Macbook Pro 16 blue light filter: UV rays have higher energy than visible light rays, which makes them capable of producing changes in the skin that create a suntan. In fact, the bulbs in tanning booths emit a controlled amount of UV radiation specifically for this reason.
Anything above 380 nanometers is not visible to the human eye and cannot be seen. While invisible, these frequencies can still be useful. Some epoxies used in dental work use ultraviolet light to accelerate the chemical process of fixing teeth. Tanning beds use these frequencies to artificially increase tan color (though of course you wouldn’t want to be bathed in it for hours, or you could develop significant health problems).

Some are made with thin tempered glass that also protects your device’s screen from scratches.
Tempered glass screen prtector (aslo called Toughened glass screen protector) is a type of safety glass screen cover processed by controlled thermal or chemical treatments to increase its strength compared with normal glass screen protector. Tempering craft puts the outer surfaces into compression and the inner surfaces into tension.Tempered glass screen prtector is 5 to 10 times more stronger than normal glass screen protector. Tempered glass screen protector is usually made of multi-layered structure, 3-5 layer is most frequently on market.(PERFECTSIGHT best eye care tempered glass screen protectors for iPhone, iPad, MacBook even is up to 11 layer).
