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.

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.

Your home: “Smart” appliances like refrigerators often boast a touchscreen with bright blue display. Consider adding a small “drape” or other cover to put over appliance screens, so they doesn’t blast you into insomnia, when you go into the kitchen for a late night glass of water. Appliances with LED-based bulbs are another common culprit — a topic I’ll cover in my next post. Your laptop and appliances: Use Flux at night to slowly decrease your computer’s blue glow as the sun sets. Buy a glare-reducing protective screen cover. Don’t buy electronics with lots of blue light — of if you do, cover the bulbs. Use blue-light protective glasses at night if you can’t avoid using your devices, or can’t entirely block out blue light in your environment.

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.

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.
