will input the information or make any necessary corrections upon manually reviewing the prescription.

All parameters supported

 

PD Measurement

The pupillary distance or the distance between the pupils may be provided as a single number (binocular) or two separate numbers for each eye (monocular).

Note: Many phone apps measure the PD. We suggest taking multiple readings for consistency.

Measuring my PD

Readers only

Instead of providing an eyeglass prescription, select the "Readers Only" option if ordering readers. A valid prescription or verification is not required.

 

Readers Example

Reading Strength

Select the reading power desired for the readers.

 

Use the additional comments section to provide any information to be reviewed by the verification department.

The following step will be the shopping cart page, where the customer may proceed to the checkout screen to submit their order.

Lens Recommendations
Lens thickness chart
Considerations:
  • Choosing a smaller frame may reduce lens mass & thickness.
  • Plastic frames are effective in hiding thicker-edged lenses.

Lens thickness depends on the index, with higher indexes offering thinner, flatter, and lighter lenses, ideal for stronger prescriptions. Consider the recommended prescription ranges for each index to ensure suitability. Thicker lenses, common in stronger prescriptions, can be heavier and cause a "coke-bottle" effect, impacting vision and appearance. Plus (+) prescriptions may have a thicker center, while minus (-) prescriptions have a thinner center, influenced by the lens index. Choose the right index for your prescription to optimize thickness and visual aesthetics.

CYL: 0.00 to 4.00
 

Aberration (Abbe) Values:

The ABBE or Aberration value describes the amount of chromatic aberration of an ophthalmic lens. The higher the number, the less amount of aberration and better visual performance and peripheral vision. Standard CR-39 plastic has the highest ABBE value and offers the best visual performance. Meanwhile, the Polycarbonate material has the lowest ABBE value and offers the least. The ABBE values are fairly similar or the same across the different lens brands offered.

 

1 Thinner up to the advertised amount when compared to standard plastic CR-39 (1.50) index lenses. The maximum thinness amount may vary based on prescription strength.

2 Lenses outside of the recommended range (plus or minus powers) may be subject to custom surfacing delays and additional costs.

Back to Top
Frame restrictions

Options and eligibility for adding prescription lenses to ophthalmic glasses may vary based on the frame type. The following displays the different types of frames and what to consider when ordering lenses.

 

Prescription frame eligibility:

  • Any prescription
  • Lighter prescriptions only
  • Uneligible

Standard Ophthalmic Frame

Plastic

Plastic full-rimmed frames are well-suited for stronger prescriptions that may necessitate thicker-edged lenses, as they effectively conceal the lens thickness. This not only enhances the cosmetic appearance but also provides a more aesthetically pleasing result compared to other frame materials.

Metal Ophthalmic Frame

Metal

Opting for thin-edged lenses is advisable, particularly with metal frames, as metal frames tend to expose the lens edge more than plastic frames. Thin edges contribute to a sleeker and more refined appearance in such cases.

Rimless nylor opthalmic frame

Semi-Rim

Semi-rim glasses, also known as nylor or half-rim frames, necessitate lens edge grooving to accommodate the rim notch and wire for stability and reinforcement. Adequate space is crucial to facilitate wire grooving without compromising the thickness of the lens edge. Opting for durable materials like polycarbonate or Trivex is recommended to enhance durability and minimize chipping.
Given that a portion of the lens is exposed without the protection of a full rim, there is an increased susceptibility to chipping. Therefore, handling these lenses with extra care is essential. Additionally, implementing edge polishing can contribute to improved cosmetic appearance and overall lens aesthetics.

Full Rimless opthalmic frame

Rimless

Lightweight rimless glasses feature lenses that are drilled and mounted onto the nosepiece and hinge. To ensure durability, it is essential to use lenses made of Polycarbonate, Trivex, or Hi-Index (1.67+). Please note that an additional fee for the drilling and mounting process will be applied when placing a lens order.
Given that lenses in rimless glasses are fully exposed, they are more susceptible to chipping and damage. Therefore, it is crucial to handle them with extra care. In cases where screw-in mounting is used, occasional tightening may be necessary if they become loose. Additionally, the application of edge polishing can enhance the overall cosmetic appearance of these glasses.

Flat base sunglass frame

Flat Base

Flat-based sunglasses, characterized by a base curve of 4 (the lowest), are well-suited for individuals with all prescription strengths, including stronger prescriptions. The flatter lens design minimizes distortion and effectively reduces the "coke-bottle" effect often associated with stronger prescriptions. This frame type is particularly advantageous when paired with aspheric lenses, offering an ideal combination for clear vision and enhanced aesthetics.

