What is Myopia?
Myopia is referred as nearsightedness wherein a person can see near objects clearly, but has difficulty seeing distant objects. It is usually cured by the eye care professionals by using corrective lenses like glasses or contact lenses. The corrective lenses usually have a negative optical power. It means, they are concave in shape and reimburse the excessive positive diopters of the myopic eye.
Sometimes, a corrected refractive surgery is also advised by the health care professionals. This surgery involves risks and side effects. But it can be applied when the defect is acute, as it affects the general well-being of a person.

How is Myopia Classified?
Myopia is classified in various ways. It is mainly classified into ‘axial myopia’, that is when the eye is too long and as ‘refractive myopia’, that is when the cornea has too much refractive power.
Myopia is also classified as per its clinical appearance. It includes a simple myopia, a degenerative myopia, nocturnal myopia, pseudomyopia, index myopia, Nearwork Induced Transient Myopia (NITM) and the induced myopia.
Sometimes, myopia is measured in diopters. Here, the strength or the optical power of a corrective lens focuses distant images on the retina. The degree or severity can be classified as low myopia, medium myopia or high myopia.
The age at onset also helps to identify myopia. It classifies the defect into: A congenital myopia that is present at birth and continues through infancy. The youth onset myopia normally occurs around the age of 20, while school myopia appears during childhood. Adult onset myopia happens between the ages 20 to 40 and the late adult onset myopia crop up after age 40.
