Question
The corrective lens for a hypermetropia eye is ____.
- Of positive power
- A convex lens
- Capable of bringing back the near point to 25 cm from the eye
- All of the above
Hint:
A lens is an optical device that spreads light rays by refraction. There are two types of lenses: concave lenses and convex lenses. A single lens is made up of one lens, while a compound lens is made up of multiple lenses.
The correct answer is: All of the above
The correct option is d) All of the above.
- Hypermetropia can be corrected using a convex lens of a suitable focal length. Convex lenses are of positive focal length and they bring back the near point of a hypermetropic eye to 25 cm.

What is the eye defect shown in the picture below?
The correct option is a)Myopia.
- Nearsightedness or myopia is an eye condition caused by a refractive error that causes distant objects to appear blurry. A nearsighted person can clearly see nearby objects.
- Myopia means that the focus of the eye is in front of the retina instead of on it. The retina is the surface at the back of the eye that collects light.
- It converts light into electrical impulses that the brain interprets as images. Blurry vision can occur when the eye focuses light in front of the retina.
