Asthenopia or eye strain
WHAT IS IT ABOUT AND HOW TO RECOGNIZE IT
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 is high and it could leads to a lower winking, decreased lacrimation and increased bother, redness and pain. Sollecitando gli occhi a lungo con questi dispositivi ad una distanza ravvicinata il rischio maggiore è per la retina, che può subire danni sul lungo periodo.
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.
