Power of accommodation of the eye is the ability of the eye lens to:
AChange its colour
BChange its size
CChange its focal length
DChange its position
Answer & Solution
Correct answer: C. Change its focal length
1. The ciliary muscles around the eye lens can squeeze or relax it.
2. Squeezing curves the lens more, decreasing its focal length.
3. Relaxing flattens it, increasing focal length.
4. This adjustment of focal length is the power of accommodation.
5. So the answer is changing focal length.
