2. Pain.
Like redness, eye pain is fairly common and can be attributed to a variety of factors. For example, if you are not well-rested, your eyes may feel painful, or if something has gotten in your eye, they can feel irritated. Pain can also be a sign of several eye conditions, such as ‘pink eye’, eye strain, a sty, blepharitis, and glaucoma; however, these conditions are usually associated with other symptoms.
For example, with a sty, a bacterial infection that occurs within the glands that surround the base of the eyelashes, you’ll likely notice a bump and the pain will be concentrated around that bump, and with glaucoma, you may experience halos when looking at the light, as well as nausea.
Discomfort and pain within the eye(s) can also be associated with keratitis. If you are experiencing eye pain – along with other symptoms on this list – see your healthcare provider.
