Best Blue Light Glasses – Best Computer Glasses 2020

Are Blue Light Glasses OR Computer Glasses Worth It?

Glasses that claim to filter blue light from computers, smartphones, and tablets are becoming increasingly popular. Advertising on these glasses claims that blue light can be very annoying. From dry eyes to digital eye strain, sleep disturbances, and even macular degeneration, blue light range problems are speculated, causing people to lose some or all of their central vision. However, there is no evidence that the kind or amount of light coming from computer screens is damaging to the eyes.

“Everyone is concerned that it may be harmful to the eye, and this is a valid concern, but there is no evidence that it can cause irreversible damage.”

What is blue light?

Every light we see, from red to violet, covers the full spectrum of the rainbow. Inside this spectrum are waves of blue light, which are said to help us stay alert and excited.

What gives off blue light?

Any source of visible light gives off blue light waves, whether it’s the sun, a touchscreen, or a light bulb.

We get plenty of blue light waves each day from the sun, but after dark, we’re still exposed to it from many artificial sources.

How does blue light affect sleep?

When the sun goes down, the lack of light signals our bodies to start producing melatonin, the hormone responsible for our sleep.

Before the advent of artificial light, the sun regulated our sleep schedules. But today, we are exposed to light all day and night. Although our bodies experience any light waves after a dark delay in the production of melatonin, blue light waves can be especially troubling because they keep us alert.

On the other hand, blue light can help us overcome sleep issues by disrupting our usual circadian rhythm. The Lumos mask, for example, uses light therapy to mitigate the effects of jet lag.

Should You Be Worried About Blue Light and Computer Radiation?

There is evidence that exposure to light can damage the eyes in certain conditions. For example, too much exposure to ultraviolet light from the sun increases the risk of eye diseases, including cataracts, growth on the eye, and cancer. 

The amount of radiation from any computer has never been demonstrated to prevent eye disease. A study reprinted by the National Library of Medicine found no UVA or UVB radiation measured by computer monitors. The most effective part of sunlight for the eyes and skin is UV radiation. Radiation Protection at the Massachusetts Institute of Technology summarizes current research on the radiation of computer monitors, stating that “no data have been developed to suggest a health risk from exposure to electromagnetic fields associated with the use of monitors.” Counts do not exist. “

Long hours staring at digital screens can cause eye strain, and computer-related blinking can cause blinking eyes. But these effects are due to how people use their screens, not because of anything coming from the screens.

You can protect your eyes from strain if you work with computers all day:

  • Sit about 25 inches (arm’s length) from the computer screen. Position the screen so you are gazing slightly downward.
  • Reduce screen glare by using a matte screen filter if needed.
  • Take regular breaks using the “20-20-20” rule: every 20 minutes, shift your eyes to look at an object at least 20 feet away for at least 20 seconds.
  • When your eyes feel dry, use artificial tears to refresh them.
  • Adjust your room lighting and try increasing the contrast on your screen to reduce eye strain.

If you wear contact lenses, give your eyes a break by wearing your glasses.

Give Your Eyes a Break

If you’re worried about how computers and other blue light-emitting screens are affecting your eyes, you can find relief without special eyewear.

The American Academy of Ophthalmology, the Vision Council, and other vision-related organizations urge moderation in screen use. Most of them recommend adopting the 20-20-20 rule. That means that every 20 minutes you’ll look at an object at least 20 feet away for 20 seconds.

The American Academy of Ophthalmology also recommends taking these steps:

  • Adjust your seat or the position of your computer, so your eyes are about 25 inches from the screen. Position the screen so you’re gazing slightly downward.
  • Use a matte screen filter on the screen to reduce glare.
  • Use artificial tears when your eyes feel dry.
  • Pay attention to the lighting in the room where you work. You might try increasing your screen contrast.

If you wear contact lenses, give your eyes a break by wearing glasses now and then.
