Coordination

Question 1

What happens to the eye when you look at a distant object

Answer 1

• The ciliary muscles relax
• This causes the suspensory ligaments to tighten
• The suspensory ligaments pull on the lens, causing it to become thinner, tighter and flatter
• Light is refracted less

Question 2

What happens to the eye when you look at a near object

Answer 2

• The ciliary muscles contract
• This causes the suspensory ligaments to loosen/slacken
• This stops the suspensory ligaments from pulling on the lens, which allows the shape of the lens to become fatter, it bulges and becomes thicker
• Light is refracted more
