What Do I Need to Know About Buying High Index Lenses?

Do you sometimes wish your high prescription glasses weren’t so thick? The good news is: they don’t have to be.

What to Know About Buying High Index Lenses

What Do I Need to Know About Buying High Index LensesIt used to be that thick lenses were simply the curse of having a strong prescription. Deeply-cut curves were required in order to bend light to the necessary degree, and that meant thick glass or plastic lenses. This led to excessive weight, eye magnification, and limited choice in framewear.

High index lenses are made from a composite material that bends light more effectively and efficiently than regular lenses. Therefore the necessary curves can be more shallow than before, resulting in thinner, lighter lenses that still provide the proper light-bending effect that forms your prescription.

High index lenses are available in several index ratings, in both glass and plastic, which will determine the overall thickness of your lenses. The higher your index rating, however, the higher the cost. The material also becomes more brittle and fragile as the index rating goes higher, so weighing the benefits and drawbacks of high index glasses is very much a personal decision.
