Tempered glass screen protector purchase guides: Blue light exposure may increase the risk of macular degeneration. The fact that blue light penetrates all the way to the retina (the inner lining of the back of the eye) is important, because laboratory studies have shown that too much exposure to blue light can damage light-sensitive cells in the retina. This causes changes that resemble those of macular degeneration, which can lead to permanent vision loss. Although more research is needed to determine how much natural and man-made blue light is “too much blue light” for the retina, many eye care providers are concerned that the added blue light exposure from computer screens, smartphones and other digital devices might increase a person’s risk of macular degeneration later in life.
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.

Dry eye can result in a series of problems with your eyes apart from making your eyes irritated or itchy. Although dry eyes can be linked to your age, you can take measures to prevent it, like using eye drops or turning on the humidifier in your home or office to relieve the condition. If it persists, you can contact your optometrist for advice or treatment. You may have to stop diuretic medicine.

The ultraviolet rays can damage your eyes. Why endangering your eyes when you can get a good pair of sunglasses for a few bucks?
Understanding the physics of light and how it interacts with the human eye is the first step to understanding why too much of it can be bad for us. All light is waves, and different colors have different energies. Towards the beginning of the visible spectrum is red light, made up of low energy waves. This light is easier on our eyes, especially at night. As we get closer to the higher energy side of the spectrum, light becomes more tiresome for our eyes to process. Blue light occupies the highest energy portion of the visible spectrum. It penetrates all the way to the retina in the back of the eye.
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. Read additional details on this website.
