Lens Guide

Step #1: Consider Lens Designs for all of your changing environments... Work, Fun, and Sun!

Lens Designs


Unlike traditional lenses, HD lenses are manufactured using digital computer technology and diamond-cutting tools that allow the lenses’ surface to be customized to an individual’s eyes. High-definition lenses can deliver this unprecedented level of customized vision correction because the lenses are engineered based on a digital scan of the eyes. The resulting, customized vision correction improves unique vision problem areas and providers wearers with superior clarity, and sharper, brighter eyesight, whether they are nearsighted, farsighted, or have a mild astigmatism. The lenses are also thin and light, making them ideal for long wear, even with the strongest prescriptions. HD lenses are most common in progressive lenses, but they can also be made for single vision glasses.

Digital Progressive Lenses

Digital Single Vision Lenses


Single Vision Lenses are prescribed if you need correction for one field of vision and have the same optical focal point or correction over the entire area of the lens.

  • Distance Viewing
  • Intermediate (Computer or for viewing items around arms length away from you)
  • Near Vision (Reading or for viewing items up close)

If your prescription indicates both a distance and a near power it is important to specify which of the three above options you require. Unless otherwise noted, we will assume the single vision lenses are to correct distance vision.

More Info


Bifocal Lenses are prescribed if you need correction for two fields of vision and a line or “Segment” separates the two focal points.

  • The upper part of the lens is generally used for distance vision, while the lower part is used for near vision.
  • Occupational bifocals can be specifically designed with the Intermediate or “computer” distance in the upper part of the lens and the “Near” or reading power in the lower segment.
  • Bifocal lens design offer a full field of view in the upper portion and either 28 or 35 millimeter width for the lower portion.
  • Unless otherwise specified in the notes section of your order we will assume the bifocal will be to correct distance and near vision.

More Info


Trifocal lenses are similar to bifocal lenses, except that there are three focal areas instead of two. The top portion of the lens is used for distance viewing, the middle is used for intermediate (commonly referred to as computer distance) and the lower portion is used for near or reading correction.

  • Trifocals are available in two common segment widths:
    • 7x28mm are the most common with the height of the intermediate portion of the lens at 7mm high and the width of the segment at 28mm.
    • 8x38mm are made with a slightly larger segment for deeper intermediate and wider reading segments.

Trifocal Lenses are excellent for patients that are currently wearing this design or are unable to adapt to a progressive lens design.

More Info


Occupational lenses provide some unique and exciting options for prescription lens wearers!  Below are some common options to consider and we welcome questions/consultations!


  • Adjust the reading segment width
  • Adjust the position of the reading segment
  • Double D Bifocal with added reading segment at the top of the lens


  • Adjust the intermediate/near segment width
  • Adjust the position of the segments


  • Desktop Progressive - Removes distance zone to increase intermediate & near zones
  • WorkSpace Progressive - Minimal distance zone to increase intermediate & near zones
  • Driving Progressive - Increases distance zone with smaller intermediate & near zones
  • Active LifeStyle Progressive - Improved peripheral & depth perception
  • Wrap Progressive - Improved peripheral distortions

Step #2: Select Lens Material to compliment your prescription powers and intended use...

We recommend Trivex and Polycarbonate plastic materials because of their inherent impact resistance.

Lens Materials


CR-39 Standard Plastic Lenses suitable for general purpose use.  These lenses offer outstanding optical quality and durability.  All of our lenses are manufactured according to ANSI Standards and include a Scratch Resistant Coating.

  • Lens Design Options:
    • Single Vision
    • Bifocal
    • Progressive
  • Lens Treatment Options:
    • Anti-Reflective Coating
    • Polarized Sun Lenses with or without Mirror Coating
    • Transition/Photochromatic Technology
  • Recommended for:
    • Prescriptions with Sphere values from Plano to +/- 3.00.

More Info


Trivex and Polycarbonate lenses are a thin and lightweight material, that is very resistant to impact.  These lenses block 100% of the harmful UV rays and include a Scratch Resistant Coating.  Polycarbonate is commonly referred to as “Featherweight”, “Lightweight”, and/or “Ultralight” Lenses.

  • Lens Design Options:
    • Single Vision
    • Bifocal
    • Progressive
  • Lens Treatment Options:
    • Anti-Reflective Coating
    • Polarized Sun Lenses with or without Mirror Coating
    • Transition/Photochromatic Technology
  • Recommended for:
    • Active Adults
    • ALL Children
    • Industrial Safety
    • Rimless Glasses
    • Sporting Activities
    • Plano +/- 4.00 

More Info


Mid-index lenses are slimmer and lighter than standard plastic types. Slightly stronger prescriptions for farsightedness typically require a thicker lens. Mid-index lenses minimize thickness in these prescriptions and are generally more affordable than high-index plastic materials.

High-index lenses are typically more expensive than standard plastic and mid-index varieties, but offer a wider choice of frames for people with stronger prescriptions, since the lenses are not bulky. Wearers benefit from a crisp, clear field of vision and comfort, even during prolonged use. When treated with a no-glare coating, high-index lenses sharpen sight considerably—especially at night.

  • Lens Design Options:
    • Single Vision
    • Bifocal
    • Progressive
  • Lens Treatment Options:
    • Anti-Reflective Coating
    • Polarized Sun Lenses with or without Mirror Coating
    • Transition/Photochromatic Technology
  • Recommended for:
    • +/- 4.00 and Up

Step #3: Lens Enhancements allow you to customize your perfect lenses...

Reduce lens reflections, improve scratch resistance, block blue light and reduce fog...

Lens Enhancements


Eliminates surface reflections on the lenses from artificial light sources such as headlights, computers, and fluorescent lights.

More Info


Top layer with fog repellence properties activated by Optifog Activator Cloth once a week or more frequently depending on needs..

Result : long-lasting fog free vision

Optifog benefits from Crizal latest innovations: glare reduction, dust repellence, scratch resistance, UV protection.

Result : clarity of vision and eye protection.

(Industrial Safety, Kitchens & Sports, etc...)

More Info


Sadly we have not found a 100% scratch proof lens, however, the good news is that all of our lenses include a manufacturer's standard scratch resistant coating.

If you are hard on your lenses you can add a "Hard Coat" for extra protection.

Proper cleaning and some TLC will prolong the life of your lenses 🙂

Step #4: Color provides fashion and protection!


Lens Colors

Mirror Lenses

Sunwear paired with mirror coatings blocks additional sunlight and reduces harsh glare by 10-15% with a solid mirror, and by 5-8% with a flash mirror. The added reflective properties of sunwear with mirror coatings add to the comfort of anyone suffering from outdoor light sensitivity.

Mirrors can be applied in several styles:

  • Solid or Flash
  • Gradients
  • Double Gradients
  • Clear Mirrors

More Info

Polarized Lenses

Polarized lenses are coated with a special chemical film that helps reduce glare. This allows the sunglasses to virtually eliminate bright light from reflective surfaces such as:

  • Water
  • Snow
  • Pavement
  • Sand
  • Metal

By neutralizing glare, polarized lenses help you see objects more clearly, and also help reduce the harmful effects of UV light.

More Info

Tinted Lenses

Tints, or filters, enhance your eyewear’s effectiveness in different lighting conditions.

Brown / Amber / Copper:

  • Sharpen contrast and reduce glare by filtering out blue light

Grey / Green-Grey:

  • Improve contrast, visibility, and depth perception with truer colors

Yellow / Rose:

  • Yellow-tinted lenses neutralize blue light which sharpen sight in low-light conditions
  • Red tints enhance color contrast and may improve visibility while driving
