Warning signs of diseases:

The following symptoms may indicate a serious eye disease:

1. Light flashes: These bright flashes, usually in the peripheral vision, may be the first sign of a retinal detachment.
2. Floaters: Small black dots that dart around in our vision are usually not a problem, but it can indicate a serious problem of the vitreous gel or the retina.
3. Pain in or around the eye: This may indicate eyestrain, inflammation or glaucoma.
4. Sensitivity to bright light: This may be due to early cataracts, viral disease of the cornea or refractive errors ( nearsightedness, farsightedness or astigmatism ).
5. Excessive tearing: This can be caused by allergy, blocked tear duct or relaxation of the lower eye lid.
6. Continued redness: This is usually insignificant, but could be caused by glaucoma, episcleritis or iritis.
7. Blurred vision: This may be due to early cataracts or injury to the cornea.
