The part of the eye that focuses light onto the retina by changing its shape is the:
ACrystalline lens of eye
BCornea (front surface)
CIris that controls pupil
DPupil opening in iris
Answer & Solution
Correct answer: A. Crystalline lens of eye
1. The crystalline lens is FLEXIBLE and changes its focal length by ciliary muscle action.
2. This is called ACCOMMODATION — the ability to focus on near or far objects.
3. Cornea provides MOST of the bending (~70 %) but it doesn't change shape.
