Exam points
- Explain near focus: ciliary muscles contract, ligaments slacken, and the thicker lens refracts more.
- Explain distant focus: ciliary muscles relax, ligaments tighten, and the thinner lens refracts less.
- Draw a thicker near-focus lens and rays refracted to converge on the retina.
- Explain why overstretched suspensory ligaments prevent lens flattening and distant focus.
CAIE IGCSE Biology 14.2.6 Accommodation to View Near and Distant Questions 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 ;
