Make plans for care at once if you have signs such as loss or dimness of vision, eye pain, discharged fluids from the eye, double vision, or redness or swelling of the eye or eyelid. There is no known prevention for presbyopia, but the focusing problem can be relieved with glasses. Floaters are tiny spots or specks that float across the field of vision Most people notice them in well-lighted rooms or outdoors on a bright day. Although floaters are normal, they may be a warning of certain eye problems, especially when occurring with light flashes. If you notice a sudden change in the type or number of spots or flashes, call your doctor.
Dry eyes occur when the tear glands produce too few tears.
The result is itching, burning, or even reduced vision. Excessive tears may be a sign of increased sensitivity to light, wind, or temperature changes. The lens is normally clear and allows light to pass through. So when a cataract forms, light cannot easily pass through the lens and this affects vision. Cataracts usually develop gradually and without pain, redness, or tearing in the eye.