Mid Wrap-around Frame

Mid Base (Wrap-Around)

Mid-wrap frames, featuring a base curve of 6, exhibit a slightly greater curvature compared to standard frames with a base curve of 4. These mid-wrap-around frames are capable of accommodating prescriptions up to ± 4.00. The increased curvature is designed to provide a subtle wrap-around effect, offering both style and support for a range of prescriptions. The maximum prescription strength is contingent on the pupillary distance PD measurement, emphasizing the importance of accurate measurements for optimal lens fitting in these frames.

Steep Wrap-around Frame

Steep Base (Wrap-Around)

Steep wrap-around frames, characterized by a base curve of 8+, are specifically designed for a pronounced wrap-around effect. However, these frames are suitable only for light prescriptions, supporting strengths up to ± 2.00. The maximum prescription strength is contingent on the pupillary distance PD measurement, emphasizing the importance of accurate measurements for optimal lens fitting in these frames.

Oversized Glasses

Oversized

The maximum width for blank lenses is 70 millimeters, meaning frames larger than 65 millimeters cannot accommodate additional lenses; this may be based on the PD measurement. For thick-edged (minus) lenses, opting for a thinner design is advised, as wider lenses tend to be thicker. Therefore, oversized frames are more suitable for lighter prescriptions, up to ± 2.00, ensuring optimal aesthetics and performance.

Sun shields

Shields

As of now, single or double-lensed shields are not currently eligible for prescription lenses. Blank prescription lenses are typically available conventionally in a round shape with a maximum width of 70 millimeters per lens/eye. Shields, due to their specific design, are not suitable for conventional prescription lenses. Some shield manufacturers may provide adapters or inserts that can fit behind the shield, but in such cases, lenses must be added separately to the insert or adapter.

Goggles

Goggles

Goggles are not eligible for prescription lenses at this time. Please see the Shields section for further details.

High-performance Eyewear

Active Sports

High-performance or active sports styles are currently not eligible for prescription lenses due to the unconventional nature of the frame and the unique method by which the lens is attached and reinforced to the frame. These frames are not designed to support the standard format of traditional prescription lenses. For additional information, please refer to the Shields section.

Lens Designs
Digital / Freeform

Digital (FreeForm) lenses are made digitally, whereas traditional lenses are conventionally ground. Digital lenses aim to optimize visual performance by reducing distortions, correcting aberrations, and offering a more natural and comfortable viewing experience.

Digital Freeform lenses
 

Digital / Freeform key features:

  • Digital lenses allow for complex prescriptions and individualized lens designs. This customization can address optical aberrations, improve peripheral vision, and provide a wider and clearer field of view.
  • Digital lenses can be designed to be flatter and thinner, making them more aesthetically pleasing and comfortable, especially for individuals with higher prescriptions.
  • Digital lenses are particularly effective for progressive lenses, where a smooth transition between distance, intermediate, and near vision is crucial.
 

Digital lenses may be made digitally on both the back and front sides of the lens or only the back side of the lens. Both front and backside digital lenses are referred to as "Freeform" lenses.

 

FreeForm Digital (Both sides)

FreeForm digital lenses apply digital technology to both the front and back surfaces of the lens and offer a higher degree of customization than standard digital backside-only lenses. 

Digital Backside only:

The digital technology is applied to the back surface of the lens, which is the side facing the eye. The front surface of the lens remains conventionally ground.

Back to Top
Aspheric
Considerations

It is suggested to add Anti-glare when ordering aspheric lenses to help reduce distortion.

Most lenses are Spheric with a standard conventional design with curvature based on the prescription strength. Aspheric lenses are a type of eyeglass lens designed with varying curvature to achieve a flatter and thinner profile, minimizing the "bug-eye" or "coke-bottle" effect associated with strong prescriptions. These lenses enhance aesthetics, provide improved peripheral vision, reduce image distortion, and offer a lighter weight than traditional spherical lenses. Aspheric lenses are particularly beneficial for individuals with higher prescriptions or astigmatism, providing a more natural appearance and comfortable visual experience. They are functional and contribute to a cosmetically appealing design for eyeglasses.
 

