Screen protector install tricks: The light sources for this therapy emit bright white light that contains a significant amount of HEV blue light rays. Also, blue light is very important in regulating circadian rhythm — the body’s natural wakefulness and sleep cycle. Exposure to blue light during daytime hours helps maintain a healthful circadian rhythm. But too much blue light late at night (reading a novel on a tablet computer or e-reader at bedtime, for example) can disrupt this cycle, potentially causing sleepless nights and daytime fatigue. If you are using your phone constantly — especially if you use it primarily for texting, e-mailing and web browsing — a convenient way to reduce your blue light exposure is to use a blue light filter. Digital electronic devices emit blue light that can cause eye strain and may lead to eye problems over time. These filters are available for smartphones, tablets, and computer screens and prevent significant amounts of blue light emitted from these devices from reaching your eyes without affecting the visibility of the display. Some are made with thin tempered glass that also protects your device’s screen from scratches.
How to install a screen protector perfectly without bubbles and alignment tool ? Warm Tips: Before the installation,please make sure the doors and windows are closed.Try to keep the invironment clean and avoid the occurrence of dust or lint. Take out the new screen protector, wipe it with a cleaning cloth, make sure there is no dust on the outside, then grab the top of the backboard and then tear off the screen protector. Put the upper part on the phone screen, first align the upper part of the screen protectoe with the upper part of phone screen, and compact it slightly. Read a few more info on how to apply tempered glass screen protector without bubbles.
Avoid dry eyes. As stated above, the primary reason staring at a computer screen is so harmful to your eyes is that you tend to blink less. To combat dry eyes, keep artificial tears nearby and use them when necessary. Other factors that can cause dryness include humidity-controlled offices that pull moisture out of the air and, during the winter, heaters. A desktop humidifier can help introduce moisture into your environment and give your eyes some relief.
It’s no surprise that nearsightedness is the number one eye issue in the world right now. In 2016–2017, we spent an average of 10.4 hours on our devices a day. It’s why many if not most of us deal with eyes that feel “shot” — dry, itchy, sometimes accompanied by a headache, what’s occasionally called “computer vision syndrome”. Different age levels require different levels of protection. Children under the age of 14 who use tablets and phones with high energy light are at special risk. Until 14, their corneas aren’t fully developed, and lack the protection of adult eyes — especially if they’re constantly in front of a device. Increased and prolonged exposure to HEV is a contributing factor to increased diagnoses of nearsightedness among children.
Without getting into complicated physics, there is an inverse relationship between the wavelength of light rays and the amount of energy they contain. Light rays that have relatively long wavelengths contain less energy, and those with short wavelengths have more energy. See more info at Perfectsight ipad screen protectors.
