How To Filter Blue Light on Mobile Devices

We use our mobile devices for several hours. This causes digital eyestrain because electronic device screens emit blue light.

What is Blue Light?

Blue light is part of the visible light spectrum. The visible spectrum contains blue, orange, green, yellow, and red light rays. Red, yellow, and green light rays have long wavelengths. They have less energy than blue and violet rays.TT

The electromagnetic rays on the blue end of the spectrum have short wavelengths. This means they have more energy than infrared lights.

Blue light is a high-energy visible (HEV) light. It is a high-frequency light in the blue/violet band on the visible spectrum. It has been known that it can damage the retina. It can also cause age-related muscular degeneration (AMD) and digital eye strain.

The screens of digital devices and personal computers emit short-wave blue light. This can contribute to various health problems.

Few things you should know about EMF radiation (blue light) and how it affects your eyes.

Blue light is emitted from the sun, but also from electronic device screens such as our computer display screens, tablets, and mobile phones. The issue with blue light in technology is the amount of exposure we receive and how close we hold our gadgets to our faces. Many healthcare professionals are concerned about the potential long-term effects of blue light exposure. Blue light can cause eye strain, and even contribute to macular degeneration. Our eyes aren't that great at blocking blue light, but there are some things we can do to shield ourselves!

  •  This study have shown that blue light penetrates all the way to the retina and damages light - sensetive cells.
  • In 2001, German scientists found a link between cell phone radiation and eye cancer. The study investigated a form of eye cancer called uveal melanoma, in which tumours form in the layer that makes up the iris and base of the retina. The research suggests there is a threefold increase in eye cancers among people who regularly use the devices. ("Scientists Link Eye Cancer to Mobile Phones")
  •  A group of Israeli researchers found a link between microwave radiation and the development of cataracts. The study shows that prolonged exposure to microwave radiation similar to that used by cellular phones can lead to both macroscopic and microscopic damage to the lens and that at least part of this damage seems to accumulate over time and does not seem to heal. ("Cell Phone Radiation May Cause Visual Damage")
