Eyestrain and headache can be understood in two senses: First, if one experiences astigmatism when viewing objects, accompanied by headaches and eye pain, it is possible that glaucoma is present. This condition is also associated with increased eye pressure and swelling pain in the eyes. If this is the case, treatment to lower eye pressure and treat glaucoma is necessary. The second meaning involves astigmatism identified through an eye examination, indicating a refractive error. If the astigmatism correction in the glasses worn is not suitable, prolonged viewing can lead to visual fatigue, eye pain, and accompanying headaches. In this case, a detailed eye examination followed by wearing appropriate glasses is needed to alleviate the symptoms.
