Eye Care: Myopia
It is a vision disorder caused by the elongation of the eyeball or a refractive error, so that parallel rays are focused in front of the retina. Popularly known as the difficulty for distance.
1. What is it?
By comparing the eye with a camera in a normally sighted eye focuses the image on the retina but in the myopic eye the image is formed in front of the retina.This may be because the eye is too long or that the lens system is too powerful.
2. Types of myopia
There are basically two types of myopia:
- The simple myopia is present from birth and tends to stabilize in middle age without exceeding the 8 diopters
- Myopia opus that begins in childhood or early adulthood and is not stabilized until later.
