9. Chronic redness.
A little red in your eyes after a long night or from allergies is normal. But if your eyes are constantly bloodshot, or have a constant burning sensation, it could be a sign of something more serious.
Persistent redness can be related to inflammatory conditions such as uveitis, an inflammation of the middle layer of the eye that can be associated with autoimmune diseases such as lupus or rheumatoid arthritis. It may also indicate an eye infection, glaucoma, or chronic conjunctivitis.
10.Severe eye pain.
An eye that hurts, that even blinking does not relieve, deserves urgent attention. Acute eye pain can have several causes, some of which are very dangerous. One of the most serious is angle-closure glaucoma, which occurs when the pressure inside the eye suddenly rises.
You may experience severe pain, nausea, vomiting, and blurred vision with halos around lights. It can also be a sign of a corneal ulcer, optic neuritis, or even a serious infection. If the pain doesn’t go away or gets worse and is accompanied by vision loss or fever, it’s time to run to the eye doctor.
11. Changes in color vision.
Do colors no longer look as vivid as they used to? This change may indicate problems in the optic nerve.
One possible cause is optic neuropathy, often related to diabetes or hypertension. It may also be an early sign of age-related macular degeneration (AMD), which affects the center of the retina. Changes in color perception are not always noticed right away, but if you detect anything unusual, it’s best to consult.
