Causes of eye fatigue (tiredness) & pain

2008-12-07T04:15:00.000-08:00

Asthenopic symptoms in the eye are responsible the morbidity in CVS. Proper rest to the eye and its muscles is recommended to relieve the associated eye strain. A routinely recommended approach is to blink the eyes frequently (this helps replenish the tear film) and to look out the window to a distance object or to the sky—doing so provides rest to the ciliary muscles. One of the catch phrases is the "20-20-20 rule": every 20 minutes, focus the eyes on an object 20 feet (6 meters) away for 20 seconds. This basically gives a convenient distance and timeframe for a person to follow the advice from the ophthalmologist. Otherwise, the patient is advised to close his/her eyes (which has a similar effect) for 20 seconds, at least every half hour.

Decreased focusing capability is mitigated by wearing a small plus-powered (+1.00 to +1.50) over-the-counter pair of eyeglasses. Wearing these helps such patients regain their ability to focus on near objects. People who are engaged in other occupations—such as tailors engaged in embroidery—can experience similar symptoms and can be helped by these glasses
