Having two red eyes is not as alarming as having one red eye. A cold or conjunctivitis can result in both eyes becoming red. Both cold and conjunctivitis are minor infections that pose no danger to human health. They are self-healing. One red eye, however, could signal a serious inflammation such as uveitis and scleritis. Uveitis is the swelling and inflammation of the middle coating of the eyeball while scleritis is the inflammation of the hard, tough, outer barrier that offers the eye protection.
Though most diseases or conditions that affect the eye are painless, there are some conditions or injuries that result in eye pain. Eye pain can arise from a dry eye, glaucoma, scratched cornea, eye injury or cancer of the eye.
If there is a significant injury to the eye that results in pain or redness of the eye and lasts for more than twenty minutes, it should be evaluated with an ophthalmologist.
Likewise, if there is a persistent discomfort in the eye especially when there is suspicion that a speck or a small particle might have entered your eye, don’t ignore it. Visit an ophthalmologist to check your eyes to make sure there is no foreign particle in your eye. A foreign particle in the eye is likely to cause an infection to the eye if it stays for long in the eye.
Lastly, it is imperative to note that some grave vision problems do not manifest any symptoms at all. Therefore, it is prudent for people — including those who believe there is no problem with their eyes — to get regular eye exams.
