Factory Cheap Photochromic Prescription Lenses - 1.56 FSV Photo Gray HMC Optical lenses – Boris

Production Details

What is the principle of photochromic lenses? In fact, the mystery of photochromic lenses lies in the glass of the lens, which uses a special glass called “photochromic” glass. In the production process, such as silver chloride, silver australia, etc., which are collectively referred to as silver halide, of course, there is also a small amount of copper oxide catalyst, so that the spectacle lenses can be soft from the ink color with the light, and the color will become more and more The lighter, the darker the color as the light gets brighter, this is the magic of silver halide. Silver halide can decompose and combine endlessly, so color-changing glasses can be used all the time. Can color-changing glasses really protect eyes? The answer is of course yes, color-changing glasses can not only darken and brighten with the intensity of light , while also absorbing ultraviolet rays that are harmful to the human eye.

Production Introduction

What kind of photochromic lenses is good?

Let’s talk from the two principles of photochromic lenses: color-changing technology and protection index.

No matter where you are, you need sun protection, and the damage that accumulates from long-term exposure to UV rays is irreversible.

Another light hazard is glare. In sunny weather, especially in summer, glare will not only affect people’s visual clarity, but also cause visual fatigue.

As a result, Boris launched new generation of spin-coating photochromic lenses.

Fast color change:

Compared with other photochromic lenses, our photochromic lens has a faster color-changing speed and a faster response to the environment. From indoor to outdoor, the lens will quickly fade and return to clear and transparent, fading faster than others.

Stable color change performance:

Under the same conditions, as the temperature increases, the color of the photochromic lens will gradually become lighter; on the contrary, when the temperature decreases, the photochromic lens will gradually become darker. Therefore, the discoloration is lighter in summer and darker in winter.

Our lens is less sensitive to temperature, and has stable performance whether it is at high temperature or low temperature, ensuring that the quality of the lens is consistent in different temperature and climate environments.

High protection index:

Our lens has superior ability to resist ultraviolet rays, can filter most of UVA and UVB, and greatly enhance the protection ability of human eyes.

Therefore, wearing photochromic lens is very beneficial from the perspective of eye health. However, the wearing of color-changing glasses should also be combined with their actual needs and usage scenarios. This will maximize the benefits.
