Lens Types & Materials

Basic Lens Types


Single vision lenses have the same power of correction across their whole surface. They can be used to correct “simple” vision conditions, such as myopia, hyperopia, and astigmatism, as well as “high correction” patients – people whose eyesight is very poor.



Bifocal lenses have a very distinct line dividing a reading area from distant viewing. They are designed to allow you to see objects either near or far by essentially com­bining two lenses into one. This older bifocal technology has been largely replaced by more desirable and attrac­tive progressive lens technology as detailed below.



Progressive lenses are “multi-focal” lenses where their focal power “progresses” from top to bottom. Progres­sive lenses or “no-line” bifocals offer a gradual transi­tion from distance to near vision without a visible line separating them. This means that instead of having only two different viewing zones (near and distant), like with bifocals, progressive lenses provide vision at all distances and provide more natural vision correction. Varilux® lenses are the preferred progressive lens on the market, providing the most natural vision at any distance and in any situation.



If you’re over 40 and having difficulty with your near vi­sion, you are likely experiencing presbyopia. Presbyopia, is a gradual change in the eye’s ability to focus and it is a common part of aging. The first solution many people try to combat presbyopia is a pair of reading glasses. While reading glasses are a low cost solution, a better solution is prescription lenses tailored to your specific vision needs. Choosing progressive lenses instead of readers eliminates the hassle of putting reading glasses on and taking them off frequently.

High Index Lenses

Hi-index lenses are thinner and lighter with more aesthetic appeal and greater comfort.


When it comes to impact resistance, polycarbon­ate lenses outperform hi-index lenses, offering12X more impact resistant power than standard plastic lenses. Polycarbonate lenses are a great option for children, teenagers, and active adults. They are 20% thinner & 30% lighter, making them more comfortable and more aesthetically pleasing.
