Tempered glass screen protector without bubbles repair guides: The amount of HEV light these devices emit is only a fraction of that emitted by the sun. But the amount of time people spend using these devices and the proximity of these screens to the user’s face have many eye doctors and other health care professionals concerned about possible long-term effects of blue light on eye health. The short-wavelength, high-energy light rays on the blue end of the visible light spectrum scatter more easily than other visible light rays when they strike air and water molecules in the atmosphere. The higher degree of scattering of these rays is what makes a cloudless sky look blue.
How to Clean the phone screen? Clean up the screen with alcohol pad.Make sure there is no dust and stain. Then wipe dry the water stain with the cleaning cloth. Then take out the dust absorber and pull it out from the arrow to open it. The dust absorber can absorb the dust on the screen. Hold the arrow of the dust absorber, stick on and take off from the screen, then change the different positions and repeat this action for several times until the screen looks clean and dust-free. Then observe the screen, repeat the use of cleaning cloth and dust absorber for screen cleaning, ensure that there is no dust and stain on the screen and it looks clean like a mirror, then the cleaning work is completed.

Eye tip: This one should come as no surprise – the food we put in our bodies plays a vital role in our health. You want to be sure you’re eating foods with plenty of nutrients including omega-3 fatty acids, Zinc, Vitamins A, C, & E. Here are some of the foods that contain these vision-enhancing nutrients: Omega-3 Fatty Acids, which can help to reduce the symptoms of dry eye, can be found in several natural food sources including salmon, mackerel, tuna, walnuts, chia seeds and tofu.
Artificial blue light, the kind associated with LED and screen-based OLED illumination, operates on a different level of the spectrum, in the 380–500 nanometer range. The 415–455 nanometer range is the most harmful — what’s called high-energy visible light, or HEV — and it’s where digital blue light from laptops, tablets and mobile phones operate. Sunglasses are designed to block light in this range — as are welding helmets! But the tech industry has been slow to adjust. “Apple for sure doesn’t build to that standard,” Bill pointed out.
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. Explore even more details at www.perfectsight.co.
