Answer 2

Hey dear,
Being a doctor, I'm good to answer this.

◆ Accommodation-
- The ability of eye to adjust its focal length is called accommodation.
- Cilliary muscles are responsible for this power.

◆ Loss of accommodation-
- Loss of power to adjust focal length usually occurs in oldage called presbyopia.
- Initially, we are able to focus with some strain on eyes i.e. asthenopic pain.
- Later, when accommodation is decreased beyond range there is diminution/blurring of vision.

Hope this helps yoy...
