How to put screen protector on: 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.

You may be wondering why using a computer is so much harder on your eyes than reading printed materials like a book or magazine. The main reason is that when we stare at computer screens, we tend to blink less. In fact, while focusing on digital displays, a person’s blink rate can be reduced by a third to a half, which causes their eyes to dry out. Additionally, many of us are not viewing these screens from the optimal distance. In recent years, a popular solution to this problem has been blue light filters; namely, expensive computer glasses. However, these glasses, as well as other blue light filters, are no more effective at reducing the symptoms of eye strain than a neutral filter. Instead of spending money on something that may not help, try these simple and effective tips first.

Adults have their own issues to deal with. As we age, our eyes “remember” and retain energy. Blue light not only penetrates all the way to the retina in the back of the eye, it builds up over time. The cumulative effect causes eye strain, dry eye, and unnecessary exhaustion. Because of its temperature and frequency, blue light tends to affect both the retina and the cellular anchors, leading to early onset of Advanced Macular Degeneration, an issue which must be corrected through surgery. Consistent melatonin disruption has also been linked in recent studies to an increased risk of obesity and some cancers.

But too much exposure to UV causes a painful sunburn — and even worse, can lead to skin cancer. These rays also can cause sunburned eyes — a condition called photokeratitis or snow blindness. But ultraviolet radiation, in moderation, also has beneficial effects, such as helping the body manufacture adequate amounts of vitamin D. See a few more info at Perfectsight ipad screen protectors.
