What are High Index Lenses?
A high index lens is a lens that has a higher “index” of refraction. The higher "index" of refraction has a greater ability to bend light rays to provide clear vision for people with stronger prescription glasses. In the past, strong prescriptions meant dealing with a thicker, heavier lens that produced a "coke bottle" appearance. Dealing with these unwanted effects from having a strong presciption are a thing of the past.
High index lenses are manufactured to be thinner, lighter, and more visually appealing. This type of lens is a preferred option for people who have strong prescriptions. When compared to ordinary lenses, high index lens are able to use less material while bending the light rays more to correct a strong presciption.
For better comfort, clearer vision, and improved cosmetic appeal, people with strong prescriptions now have a lens that will allow for all this! For more information about high index lenses call us at Avery Ranch Eye Care!
