PC lens is polycarbonate (polycarbonate) abbreviation, PC lens is also known as space film is very light.
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!
At the same time, it also inherits the excellent characteristics of super impact resistance of raw materials, so this material is also commonly known as bulletproof glass after thickening!
The advantages of PC 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, protective and other comprehensive needs of the wea
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.
The electromagnetic rays just beyond the red end of the visible light spectrum are called infrared - they are warming, but invisible. (The "warming lamps" you see keeping food warm at your local eatery emit infrared radiation. But these lamps also emit visible red light so people know they are on! The same is true for other types of heat lamps.)
On the other end of the visible light spectrum, blue light rays with the shortest wavelengths (and highest energy) are sometimes called blue-violet or violet light. This is why the invisible electromagnetic rays just beyond the visible light spectrum are called ultraviolet (UV) radiation.
