What are High Index Lenses, and why would you need them?
When you you have a high prescription it is often more comfortable, lighter, thinner and better looking to wear higher index lens.
This is because as the prescription gets stronger the outside of the lenses get thicker, whereas the prescription for most of us eyeglass wearers with average or even minimal correction is for nearsightedness --- which needs the center of the lenses to be thicker.
At Eyewear Insight we offer 3 levels of high index lenses.

What's Great About High-Index Lenses
- Much Thinner --- Because of their ability to bend light more efficiently, high-index lenses for nearsightedness have thinner edges than lenses with the same prescription power
- Much Lighter --- The thinner edges use less lens material, so the lenses are lighter.
- More Comfortable ---They are lighter therefore, more comfortable and less tiring!
