What is accommodation in the eye?
Changing the shape of the lens to focus light from objects at different distances on the retina.
How do the ciliary muscles change suspensory ligament tension when focusing on a near object?
They contract, reducing tension in the suspensory ligaments.
How does the lens change shape when focusing on a near object?
It becomes thicker and more curved.
How does the strength of refraction by the lens change when focusing on a near object?
The lens refracts light more strongly.
How do the ciliary muscles change suspensory ligament tension when focusing on a distant object?
They relax, allowing the suspensory ligaments to become taut.
How does the lens change shape when focusing on a distant object?
It is pulled thinner and less curved.
How does the strength of refraction by the lens change when focusing on a distant object?
The lens refracts light less strongly.
