Myopia or nearsightedness is a common vision defect in which you can see nearby objects clearly but not those located far away. Myopia may develop gradually or may occur all of a sudden. Myopia can run in families or may occur due to incorrect viewing of television or computer. People affected with Myopia are able to see objects located nearby clearly, but not the ones located far away. Other symptoms are:
• Blurry vision of distant objects
• Headache due to eyestrain
• Need to squint for clear view
• Difficulty in driving
HOW IS MYOPIA DIAGNOSED?
A condition related to ophthalmology, myopia is diagnosed by a thorough eye examination by an expert in refractive conditions of the eye.
HOW IS MYOPIA TREATED?
Glasses, contact lenses, or refractive surgery can correct myopia. The most common procedures for myopia are performed with a laser, including:
• Photorefractive keratectomy. Also called PRK , a laser is used to remove a layer of corneal tissue, which flattens the cornea and allows light rays to focus closer to or even on the retina.
• Laser-assisted in situ keratomileusis. Commonly called LASIK , a laser is used to cut a flap through the top of the cornea, a laser removes some corneal tissue, then the flap is dropped back into place.
• Corneal rings. Plastic corneal rings, called Intacs, are implanted into the eye to alter the shape of the cornea.
DID YOU KNOW?
There is also the possibility of controlling myopia by using bifocals, progressive lenses and gas permeable contact lenses for children - thus reducing further damage.
