Tempered glass screen protector repair tips: 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.

Dry eye can result in a series of problems with your eyes apart from making your eyes irritated or itchy.

If it persists, you can contact your optometrist for advice or treatment. You may have to stop diuretic medicine. If you walk in the sun often or the nature of your work requires spending a few hours in the sun, protect your eyes by wearing sunglasses to protect your eyes from the ultraviolet rays that come from the sun. 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.

Visible light is much more complex than you might think. Stepping outdoors into sunlight; flipping on a wall switch indoors; turning on your computer, phone or other digital device — all of these things result in your eyes being exposed to a variety of visible (and sometimes invisible) light rays that can have a range of effects.