Key features:

  • Reduced lens thickness
  • Improved aesthetics
  • Enhanced peripheral vision
  • Minimized image distortion
  • Lighter weight

Reading boost

Lenses with Reading Boost, also known as reading enhancement, anti-fatigue, or advanced single-vision lenses, provide additional magnification at the lower portion of the lens for near-vision tasks, such as reading or other close-up activities. These lenses benefit individuals who may experience difficulty with small print or fine details as they age, a condition often associated with presbyopia.

Reading boost lenses are similar to mild progressive lenses and are generally intended for adults under 50 who may not need all that a progressive lens offers. And also someone who would like to enjoy lower prices than what your ordinary progressive lens can cost.

Reading boost anti-fatigue lenses

Reading boost key features:

  • Magnification Near Vision
  • No visible lines on the lens
  • For mild reading powers
  • Enhanced Reading Comfort
  • Designed for Pre-presbyopia
  • Lower cost than progressive lenses
 

Boost power availability:

The powers available for reading boost may vary based on the lens brand.

Bifocals & trifocals

Bifocal & trifocal lenses come in various designs to address different vision needs. The lower part for near vision has a flat or straight top line, creating a visible segment in the lens. Trifocals and Occupational lenses include an additional segment for intermediate vision. Choosing the right design depends on individual preferences and lifestyle.

Bifocal flattop 28

Flattop 28 (FT-28) Bifocals

The flat top (FT) or straight top (ST) bifocal near-vision window is 28 millimeters wide across the top. This is the most common bifocal type.

Bifocal flattop 35

Flat top 35 (FT-35) Bifocals

The flat top (FT) or straight top (ST) bifocal near-vision window is 35 millimeters wide across the top for a broader field of near vision.

Executive bifocal

Executive Bifocals

The flattop bifocal near-vision window across the entire lens bottom is for the broadest field of near vision. This makes them suitable for tasks that require extensive near vision, like reading or computer work.

Round seg 24 bifocal

Round seg 24 (RS-24) Bifocals

The near-vision segment is a round shape, providing a smoother transition between the distance and near prescriptions. The RS24 has a bifocal segment of 24 millimeters wide.

Occupational bifocals

Occupational "Carpenters"

The Occupational lens is designed for specific tasks or occupations, with customized prescriptions for intermediate and near vision, often without a visible line.

7x28 trifocals

Flat top (FT) 7x28 Trifocals

The Flat top (FT) 7x28 offers a magnification power of 7 times for close-up vision and 28-millimeter width for the intermediate and near vision segments. Trifocal lenses typically have three distinct prescription zones separated by visible lines – the upper part for distance vision, the middle for intermediate vision, and the lower segment for close-up tasks. This design is beneficial for individuals with presbyopia, addressing the need for clear vision at various distances.

Progressives
Progressive lens features
Better progressive lenses have a higher price tag

Higher-quality progressive lenses generally have a higher price tag and provide a better vision experience.

Higher-quality progressive lenses offer solutions optimized to suit the individual's lifestyle, significantly enhancing the ease of using progressive lenses.

 

Key features include:

  • Larger/broader reading corridor
  • More flexibility and eye movement (less neck movement)
  • Smooth transition between distance, intermediate, and near
  • Less off-balance ("Seasick") feeling
  • Less peripheral distortion in soft (out of focus) focus areas or on the outer portion of the lens.
  • Digital / Freeform designs optimized for the individual.


Aside from these features, progressive lenses have the same features as any other lens concerning a lens's core features like the material (weight, thickness, and strength), sun option, and coatings that may also improve the visual experience. Please refer to our extensive lens help guide for further details about these other features. 


Progressive Lens Manufacturer resources and websites:

More information regarding the different progressive lens brands and designs may be found directly on the manufacturer's websites below.

Back to Top
Progressive lens designs

Each individual progressive lens is available in either a Standard or Short corridor design or "corridor."
 

Progressive Lenses

Lens corridor

A lens corridor, also known as the "corridor length" or "progressive corridor," refers to the middle portion of a progressive lens where the power changes gradually from the distance prescription to the reading or near prescription.


The corridor is the area that allows for a seamless transition between different prescriptions, accommodating the wearer's needs for clear vision at various distances. The length and width of the lens corridor can vary depending on the design of the progressive lens. A longer corridor generally provides a larger area for intermediate vision, making it suitable for tasks such as computer work. On the other hand, a shorter corridor might be preferred for smaller frames or for individuals who prioritize a larger reading zone.
 

