Staring at your mobile in the night could harm your eyes

If you are in a habit of using mobile phone after you put off the lights, lying in bed, then change your habit before it’s too late. The continuous use of mobile phones before bedtime in the dark can cause extensive strain to your eyes.
This habit can initially cause dry eyes, and strain your eyes. Direct glare of over 30 minutes can even cause irreversible eye macular degeneration, resulting in rapid deterioration of vision.
The concern for this stems from the fact that the mobile devices expose us to high energy visible (HEV) light or blue light, which in certain experiments in laboratory with high dose of exposure has shown to cause changes in certain cells of the eyes.
“The HEV light or blue light is also part of the light from LEDs and sunlight. However, we are not exposed to this for long hours as we rarely stare at these sources of light for a long time,” he says.
K. Bhujang Shetty, chairman and managing director of Narayana Nethralaya,also revealed that eyes could be affected only after continuous and prolonged use of mobile phones in the dark. “This habit may not cause enough damage that can lead to permanent vision loss if a person uses it occasionally. But it would definitely strain the eyes,” he says.
THe doctors suggest some precautions, including maintaining a comfortable working distance from the device — be it a mobile phone or computer and ensure that the screen is bright enough and the fonts big enough to read comfortably.

It is also advisable for a person to follow the rule of 20s — every 20 minutes, stare at an object 20 feet away for 20 seconds. This will bring back your blink rate to normal and also relax the muscles in your eye.
