1.60 High Index Glass Lenses are a type of eyeglass lens that is thinner and lighter than standard glass lenses, suitable for mild to moderate prescriptions (around +/- 3.00 to +/- 5.75 diopters). They are a good choice for people who want a more comfortable, aesthetically pleasing look because the higher index of refraction means less material is needed, resulting in thinner and less bulky lenses.
