About understanding coated lenses

 Coating High Index Lenses Meaning is a new technology that uses optical film and vacuum to coat single or multilayer optical film of certain thickness, so that the lens can obtain some new and original excellent properties, so as to improve the reflective ability of the Gradient Tint Prescription Lenses, enhance or reduce the transmittance of the lens, and increase the transmittance of the lens to 98%.

The main film layers are dural, multilayer anti - reflective film, anti - fouling film and so on. The color of the coated Transition Lenses originally produced is green, mainly to distinguish it from the non-coated Eyeglasses Transition Lenses. In the 515nm part, the reflection is enhanced, about 2%, so that the contrast is achieved, and the reflection is green. This film is the most standard anti - reflective film, the best available and the oldest.
