→ The defect of eye called myopia [ Short - sightedness ] is caused due to :

(i) Due to high converging power of eye-lens ( because of its short focal length ) .

(ii) Due to eye-ball being too long .

→ Myopia is corrected by using spectacles containing concave lenses .

$\bf \underline{Note :- }$

1. The far point of an eye suffering from myopia is less than infinity.

2. The concave lens used for correcting myopia should be of such a focal length that it produce a virtual image of the distant object and the far point of the myopic eye.

3. The whole purpose of using a concave lens is used to reduce the converging power of eye-lens.
