Eyestrain is a common cause of headache. In such cases, an eye specialist should be consulted and proper treatment taken. Simple eye exercises such as moving the eyes up and down and from side to side, palming, rotating the head, with neck outstretched, forward and backwards three times, then three times clockwise and three times counter clockwise, can relieve eyestrain.
A surprising way to relieve eyestrain is to give gentle massage to the neck. Bring the shoulders together and release. Then take a few minutes to place a moist cool compress over the eyes to
give them rest and recuperation.
