CAIE IGCSE Biology 14.2.6 Accommodation for Near & Distant Objects
Practise explaining accommodation through changes in ciliary muscles, suspensory ligaments, lens shape and refraction.

- Biology 0610
Exam points
- explain near focus using contracted ciliary muscles, slack ligaments and a thicker lens
- explain distant focus using relaxed ciliary muscles, taut ligaments and a thinner lens
- link a thicker lens to greater refraction so light from a near object focuses on the retina
14.2.6—Accommodation to view near and distant question 1
[Maximum number: 3]
The eye is a sense organ that is part of the nervous system.
Explain why a person is unable to focus on distant objects if the suspensory ligaments become permanently overstretched.
any three from:
ciliary muscles relax ;
suspensory ligaments can no longer become taut ;
lens, is not stretched / remains wide ;
angle of refraction remains unchanged / AW ;