Standard corridor

The standard corridor offers a larger corridor and a more seamless transition between the different vision areas of the lens. This makes the lens more optimized for the wearer by offering easier use and adaptability.
 

Short corridor

The shorter corridor is for smaller frames that generally have less than a 30-millimeter lens height. A short corridor will have a shorter corridor for the progressive transition, which may be less optimized. Therefore, opting for a higher-quality progressive lens is advisable to improve the corridor transition in a short corridor lens. A short corridor is suitable for individuals who prefer smaller eyeglass frames.
 

Variable design corridor

Freeform digital lenses are only available as variable design corridors. Variable design corridors prioritize the quality of the distance and intermediate area by optimizing the lens based on the specifications of the Rx, frame measurements, and seg height. A front and backside digital lens (Freeform) must be selected to get a variable design corridor. Otherwise, non-freeform lenses will be fixed-design corridors, which means there's more focus on the reading location in relationship to the pupil, much like a traditional flat-top lens. 

 
Back to Top
Lens quality grades

Lens quality grades were created to help identify the different quality of lenses across various lens brands. The grades only apply to progressive lenses at this time.

Progressive Lens Quality Grades

Standard
 
Traditional (legacy) progressive lens designs or value brands are generally introduction-level progressives and the most affordable.

Advanced
 
The Advanced-grade mostly includes digital progressive lens options that are typically considered better than standard traditional options.

Premium
 
The Premium grade mostly includes all the freeform digital progressive lens options which are considered better and more customizable than the Advanced options.

Elite
 
The most high-end progressive lens options available typically include freeform digital design and other qualities that make them classified in the highest tier of progressive lens options available with the highest level of customization available. These lenses are known to offer the best lens experience and adaptability.
Back to Top
Seg height measurement
The seg height (segment height) refers to the vertical distance (in millimeters) from the bottom of the lens (or eyewear frame) to the top of the near-vision segment in bifocal or progressive lenses. This measurement is necessary for multifocal lenses, as it determines the position where the wearer will naturally look through the lens to see clearly for tasks like reading or close-up work.

Seg height measurement example

Bifocal Seg Height

For Bifocals, the seg height is the measurement from the lower edge to the top of the reading segment. The seg height for bifocal lenses is typically determined by dotting the lens at the lower eyelid of the wearer while wearing the frame. Bifocal seg height measurements usually range between 12 to 16 millimeters.
 

Progressive Seg Height

For Progressive lenses, the seg height is measured from the lower edge of the lens to the middle of the pupil. The seg height for progressive lenses is typically determined by dotting the lens at the middle of the pupil of the wearer while wearing the frame. This measurement helps align the various zones (distance, intermediate, and near vision) properly to ensure comfort and functionality for the wearer. Progressive seg height measurements typically range between 18 to 23 millimeters.

While measuring the frame's seg height may help ensure optimal vision and comfort, this measurement isn't required for placing orders. If available, the customer may provide their own seg height measurement for a progressive lens during the lens order on the prescription form. Otherwise, our office will use our in-house formula, which is accurate in most cases.
Back to Top
In-house fitting formula

Our lab has over 40 years of optical experience crafting bifocal, trifocal, and progressive lenses. We use a proprietary fitting formula that is calculated according to the patient and the frame. If you would like to use a custom Seg Height Measurement for the progressive lenses, it may be provided during the lens order when providing a prescription (step 3).

Sun-sensitive / Photochromic

Sun-sensitive (or photochromic) lenses, intended for part-time sunglass use, are clear indoors and get darker under the sun.  Exposing the lens directly to the sun's UV rays turns ordinary lenses into sun lenses when they are needed the most. A variety of high-quality premium photochromic lens options are available and packaged with the lens. Sun-sensitive coatings are usually only available in neutral colors like grey, brown, or green, with select brands offering other shades like blue and purple.

 
Types of sun-sensitive coatings:

Certain photochromic coating brands may offer darker levels, faster activation times, and even include polarization.

  • Standard sun-sensitive coatings are usually clear indoors and reach about 50% maximum darkness when activated.
  • Fast-acting sun-sensitive coatings are usually the same darkness as standard, with faster tint activation times. Usually, it takes around 30 seconds of sun exposure instead of the common 60-second activation time.
  • Extra/dark sun-sensitive coatings are usually 5-10% tinted indoors and reach 60-70% maximum darkness when activated. These are generally darker behind the windshield.
  • Polarized photochromic offers the best of both worlds and goes from clear to around 70% darkness.

