Digital Eye Strain

The recent shift in lifestyle is that we are locked indoors. This has posed new challenges. One of them is the forcible overuse of computers, laptops, mobiles and other light emitting sources.

These are however compulsory tools to continue our businesses , social interaction , education or recreation. Sadly we are overusing our eyes which are the most sensitive and vital of our sense organs.

The symptoms experienced by excessive use of screen is summed up as Computer Eye syndrome or digital eye strain.

What can one experience?

Burning of eyes, itchy and red eyes, brow ache, double vision, watering of eyes, blurry vision, headache, intolerance to light, dark circles, insomnia ( sleeplessness).

Why does this happen ?

1. Eyes are rested when we close them or watch a distance. Close work for long hours , causes eye muscles to fatigue

2. Excess staring at screen causes dry eyes due to reduced blink rate and excess evaporation of tears from the surface of eyes

3. Working in bad lighting and at night allows excess light into retina ( eye nerve ) and disturbs sleep cycle and leads to dark circles too

4. The electro magnetic waves are said to have degenerative effects on eye tissues causing early cataracts and age related retinal issues
