Floaters are tiny spots or specks that float across the field of vision. Most people notice them in well-lit rooms or outdoors on a bright day. Floaters often are normal, but sometimes they warn of eye problems such as retinal detachment, especially if they happen with light flashes. If you notice a sudden change in the type or number of spots or flashes, see your eye doctor. Dry eyes happen when tear glands don t make enough tears or make poor quality tears.
Dry tears can be uncomfortable, causing itching, burning, or even some loss of vision.
Surgery may be needed for more serious cases of dry eyes. Tearing, or having too many tears, can come from being sensitive to light, wind, or temperature changes. Tearing may also mean that you have a more serious problem, such as an eye infection or a blocked tear duct. Your eye doctor can treat or correct both of these conditions.
