MYOPIA is that defect of human eye by virtue of which it can see clearly the objects lying at short distance from it . but far of the objects cannot be seen clearly by the myopic eyes.

A myopic person has no problems in reading and writing.but he has problem in driving etc.they can not be see distinctly the objects lying beyond a particular distance.this is as if the far point of a myopic person has shifted from infinity to some particular distance from the eye.

The two possible causes of this defect are :-

* increase in the length of the eye ball , as if distance of retina from the eye lens has increased,
*decrease in focal length of the eye lens when the eye is fully relaxed . if the ciliary muscles holding the eye lens do not relax fully and have some tension.

*** concave lens is used in the spectacles of a person suffering from myopia.
