Astigmatism (for a human eye) can be removed by using

The far point of a myopic eye is $250 \, cm$. What is the focal length of the lens required to correct this defect?

$A$ defective eye cannot see close objects clearly because their image is formed

Assertion : In a movie, ordinarily $24$ frames are projected per second from one end to the other of the complete film.
Reason : The image formed on the retina of the eye is sustained up to $1/10 \, s$ after the removal of the stimulus.

$A$ student studying the similarities and differences between a camera and the human eye makes the following observations:
$I$. Both the eye and the camera have convex lenses.
$II$. In order to focus,the eye lens expands or contracts while the camera lens moves forward or backward.
$III$. The camera lens produces upside down real images while the eye lens produces only upright real images.
$IV$. $A$ screen in a camera is equivalent to the retina in the eyes.
$V$. $A$ camera adjusts the amount of light entering in it by adjusting the aperture of the lens. In the eye,the cornea controls the amount of light. Which of the above statements are correct?
