How to apply tempered glass screen protector without bubbles: 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.
Then use the same method to pry the other three corners of the screen protector, and use a little more force when smashing, so that the four sides of the screen protector can be pulled up. After the four corners are picked up, grab the lower corner and pull up. Then the whole screen protector will start to loosen, and then pull up the four corners until it is removed. Congratulation: the task of removing the old screen protector is now completed. At this point, the screen protector will automatically stick to the screen and slowly expand to the surrounding area. Take out the squeeze card, press the edge from the top to the bottom, and drive the bubbles away. Read extra info on how to put on glass screen protector.
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.
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.
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.
