What is myopia?
If your vision is blurry at distance, but you can see clearly at near and can perform near tasks such as reading or computer work, you probably have myopia or nearsightedness. In myopia, the light does not focus on the retina; rather, it focuses in front of the retina. It usually happens when your eyeball is long or the cornea is more curved. Myopia can also be inherited. Some people have pathological myopia in which the length of the eyeball increases significantly within a short period. Myopia is a refractive error or focusing disorder. It is not an eye disease.

Complications of myopia
When you have myopia, you are at risk of having retinal detachment. You should see an eye doctor when you notice floaters or flashes of light as you may be having a retinal detachment. Even if you underwent LASIK or PRK eye vision surgery to correct myopia, you might still have the risk of retinal detachment.
If you notice that your child is squinting the eyes or watching T.V. from close, it may be the sign of myopia. Uncorrected myopia can interfere with your child’s ability to succeed at school. You should take your child to an ophthalmologist.
How is myopia diagnosed?
An optometrist or an ophthalmologist diagnoses myopia during a comprehensive eye exam. You will have a vision test and a series of other tests such as autorefractometry, retinoscopy, phoropter etc., to determine the type of refractive errors.
How myopia is treated?
There are several treatment options for myopia. Choosing the best option depends on your life style and preference. If you do the sports, contact lenses might be the better option. You may also think about eye vision surgery (LASIK, LASEK, PRK), if you want to be less dependent on glasses or contact lenses. Myopia is also treated with a procedure known as Orthokeratology. A rigid, gas permeable contact lenses is used to flatten the cornea and you can wear contact lenses less frequently. However, if you stop the procedure, the shape of the cornea goes back to its original shape.
