dur ka dekhne ke liye negative concave myopia .pass ka dekhne ke liye postive hypermetropia convex this state ment is true Explain doubt

Answer 1

Heya ☺

Myopia is a defect of the eye due to which the eye is not able to see distant objects clearly. In such eye , the light rays from a distant object , arriving at the eye lens , get converged at a point in front of the retina. This defect can be corrected by using a concave lens of appropriate focal length.


Hypermetropia is a defect of the eye due to which the eye is not able to see nearby objects clearly. This defect arises due to either the focal length of eye lens becoming too large or eyeball getting shortened. This defect can be corrected by using a convex lens of appropriate focal length.




Thanks

Answer 2

dur ka dekhne vale ko myopia kahte hai jisme eye ball bahut long ho jata hai or focal length badh jati hai
pass ka dekhne ke liye hypermetropia use kariya jisme convrx lens hote hai or ya isliye hota hai kyonki hamari focal length kam ho jati hai or eye ball thin ho jata hai. yahi karan hai...
