Anti Blue light Eyeglass Lenses

What is Blue Light and Ultraviolet Light?
Blue light is part of the visible light spectrum and is emitted by the sun and artificial light sources such as LEDs, computers, and smart phones. Blue-violet light can have a harmful impact on the eyes, specifically the retina. It is also a risk factor for the onset of age-related macular degeneration, a deterioration of the part of the retina responsible for sharp, central vision.
Ultraviolet light not only affects the skin by increasing the risk of skin cancer, it can also be dangerous for the eyes. Excessive exposure to UV light without proper protection can lead to cataracts. It can also cause a sunburn on the cornea of the eye (known as photokeratitis), which can lead to temporary blindness.

Through the perfect combination between the reflective index of nonmetallic Oxide and optical technology, 16 layers are formed by the advanced vacuum machine. These layers of coating allows beneficial blue light to pass through the lens while filtering out the dangerous blue-violet light, especially the blue light of 430nm that can cause age-related macular degeneration.

Blue light is emitted by a plethora of electronic devices including cell phones, tablets, and laptop computers. A recent study found that Americans spend almost 2 ½ hours on their tablets and smart phones every day, meaning protection against blue light is important for anyone using a digital device on a regular basis. Another source of blue light is energy efficient technology in the form of fluorescent light bulbs and LED lights. Most offices and stores use fluorescent light bulbs, thus putting your eyes at risk if unprotected.
It’s important to protect your eyes against UV exposure both indoors and out. Our eyes are exposed to UV radiation 365 days a year, even on cloudy days. In fact, up to 40% of UV exposure occurs when we aren’t in full sunlight. Since most people are at risk for overexposure to both blue light and UV light on a daily basis, it’s important to consider the anti blue light lens that can protect your eyes from harmful blue light and ultraviolet light.

TR90—Durable, Lightweight, Flexible

TR90 was produced through Swiss technology as a thermoplastic material that is incredibly durable, flexible, and lightweight. Glasses made with TR90 are extremely comfortable because they have a flexible quality. Since they are flexible, they can bend under pressure and contour your face comfortably.
This flexibility also makes TR90 glasses resilient to damage. Because the material is pliable, they are far less likely to break or bend from impact. Finally, and most remarkable of all, TR90 glasses are supremely lightweight. Sometime you even don’t feel it there while you wear.

TPE—Softness, environmental friendly

TPEs are a family of rubber like materials that combine the characteristics of rubber with the recyclability and processing advantages of plastics.
Like thermoplastics, when heated and with the application of shear force, TPEs become free-flowing and when cooled regain their original structure and stability. Unlike the chemical cross-linking which occurs in thermoset rubbers, TPE involves purely physical cross-linking, which can be reversed via the further application of heat, this makes it possible to re-use all production waste and end of life products can be easily reprocessed.
It is this design flexibility, high-performance and ease of processing that has led to designers increasingly turning to TPEs as their material of choice. TPEs are used in a variety of applications in the automotive, medical, construction, electrical, appliance, packaging and industrial markets – and new uses for TPEs are being developed all the time.
TPEs exhibit elasticity similar to that of a cross-linked rubber. TPEs are available to be ultra-soft, which is comfort and safe as kid glasses.
