Lens and Lens Treatment Options Galore!


Conventional Plastic

Hard resin plastic lenses are half the weight of glass lenses, and can be tinted any color and intensity. Optional scracth coatings help protect their surface from wear and tear.

Ultra-Thin Plastic (Hi-index)

Modern technology has created hi-index plastic lenses which can be manufactured about one-half thinner than conventional lenses. In addition to being more attractive, they are much lighter in weight.

Polycarbonate Plastic

This type of plastic is the safest of all the lenses available. It is the preferred lens choice for children, active sports play or safety lenses. This type of lenses is also thinner and lighter than standard plastic lenses.

Photosensitive Lenses 

These lenses turn dark when you go outside, and clear again when you come inside avoiding the need for separate sunglasses.  They are available in both glass and lightweight plastic and in most bifocal styles.


The most scratch resistant material and also the easiest to break. The disadvantage of glass lenses is its weight, generally twice that of hard resin lenses.  They however can offer very sharp vision. 




Lenses with one focal power. Individuals with presbyopia (decreased accommodation) may need several pairs for the various viewing distances needed.


Lenses with two focal powers (or distances) in the same lens. This allows two different distances to be clear in the same pair of glasses, usually far vision and near vision.


Lenses with three focal powers or distances. This allows three different distances to be clear in the same pair of glasses, one for far vision, one for near, and one focus for the intermediate zone.

Progressive (No Line Bifocals)

These lenses provide all the benefits of bifocals or trifocals, but add the convenience of continuously clear vision from distance to near. Progressive lenses have the cosmetic advantage of being “invisible”.

Occupational Lenses

Many occupations have visual demands at special distances or locations, such as electricians and pilots seeing overhead.  Special occupational lenses are available to provide the best vision for every particular need.

Computer Lenses

There are a variety of options available to make computers use as natural and comfortable as possible. Frequently an individual will benefit most from a special pair of glasses designed specifically for computer use.

Sports Glasses

Special visual requirements for sports can include the need for eye safety, sun and glare protection.  Special frames and lenses are available to insure your optimum and safest vision for all sporting activities.



Scratch Protection Coating

Lightweight plastic lenses are more easily scratched than glass lenses. Special protective coatings have been developed to help reduce scratching from normal day-to-day wear and tear.

UV Protection

Ultraviolet rays in sunlight pose potential harm to the eyes. Special treatments are available which blocks this hazardous UV light.  These are avauilable in both clear and sunglass lenses.

Antireflection Coating

Special coatings are used to eliminate reflections much like camera lens coatings. This type of coating dramatically improves night vision, driving, and helps reduce eyestrain or fatigue from the glare of computer work.


Darker tints can protect your eyes form the sun. Lighter tints are for cosmetic purposes, and can reduce glare from overhead lights.

Sunglass Lenses

These are lenses designed to protect you against bright sunlight and UV exposure. These lenses are available in gray, green, brown, blue-blocker as well as many other colors.

Sunglass Clip-ons

High quality non-prescription sunglass lenses that protect you against UV light can also be clipped right on to your existing frames.  New designs provide the highest eye safety as well as a secure fit and great appearance.

Polarized Lenses

These are very special laminated lenses that reduces glare off any reflective surface. They are very helpful to maximize your vision for water sports, driving, snow skiing, and many other outdoor activities.
