Question
The power of accommodation of the eye lenses is hampered when _____.
- The ciliary muscles become weak
- The iris becomes weak
- Retina is damaged
- Optic nerve is damaged
Hint:
It is connected to the lens which helps it to change the focal length.
The correct answer is: The ciliary muscles become weak
The correct option is a) The ciliary muscles become weak.
The power of accommodation is the ability of an eye lens to change its focal length according to the distance of the object to be seen from the eye. This is done by the ciliary muscles. When the ciliary muscles become weaker, the power of accommodation of the eye is reduced.
