Well, first, you should know that sore eyes are a very widespread and common eye infection that affects many people. It can be contagious. And if your eyes are infected with sore eyes, the blood vessels in the eyes will darken. Also, your eyes feel itchy, dry and sore, painful and discomfort. To treat it, you can use a clean and warm compress on the eyes for 2-3 minutes for a long time. Also, you should know that an eye pack made from chilled cucumber slices may be very beneficial. Finally, you can put cotton balls dipped in rose water over the eyes for a few minutes. This is very effective in reducing inflammation as well as discomfort. So you can just have a try. By the way, a sore eye can be caused by anything, such as a blow to the face, even something you do not care about. If you have some problems, I will suggest you go and see a doctor and he can give you some eye exam.
