What is the right test way for your blue light blocking glasses or lenses? Now the installation work is basically completed. Press the corners to ensure that the screen protector fits closely with the screen. If there is air bubbles or dust in the middle area, peel up the corner, stick the dust out with dust absorber and then use the squeeze card to drive out the bubble. Finally, use the cleaning cloth and dust absorber to clean the surface of the new screen protector, now your phone has acquired a completely new outlook. How to put on PERFECTSIGHT eye care tempered glass screen protector without bubbles with applicator? Please note: check the dust is on the screen or on the protector after pulling up and insert the tag accordingly.Slide the screen protector with fingers until it fit completely.

Generally, scientists say the visible light spectrum comprises electromagnetic radiation with wavelengths ranging from 380 nanometers (nm) on the blue end of the spectrum to about 700 nm on the red end. (By the way, a nanometer is one billionth of a meter — that’s 0.000000001 meter!) Blue light generally is defined as visible light ranging from 380 to 500 nm. Blue light sometimes is further broken down into blue-violet light (roughly 380 to 450 nm) and blue-turquoise light (roughly 450 to 500 nm).

What are blue light blocking glasses? It is a particular type of glass fitted with filters in the lenses to absorb or block blue light and, in some instances, other detrimental lights from getting through to the user’s eyes. Therefore, the use of these glasses against screens can help reduce exposure to a wave of lights that can keep you awake, especially at night. Exposure to harmful blue light does not mean the end of life. It is presumed that blue light blocking glasses are useful in filtering the blue light, thus restore healthy life to individuals affected. Wearing blue light blocking glasses means healthy sleep, thus reducing the chances of other risks. Read a few more info at benefits of blue light glasses,how do blue light glasses work.

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.

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.

The eye is not very good at blocking blue light. Anterior structures of the adult human eye (the cornea and lens) are very effective at blocking UV rays from reaching the light-sensitive retina at the back of the eyeball. In fact, less than one percent of UV radiation from the sun reaches the retina, even if you aren’t wearing sunglasses. (Keep in mind, though, that sunglasses that block 100 percent of UV are essential to protect these and other parts of the eye from damage that could lead to cataracts, snow blindness, a pinguecula and/or pterygium, and even cancer.) On the other hand, virtually all visible blue light passes through the cornea and lens and reaches the retina. See a few extra info at this site.
