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.
In daily artificial lighting, when the illumination is 100–300lx and the flash frequency is not less than 150HZ, the light is more suitable for the human eyes. When the illumination is too strong, and the flash frequency is insufficient, it is easy to cause eye fatigue, which may cause ametropia in the human eye. When watching the mobile phone for a long time, the glare that is constantly flashing on the screen will cause continuous stimulation to the eyes. When the eyes keep capturing these light and shadows, the eyes will feel tired and cause damage to the tear film on the surface of the eyeball, causing dry eyes and deepen the myopia. Read a few extra info on what is anti glare screen protector.
Your mobile devices: iPhone users can use Night Shift (under Settings > Display) and the less-known Color Tint feature; Android users can download Twilight for their screen-dimming needs. If you can’t help bringing your phone to bed, wear HEV blocking glasses, put a blue filter screen on your phone, or place it face down while it plays; play a movie or ambient white noise, or podcast clips to listen to while falling asleep. Or better yet, drift off while reading an analog book: It will force your brain to imagine, and that effort will wear you out more than the instant simulation brought by the visual nature of our devices.
If you use the computer a lot, you can take care of your eyes by taking frequent short breaks to let your eye relax from the prolonged gazing at the computer. Many people are affected by computer vision syndrome, which is eyestrain from fixing your gaze at the network for a long time. It can also result in pains in the shoulders, neck, back, and neck. Keep your computer monitor at least 4 – 8 inches below the eye level. Take a break and look away from the computer screen every 15 minutes.
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.
