eyeglass prescription for short sight For example, if the lens power is approximately -2.00, it may be more suitable to opt for 1.56 index lenses. 10/2/2021 6/3/2017 Lenses with high indexes can be thinner and lighter than traditional plastic lenses. Compared with traditional lenses, highly index lenses can bend the light more efficiently, so they can be thinner while maintaining the same correction power. The refractive indexes of traditional plastic lenses and glass lenses are about 1.5 and 1.52 respectively. 15/9/2009 And that is the basic difference between 1.67 and 1.74 high index lenses: the latter is simply thinner, and lighter, than the former. Lenses with a refraction index of 1.7 or higher are at least 50 percent thinner than those with a regular index.

From there, if you have a prescription over -6.00 diopters, a 1.67 high index lens is a worthwhile upgrade.

Limited Option Lens AR Included Power Availability: SPH Range -2.00 to -8.00 CYL Range +2.00 to -2.00: Crizal AR Options Available Power Availability: SPH Range +8.00 to -12.00 Index of Refraction is the speed of light in a vacuum divided by the speed of light in a given material. The resulting number (1.5, 1.6, 1.67, 1.74) is referred to as the “index.” The higher the number, the more light is slowed down or bent.
