High index lenses coordination
Web1.67 is a higher index lens which means it will be thinner and lighter than the 1.60. Polycarbonate would be a better option than the 1.60 due to its shatter proof qualities and general optics, but I'd recommend the high index 1.67. Make sure you hen an antireflective coating and scratch protection as well. -4. WebA lens is high-index when the refractive index exceeds that of plastic or glass, as are used in most traditional materials. The general range of refraction is around 1.53 to 1.74. When the refractive index is 1.7 or more, the lens is usually about 50% thinner than it’s glass or plastic counterpart would be.
