In normal, undistorted vision, the cornea (the clear window in front of the eye) is smooth and equally curved in all directions. With astigmatism, the cornea is "warped", meaning it curves more in one direction than the other distorting or blurring vision for objects at any distance.
Large amounts of astigmatism are usually inherited, present at birth and frequently remain unchanged throughout life. Small amounts of astigmatism can be acquired any time in life and are, in fact, very common.
While hard lenses are usually better than soft lenses for this correction, some special soft lenses may be helpful to correct mild astigmatism. Large amounts of astigmatism are not easily corrected with lenses as it may wobble on the uneven surface of the cornea. In such instances, a toric lens may be prescribed which stabilizes the lens on the cornea.
What kind of first aid options are available for eye injuries ?
Correct treatment following an eye injury can prevent the loss of sight. Medical help should be sought as soon as possible. Call your ophthalmologist, your family physician or go to a nearby hospital emergency room immediately! Specks in the Eye
Never rub your eye. First try lifting your upper lid down over your lower lid allowing the lashes to brush the speck from the inside of the upper lid. Blink a few times and let the eye move the particle out. If the speck remains, keep the eye closed and seek medical assistance. Blows to the Eye
Apply an ice cold compress immediately for about fifteen minutes to reduce pain and prevent swelling. A black eye or blurred vision could signal internal eye damage. See your ophthalmologist immediately. Cuts of the Eye and Lid
Bandage the eye lightly and seek immediate medical help. Do no attempt to wash the eye or remove an object. Never apply pressure and be careful not to rub the eye. Chemical Burns
Flood the eye with water immediately, using your fingers to keep the eye open as wide as possible. Put your eye under a faucet or pour water from a clean container gently and continuously for at least fifteen minutes. Roll the eyeball around as much as possible. Do not use an eye cup and do not bandage the eye. After these steps have been taken, seek medical help. The key to maintaining good vision is prevention. Remember, safety first!
