Myth: Smartphones cannot permanently damage your eyes
Fact: Too much screen time may wreck your eyes, especially at night.
Blue light in particular that is transmitted by smartphones may be toxic to your eyes. The specialized photoreceptors located in the retina are damaged by blue light and can lead to Macular degeneration, a major cause of vision loss worldwide. It can also lead to digital eyestrain. This however does not lead to permanent damage. Dry eyes can also be caused or worsened by blue light.
Protect your eyes from blue light. Reduce screen time especially at night. At least rest your eyes by looking away from your screen from time to time. Put your phone on the ‘night shift’ setting (Apple iPhone) or use a ‘blue light filter’ (Samsung). Hold your phone farther away from your eyes: 40-45 cm. It may be strange at first but you will get used to it.
Don’t get blinded by bad habits.