Polarized
Please note:

Polarization reacts to glare differently than anti-glare coating. While anti-glare coating helps reduce off the lens, polarization helps reduce glare off surfaces and objects being viewed. Combine your lens with both for the ultimate no glare sun lens.

Polarized lenses are advanced full-time dark sunglass lenses that reduce glare off surfaces & objects and improve visual acuity, as opposed to traditional color tinting. These lenses are great for fishing, skiing, and outdoor activities.

 
Polarized lens options:

UV protection
100% UVA/UVB protection helps block UV light from sun rays. UV coating is included with all lens materials except for plastic, where it may be added for an extra cost. Many anti-glare coatings are bundled with UV protection so be sure to check out all of the options available.

Scratch protection
The scratch guard is a hard resin scratch resistance hardcoat that helps prevent minor knicks and scratches. However, does not make the lenses scratch proof. To receive a scratch warranty with your lenses, consider adding anti-glare coating which includes a one-time scratch redo within a minimum of a year. Scratch guard is included with all lens materials except for plastic, where it may be added for an extra cost. Many anti-glare coatings are bundled with scratch protection so be sure to check out all of the options available.

Blue-light protection

Blue-light protection coating filters out blue light emitted from computer screens, smartphones, tablets, and television screens while letting the beneficial light pass through. Long-term exposure to blue light can cause eye strain and fatigue, which harms the eyes.

Blue-light protection is packaged with many lenses but is also available in additional coatings, with each level offering about 20% protection. Combine multiple levels of blue-light protection to receive the maximum protection against blue-light exposure.

Benefits of Anti-Glare coating:

Anti-Glare Coating Benefits
  • Less eye strain & fatigue
  • Improves cosmetic appearance
  • Reduces annoying lens glare
  • Reduce headlight glare
  • Reduces lens distortion (for aspheric & progressive lenses)
  • 1 year scratch warranty
Premium coatings also include:
  • Easy cleaning properties
  • Anti-water and anti-dust (hydrophobic)
  • Anti-oil and smudging (oleophobic)
  • Enhanced scratch durability
  • UV protection
  • Blue-light protection
  • 2 year extended scratch warranty
 

Hydrophobic & Oleophobic coatings:

Hydrophobic and oleophobic coatings enhance the performance and durability of anti-glare coatings by repelling water (hydrophobic) and resisting oil and fingerprints (oleophobic).

Oleophobic repels oils from the skin, such as fingerprints and smudges, making lens cleaning easier.

Hydrophobic coating repels water from the lens surface. It is especially beneficial in rainy or humid conditions, as water droplets are less likely to cling to the lens surface.
 

Premium Anti-Glare coating brands:

Crizal Anti-Glare Coating

Options and pricing may vary based on the lenses selected.

 
Anti-Glare hue colors:

Anti-Glare Coating Hue

Anti-glare coating leaves a slight hue on the lens that looks like a film or residue. The hue is intended by design and is used to help reduce the white glare on the lens. Some coatings, like select Duravision anti-glare coatings, leave a blue hue that may be preferred for cosmetic reasons.

Lens edge polish

Lens-edge polish improves the cosmetic appearance of the lens. However, a polished lens edge can also cause higher glare due to reflective light, which can sometimes be bothersome. This feature is usually added for thicker lenses, for rimless frames, or upon special request. There is no extra cost for lens-edge polishing.

Edge grooving

Lens-edge grooving is processed for semi-rimless, half-rimless or nylor frames. The lens stability is usually supported by a wire fitting inside of the edge groove. It is recommended to consider the lens should have a fair amount of edge thickness to support a stable grooving and preserve lens integrity. Polycarbonate or Trivex materials are recommended for durability. There is no extra cost for lens-edge grooving when lenses are ordered with semi-rimless frames.

Drilling & mounting

Lens drilling & mounting are for full rimless glasses. Lenses are precisely drilled to the manufacturer coordinations then mounted to the frame to ensure an accurate fitting. Lens options for full rimless glasses are limited to Polycarbonate, Trivex and Hi-Index 1.67 (or higher) materials only for durability reasons. Due to the fragile nature, it is recommended to handle these lenses with greater care than an ordinary pair of glasses. Moreover, further maintenance (tightening) may be needed from time to time. There is an extra cost for drilling & mounting that is usually applied to the lens order when ordering lenses with full rimless glasses.
