1.56 Blue Cut Photochromic Gray HMC Optical lenses

Short Description:

Lens is a transparent material with one or more curved surfaces made of optical materials such as glass or resin. After polishing, it is often assembled into glasses with a glass frame to correct the user’s vision and obtain a clear field of vision.

The thickness of the lens mainly depends on the refractive index and degree of the lens. Myopic lenses are thin in the center and thick around the edges, while hyperopic lenses are the opposite. Usually the higher the degree, the thicker the lens; The higher the refractive index, the thinner the lens

The main differences between blue light blocking lenses and ordinary lenses are as follows:

1. Different colors

Blue blocking lenses are light blue or yellowish; Normal lenses are transparent and have no color.

2. Different functions

Anti-blue light lens is a kind of lens that can prevent blue light from irritating the eyes. Special anti-blue light glasses can effectively isolate ultraviolet and radiation, and filter blue light, which is suitable for watching computer or TV, mobile phone and other electronic products. While ordinary eyes have no special effect, it is suitable for going out, writing or reading when wearing.

3. Different prices

Blue ray blocking lenses are usually more expensive than regular lenses.

Production Introduction

Smart color changing lens

Also known as "photosensitive lens", it is generally achieved by adding silver halide substance to the lens itself or spinning color changing film on the surface of the lens. The lens becomes dark under strong light and becomes transparent under indoor light. The color of the lens is automatically adjusted according to the intensity of light/ultraviolet.
