Serious Eye Symptoms to Watch Out For


Eye conditions and diseases: If you have sudden blurry vision in one eye and are over 60, you may have developed a macular hole in the part of the retina where fine focusing occurs. Blurry vision also may be a symptom of a detached retina, eye herpes or optic neuritis (inflammation of the optic nerve), among other causes. Certain eye conditions and diseases can cause permanent loss of vision, so it’s important to visit your eye care practitioner for diagnosis and prompt treatment.


Vision changes such as blurred vision or cloudy vision, as well as glares and night “halos”, may be symptoms of a cataract. If unremoved, cataracts can eventually grow so cloudy that they obstruct vision to the point of blindness. But by replacing cataracts with artificial lenses, cataract surgery is very successful in restoring lost vision.


Blurry vision or “tunnel vision” may be indicative of glaucoma. Symptoms can include a gradual or sometimes sudden narrowing of your field of vision accompanied by blurred vision at the edges of your field of view. Without intervention, vision loss will continue and permanent blindness may result.

Age-related macular degeneration

A gradual loss and blurring of vision, including distortions such as straight lines appearing wavy or broken, could be symptoms of age-related macular degeneration (AMD), a leading cause of blindness among older people.

Diabetic Retinopathy

If you have diabetes, unexplained blurred vision may be due to the onset of diabetic retinopathy, a sight-threatening disease that damages the retina of the eye.

Cardiovascular disease and other systemic diseases

Blurred vision, often in conjunction with double vision, can be a symptom of an underlying health emergency such as a stroke or brain hemorrhage; or it can be an early sign of multiple sclerosis. If you have sudden blurry vision or double vision, see your doctor immediately. If you have some minor blurring that comes and goes, this could mean simply tiredness, over-exposure to sunlight or eye strain. However, sudden or continuing changes in vision such as blurriness, double vision, tunnel vision, blind spots, halos or dimness of vision could be signs of a serious eye disease or other health problems. If you have sudden changes to your vision, you should always contact your eye doctor immediately.
