Color changing lens, also known as "photosensitive lens". The glass lens is added with silver halide, but at present the mainstream is resin discoloration lens, in the acrylic resin lens with the addition of Pyrex ring and other chemicals, so that the original transparent and colorless lens, in the event of strong light irradiation, will become colored lens, to do protection, so it is suitable for indoor and outdoor use at the same time.Color changing lens is made of optical glass containing silver halide microcrystal. According to the principle of reversible reaction of light color tautometry, it can quickly darken under sunlight and ultraviolet radiation, completely absorb ultraviolet light, and show neutral absorption to visible light. Back to the dark, can quickly restore colorless transparent.Color-changing lenses are mainly used in the open air, snow field, indoor strong light workplace, to prevent the damage of sunlight, ultraviolet light, glare on the eyes.Light blue lens: the beach can wear the sun blue lens, blue can effectively filter the sea water and sky reflection of light blue. Blue lenses should be avoided when driving, as they can confuse us with the color of traffic signals.
Spin coating Lens : Spin coating Lens adopts spin change technology, which completely subverts the previous basic change technology. Compared with base transformation, it is uniform and has no background color; Compared with the traditional film changing method, it is superior to the soaking method. The color changing liquid and the hardening liquid are placed in different processes, which not only ensures the adhesion of the color changing liquid, fully maintains its color changing tension, but also exerts the hardening fixation effect and strengthens the hardness. With double-layer spin coating technology and hardening protection, the process quality is greatly improved.Advantages: rapid and uniform color change. It is not limited by the material, and any ordinary aspheric surface, 1.56, 1.61, 1.67, 1.74, etc. can be processed into a film-changing lens. There are more varieties, and consumers have more choices.
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 brokenThe 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.
What is Lens Index?The lens index refers to the index of refraction (otherwise known as refractive index) of lens material for eyewear. It is a relative measurement number that describes how efficiently the material bends light. Light refraction will depend on how quick light itself passes through the lens.
