Lens Types

Lens Material

Traditional Plastic (CR-39)

Used to fabricate single vision, bifocal, trifocal and no-lined bifocals or Progressive lenses.

High Index (1.67-1.74)

High index is a thinner plastic that does the same job as the traditional plastic but is lighter and cosmetically more desirable with higher prescriptions. This thinner plastic is used to fabricate single vision, bifocal/trifocal and no-line bifocal or Progressive lenses. High index lenses are classified by numbers (N-value). The higher the N-Value, the thinner and lighter the lens.

Polycarbonate (N-Value/ 1.5)

The first and most popular high index lens is polycarbonate. Polycarbonate was originally developed for fighter jet cockpits. It is very strong, very light, and resistant to scratches and breaking. Polycarbonate is McMillin Eyecare’s lens of choice for children, sports enthusiast and for safety glasses. We have a full stock of polycarbonate lenses such that in some cases we may be able to provide your glasses the same day as your exam.

Other High Index Lenses (N-Value 1.54-1.67)

These lenses are thinner and lighter than polycarbonate, but not as strong.

Glass Lenses

In the early days of vision correction, all lenses were made of glass. And while glass lenses do offer good optics, they are heavy, costly and can easily break thus potentially damaging the eye. It’s for these reasons that glass lenses are less frequently prescribed today.

Transitions Lenses

These lenses automatically adjust from clear to dark and every shade in between. When these lenses are exposed to sunlight, the photochromic molecules in the lens change structure. This reaction causes the lenses to darken and block harmful UV light from our eyes.
