Question

Myopia is caused due to excessive curvature in cornea. [True/False]

Answer 1

SoluTion :

⏭ Myopia is caused due to excessive curvature in cornea. (TRUE)

$\bigstar\:\boxed{\bf{\pink{\large{MYOPIA :}}}}$

✈ Myopia = short-sightendness

✈ In it distant objects are not clearly visible. i.e. Far Point is at a distance lesser than infinity and hence image of distant object is formed before the retina.

✈ This defect is (i.e., negative focal length or power) which forms the image of distant object at the far point of patient - eye.

✈ So that in this case from lens formula we have

$\sf\dfrac{1}{-F.P}-\dfrac{1}{-(distance of object)}=\dfrac{1}{f}=P\\ \\ \sf\:And\: if\: the\: object\: is\: at \:\infty\\ \\ \sf\:P=\dfrac{1}{f}=\dfrac{1}{-F.P}$

Where F.P is farther point of eye.
