What is glare?

What is the damage of the blue light? Applying Screen protectors properly without annoying bubbles or dusts for phones and tablets can be the most frustrating job. In this article you’ll get some useful tips on how to put on a screen protector directly to avoid any bubbles or trapped dirts. This methoud apply to different mertials’ screen protecotr for phone and tablets like tempered glass, plastic, PET film, liquid film, etc. After aligning the upper part, slowly adjust the position of the whole screen protector appropriately to ensure the position is correct, and then place the lower half on the screen.

UV rays have higher energy than visible light rays, which makes them capable of producing changes in the skin that create a suntan. In fact, the bulbs in tanning booths emit a controlled amount of UV radiation specifically for this reason.

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.

Anything above 380 nanometers is not visible to the human eye and cannot be seen. While invisible, these frequencies can still be useful. Some epoxies used in dental work use ultraviolet light to accelerate the chemical process of fixing teeth. Tanning beds use these frequencies to artificially increase tan color (though of course you wouldn’t want to be bathed in it for hours, or you could develop significant health problems).

Allow distance. Being too close to your screen is also a factor in how your eyes can be negatively affected—they have to work harder to see things that are closer. If possible, keep your monitor or screen about 25 inches away, or about an arm’s length away. Make sure to position the screen so your eye gaze is directed slightly downward. Adjust the brightness. When a screen is much brighter than the surrounding light, eyes have to work harder. If you can, adjust your room lighting and try increasing the contrast on your screen.

Like ultraviolet radiation, visible blue light — the portion of the visible light spectrum with the shortest wavelengths and highest energy — has both benefits and dangers. Here are important things you should know about blue light: Blue light is everywhere. Sunlight is the main source of blue light, and being outdoors during daylight is where most of us get most of our exposure to it. But there are also many man-made, indoor sources of blue light, including fluorescent and LED lighting and flat-screen televisions. Most notably, the display screens of computers, electronic notebooks, smartphones and other digital devices emit significant amounts of blue light. Discover even more info on www.perfectsight.co.
