Optic Topic by Steven A. Queenan at Regional Eye Optical – Week of January 6, 2019
For those who have a strong lens prescription, “high-index” eyeglass lenses are an especially good option. These lenses are thinner and lighter than conventional lenses and are significantly more comfortable and attractive.
For instance, a nearsighted individual needs a corrective lens that is thin in the middle and thicker at the edge. The stronger the prescription is, the thicker the periphery of the lens is expected to be. However, because high-index lenses bend light much more efficiently than ordinary lenses, less lens material is needed. As a result, high-index lenses have a smaller profile and weigh less.
High-index lenses with an aspheric design reduce the magnified “bug-eye” effect that often comes with conventional lenses in strong farsighted prescriptions. High-index lenses pair beautifully with rimless frames that leave the edges of the lenses completely exposed.
Most of today’s popular lens designs and features including progressive lenses and photochromic lenses, are available in high-index materials. But there are exceptions, so ask your eye doctor or optician for details.
