Does blue light from phones damage eyes?

 

Age-related macular degeneration and other vision issues such retinal cell damage from prolonged blue light exposure are both possible outcomes. Moreover, it can aggravate eye cancer, cataracts, and growths on the transparent membrane that covers the white portion of the eye.

Blue light cause eye damage: Blue light in the light spectrum has a shorter wavelength than red, yellow, or green light, carrying more energy as a result. Blue light might be harmful to your eyes due to the additional energy it contains (which is stronger at night). Another chemical in your retinas now typically functions as an antioxidant to stop the ageing of eye cells. Yet, the continual exposure to blue light may outweigh the antioxidant effect and increase one's risk of macular degeneration.

The Use of Cell Phone in the Dark:  Blue light emissions from laptop and smart phone screens have been linked to macular degeneration, the most common cause of vision loss in the US, despite appearing to be safe to the eyes. Although macular degeneration typically affects people over 60, experts believe that with the rising usage of blue light technologies, this may happen sooner.

  • The death of photoreceptor cells in the retina causes macular degeneration.
  • The retinal molecule is used by photoreceptor cells to record visual images and transmit them to the brain.
  • Blue light stimulates the eye's production of retina, which then sets off a number of chemical processes. These ocular responses may poison the molecules in the photoreceptor cell, causing harm.
  • There is no regrowth after these photoreceptor cells die.

Blue light affect sleep: Blue light impacts when our bodies produce melatonin, which can cause sleep patterns to be disturbed. Type 2 diabetes, cardiovascular disease, cancer, sleep difficulties, and cognitive dysfunctions can all be caused by circadian rhythm disruption.

Although there have been numerous studies on blue light glasses, there isn't general agreement that they reduce eye strain. Nonetheless, they can aid in preventing eye strain brought on by excessive blue light exposure. Blue light glasses may be useful if you use digital devices frequently and have digital eye strain.

People can sleep better and stay asleep longer if they use blue light spectacles during the day. Blue-light-blocking generic lenses lessen adverse effects by 10% to 23% without sacrificing quality. Long-term use of digital gadgets may be more comfortable when using computer glasses with yellow-tinted lenses.

 How can I reduce negative effects of blue light:

  • Get blue-light filters for your computer, tablet, and smartphone screens. While maintaining the     clarity of the display, the filters greatly reduce the amount of blue light that reaches your eyes.
  • To lessen digital eye strain, adhere to the 20-20-20 rule. every 20 minutes, take a 20-second break to look at anything 20 feet away.
  • Your device's screen illumination and glare can be adjusted. Establish a comfortable viewing distance and stance. Verify that all vision issues, no matter how little, are addressed correctly.
  • When you have your next eye exam, discuss digital device use and blue light protection with your eye doctor.
