III. 1.67 High index lens:
- What are 1.67 high index lenses?
1.67 high-index lenses are made from materials---MR-7(imported from Korea), that allow optical lenses to be made ultra thin and ultralight-weight by bending light more efficiently.
- 1.67 high index lens technology
Thinner and lighter high-index lens materials have made the world of eyeglasses very different.
- What are 1.67 high-index lenses?
Made with dense materials with lots of light-bending power, they are be much thinner, flatter and more lightweight than standard lenses.
- How do they work?
Glasses correct your vision by bending the light that passes through to your eyes. The stronger your prescription, the more the light needs to bend. This generally means a thick lens, but not with a high index lens that bends light through less thickness.
- What are 1.67 high index lenses benefits?
A thinner, flatter high-index lens provides the same strength of correction as a thicker standard lens. That means people who are very short-sighted can avoid extra-thick lenses that make their eyes look unnaturally large; long-sighted people can avoid lenses that make their eyes look exceptionally small.
