The nearest distance at which an eyes focus image clearly. of an object. It is 25 cm from the eye.
Q. Which part in the eye provides the most of refraction of the light entering the eye?
Ans:There are several advantages of our having two eyes instead of one. It gives a wider field of view. A human being has a horizontal field of view of about 150° with one eye and of about 180° with two eyes. The ability to detect faint objects is, of course, enhanced with two detectors instead of one.
