What is Nano liquid screen protector? 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.
What is blue light? Sunlight contains red, orange, yellow, green and blue light rays and many shades of each of these colors, depending on the energy and wavelength of the individual rays (also called electromagnetic radiation). Combined, this spectrum of colored light rays creates what we call “white light” or sunlight.
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.

We can also expect to see new phone releases later this year that integrate blue light-reduction dye, and the Consumer Electronics Show in January 2019 will show off commercial grade products which incorporate these features. Product designers should help accelerate this change by working with companies to integrate HEV-blockers right into the screens of the products they create. Also consider indicator colors on connected electronic devices; a warm orange will always be more welcome than a bright blue. Until the tech industry fully addresses the problems caused by blue light, there’s a number of steps we can take — in our household, and in our civic halls.
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.
Blue light exposure may increase the risk of macular degeneration. The fact that blue light penetrates all the way to the retina (the inner lining of the back of the eye) is important, because laboratory studies have shown that too much exposure to blue light can damage light-sensitive cells in the retina. This causes changes that resemble those of macular degeneration, which can lead to permanent vision loss. Although more research is needed to determine how much natural and man-made blue light is “too much blue light” for the retina, many eye care providers are concerned that the added blue light exposure from computer screens, smartphones and other digital devices might increase a person’s risk of macular degeneration later in life.
