Our Lenses

While not as flashy as the color or shape, the lenses of a pair of glasses are arguably the most important. DiscountGlasses.com offers Essilor lenses in four different options for both single vision and progressive prescriptions, ranging from standard plastic to light-adaptive Transitions®. Our detailed description of each lens—along with explanations of some key industry terms—will help you make the best decision in choosing the right one.

Our Lenses

Terms to know:

  • Lens Index: This indicates the thickness of the lens. The higher the index number, the thinner the lens.
  • Abbe value: The abbe value measures how widely the lens disperses different wavelengths. Ranging from 30 to 60, the higher the abbe value, the better the visual clarity.
