The main performance is safety explosion-proof, you even use hammer hit it is not necessarily broken
The history of PC material lenses is relatively shorter, but thanks to the application of high quality raw materials, and ordinary resin lenses have essential differences!
The advantages of PC material lens
(1) PC material itself has the function of uv protection, uv protection function is strong, almost 100% uv protection ability;
At the same time, the material is not easy to change color (ordinary resin lenses are easy to yellow);
(2) Lighter weight, currently the lightest kind of optical lens;
If there is no problem in the process, the weight of the lens will be about 30% lighter than ordinary resin pieces, and about 50% lighter than glass pieces;
(3) PC material is a viscous material, strong toughness, not easy to break, and has a strong impact resistance, 10 times stronger than resin sheet impact resistance, more than 60 times stronger than glass sheet;
(4) Due to the characteristics of high refractive index and light specific gravity, now a variety of multi-functional and multi-purpose PC lenses have been introduced; To meet the physiological and protective needs of the wearer.
Spin coating change lens adopts spin change technology, completely subvert the previous base change technology. And base change ratio, it is uniform without background; Compared with the traditional film, it is better than immersion, the discoloration liquid and hard liquid in different processes, not only to ensure the adhesion of the discoloration liquid, fully maintain the discoloration tension, but also play a hard fixing effect, strengthen the hardness. With double layer rotary coating technology and hard protection, the process quality is greatly improved.
What Is Blue Light?
\Sunlight contains red, orange, yellow, green and blue light rays and many shades of each of these colors, depending on the energy and wavelength of the individual rays (also called electromagnetic radiation). Combined, this spectrum of colored light rays creates what we call "white light" or sunlight.
Without getting into complicated physics, there is an inverse relationship between the wavelength of light rays and the amount of energy they contain. Light rays that have relatively long wavelengths contain less energy, and those with short wavelengths have more energy.
Rays on the red end of the visible light spectrum have longer wavelengths and, therefore, less energy. Rays on the blue end of the spectrum have shorter wavelengths and more energy.
| 1. Could you provide samples? |
| Of course, free samples can be sent to you, but please help us pay the freight fee. |
| 2. What Certification do you have for your optical lens? |
| FDA, CE, ISO9001 certification is available. |
| 3. What is the MOQ of optical lens? |
| We dont have Min Order quantity requirement. But if the quantity order is too small, we have to charge extra delivery fee. |
| 4. Could you provide OEM service? |
| Sure, just send us your requirements. |
