Asthenopia or Digital Eyestrain
What is it and how to Recognise it
Extensive & prolonged use of electronic devices emitting blue light like computer, smartphone and tablet, creates fatigue of Ocular Surface. Usually during the use of these devices, the attention and concentration is high, leading to lesser blinking, decreased lacrimation and lubrication, hence increased discomforts, redness and pain.
This is a temporary condition and a little rest with frequent GOOD BLINKINGR is enough to overcome the fatigue. If the stress persists, it could lead to chronic soreness creating lack of concentration and disorientation from routines.
Urbanised living conditions, adverse environmental conditions and refractive defects, also cause an excessive fatigue of ocular muscles and retina.

Importance of Good Blinking
Blinking exercises are a great way to keep your eyes moist and combat the symptoms of Digital Eye Strain. Blinking stimulates tear production and gives our eyes a chance to clear away any debris, that has accumulated on the surface of the eye.
Individuals who spend a lot of time on the computer or doing focussed work tend to blink lesser than regular. When we don’t blink often enough, the moisture in our eyes evaporates and is not replenished, leaving our eyes tired, dry and itchy.
Blinking exercises are a great way to refresh our eyes and keep them lubricated. They are also easy to do and can be smoothly added to your everyday routine.
