Most people are aware that sunlight contains visible light rays and also invisible ultraviolet rays that can tan or burn the skin. But what many don’t know is that the visible light emitted by the sun comprises a range of different-colored light rays that contain different amounts of energy.
The Different Types of Screen Protectors, First: Tempered glass screen protector. Tempered glass also called toughened glass belongs to safety glass, which plays a good protective role for mobile phone safety. Its characteristics are explosion-proof, scratch-resistant, wear-resistant, and the hardness can reach to 9H (even stroked with a knife), prevent the rupture of the tempered glass caused by accidental impact of the mobile phone from harming the screen and the human body. Easy to paste, no bubbles, the screen transmittance is up to 93%. It can prevent the harm of electronic waves to the human body. Feels better when used with sensitive touch.Discover a few extra info on blue light screen protector.
Your mobile devices: iPhone users can use Night Shift (under Settings > Display) and the less-known Color Tint feature; Android users can download Twilight for their screen-dimming needs.

If you use the computer a lot, you can take care of your eyes by taking frequent short breaks to let your eye relax from the prolonged gazing at the computer. Many people are affected by computer vision syndrome, which is eyestrain from fixing your gaze at the network for a long time. It can also result in pains in the shoulders, neck, back, and neck. Keep your computer monitor at least 4 – 8 inches below the eye level. Take a break and look away from the computer screen every 15 minutes.
Because short-wavelength, high energy blue light scatters more easily than other visible light, it is not as easily focused. When you’re looking at computer screens and other digital devices that emit significant amounts of blue light, this unfocused visual “noise” reduces contrast and can contribute to digital eye strain. Research has shown that lenses that block blue light with wavelengths less than 450 nm (blue-violet light) increase contrast significantly. Therefore, computer glasses with yellow-tinted lenses may increase comfort when you’re viewing digital devices for extended periods of time. The lens in the adult human eye blocks nearly 100 percent of the sun’s UV rays. As part of the normal aging process, the eye’s natural lens eventually blocks some short-wavelength blue light as well — the type of blue light most likely to cause damage to the retina and lead to macular degeneration and vision loss.
