Myopia is commonly known as "short-sightedness." A person with myopia is able to see close object clearly but objects in distance will appear blurred.
When normal eye look at an object, light rays from your eye enter our eye. These light rays are bent at the cornea and the eye lens before forming an image on the inner layer of the eye called retina. This image is than transmitted by nerve signal to the brain. The brain interprets this signal so that we see the object.
if the light ray are focus directly on the retina, we see a sharp image. Therefore, myopia may occurs when the light ray from distant objects are focus in front of the retina instead of on it, resulting in blurred image on the retina. This is usually because the eyeball is too long or sometimes the cornea and the lens do not bent the light ray properly.
