The near point for your myopic uncle is 14 cm. Your own vision is normal; that is, your near point is 25cm. Suppose you and your uncle hold dimes (which are 1.7 cm in diameter) at your respective near points.

Part A

For you, what is the dime's angular size, in radians?

Express your answer in radians.


Part B

For your uncle, what is the dime's angular size, in radians?

Express your answer in radians.


Part C

Do these calculations suggest any benefit to nearsightedness?

Answer #1

Near Point Of Eye:

The near point of the eye is the minimum distance required by the person to see the closely placed object clearly and for a healthy and normal vision person the near point of the eye is equal to 25 cm but when the person is suffering from eye defect hypermetropia the near point of the person is shifted away from the actual point.

Even if the lenses of our eyes functioned perfectly, our vision would still be limited due to diffraction of light at the pupil. Part A Using Rayleigh's criterion, what is the smallest separation between two pointlike objects that a person could clearly resolve at his near point of 23.0 cm with a pupil diameter of 2.25 mm ? Assume that the light has a wavelength of 510 nm . (To get a reasonable estimate without having to go through complicated...

The maximum resolution of the eye depends on the diameter of the opening of the pupil (a diffraction effect) and the size of the light receptor cells (rods or cones) on the retina. The size of the retinal cells (about 5.0 μm in diameter) limits the size of an object at the near point (25 cm ) of the eye to a height of about 50 μm . (To get a reasonable estimate without having to go through complicated calculations,...
