There are many reasons for sore eyes, most of which are caused by visual adjustment fatigue due to excessive eye use, or due to dry eyes, which can be relieved by reasonable rest. There are two points to be concerned about: 1. For people who are nearsighted and usually do not wear glasses and experience soreness and swelling, it is recommended to wear glasses of the right prescription; 2. For long-term soreness and swelling that cannot be relieved, it is necessary to visit the ophthalmology department of a regular hospital to exclude the increase in eye pressure due to glaucoma, which can also cause soreness and discomfort. The soreness and swelling can be relieved in most people through reasonable rest. If the high intraocular pressure caused by glaucoma causes soreness and swelling, rest will not relieve it and the intraocular pressure must be lowered to relieve it. If the soreness can be relieved in the short term, it is not a big problem, but if it cannot be relieved in the long term, it is necessary to go to the hospital and measure the intraocular pressure, which should be lowered with medication for high intraocular pressure.
