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.
The Different Types of Screen Protectors, First: Tempered glass screen protector. Tempered glass also called toughened glass belongs to safety glass, which plays a good protective role for mobile phone safety. Its characteristics are explosion-proof, scratch-resistant, wear-resistant, and the hardness can reach to 9H (even stroked with a knife), prevent the rupture of the tempered glass caused by accidental impact of the mobile phone from harming the screen and the human body. Easy to paste, no bubbles, the screen transmittance is up to 93%. It can prevent the harm of electronic waves to the human body.

Your glasses and contacts: Talk with your optometrist about purchasing eyeglasses or contact lenses with HEV filters already built in. It’s a good idea if you plan to use your devices all day, without many breaks. You can also wear special computer glasses. TrueDark is an eyewear company that sells blue-light blocker glasses that look just like regular glasses. The company just announced two clear-lens blue-light filter glasses that block around 40% of high energy visible light. TrueDark also produces special night-time glasses that filter out all high energy visible light that you can wear over your glasses to block out 100% of blue light caused by LED lights, devices, and streetlights an hour before bedtime for optimum sleep.
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.
If you have cataracts and are about to have cataract surgery, ask your surgeon what type of intraocular lens (IOL) will be used to replace your cloudy natural lens, and how much blue light protection the IOL provides. After cataract surgery you might benefit from eyeglasses that have lenses with a special blue light filter — especially if you spend long hours in front of a computer screen or using other digital devices. So, is all blue light bad for you? Why not block all blue light, all the time? Bad idea. It’s well documented that some blue light exposure is essential for good health. Research has shown that high-energy visible light boosts alertness, helps memory and cognitive function and elevates mood. In fact, something called light therapy is used to treat seasonal affective disorder (SAD) — a type of depression that’s related to changes in seasons, with symptoms usually beginning in the fall and continuing through winter.
