Question

A person with defective eye cannot see closer objects clearly because the image is formed on where?

Answer 1

Hypermetropia:

1. Hypermetropia or far-sightedness is the refractive state of the eye where parallel rays of light coming from infinity are focused behind the sensitive layer of the retina with accommodation being at rest.
2. The posterior focal point is behind the retina which receives a blurred image.

A person with defective eye cannot see closer objects clearly

1. From the above figure, we will analyze how near objects or things appear to the human eye so that it is unable to perceive them clearly.
2. When any person cannot see a close object clearly, this imperfection or problem of vision is known as hypermetropia or far-sightedness.
3. In these cases, the focal length of the eye lens cannot be shortened in order to concentrate on the light from close-by things onto the retina.
4. The light rays from the nearest object meet beyond the retina and form the image beyond the retina, and this problem can be treated with a convex lens.

Hence, a defective eye cannot see close objects clearly because its image is formed beyond the retina of the human eye.
