Asthenopia Or Eye Strain

It is a condition of ocular fatigue due to a prolonged use of electronic devices with blue light (computer, smartphone and tablet), but also to adverse environmental conditions or refractive defects (myopia, hyperopia etc.) that cause an excessive fatigue of ocular muscles and retina.

Usually during the use of these devices the attention and concentration are high and it could lead to a lower winking, decreased lacrimation and increased bother, redness, and pain.

Usually this is a temporary condition and just a little rest is enough to already note an improvement. However a prolonged condition of stress could leads to a chronic soreness that makes the sufferer unable to concentrate properly and perform normal daily activities.
