How to choose blue light blocking glasses? 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.
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.
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.
If you use the computer a lot, you can take care of your eyes by taking frequent short breaks to let your eye relax from the prolonged gazing at the computer. Many people are affected by computer vision syndrome, which is eyestrain from fixing your gaze at the network for a long time. It can also result in pains in the shoulders, neck, back, and neck. Keep your computer monitor at least 4 – 8 inches below the eye level. Take a break and look away from the computer screen every 15 minutes.
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. Find a few more details at perfectsight.co.
