Myopia and its treatment.

Myopia, also known as nearsightedness, is a common type of refractive eye error. In this disease, close objects appear clearly, but objects that are at a distance, appear blurry.

How does myopia develop?

Myopia develops in eyes that focus images that are in front of the retina instead of on the retina, which results in blurred vision. This occurs when the eyeball becomes too long and prevents incoming light from focusing directly on the retina. It may also be caused by an abnormal shape of the cornea or lens.

Who is at risk for myopia?

Myopia can affect both children and adults. It can be hereditary. People whose parents have myopia may be more likely to get the condition.

What are the signs and symptoms of myopia?

Some of the signs and symptoms of myopia include:

• Headaches
• Eyestrain
• Squinting
• Difficulty seeing distant objects, such as highway signs.

 How is myopia corrected?

Myopia can be corrected with eyeglasses, contact lenses, or surgery
