How can long-sightedness be corrected?	Convex lens	100%
What is the function of the suspensory ligaments?	Alter the shape of the lens	0%
What is the function of the optic nerve?	Carries impulses from the recepetors to the brain	0%
How can short-sightedness be corrected?	Concave lens	0%
What is the function of the iris?	Controls how much light enters the pupil	0%
What is the function of the lens?	Refracts light, focusing it onto the retina	0%
What is the function of the cornea?	Refracts light into the eye	0%
What happens to the eye when it looks at a close object?	The ciliary muscle contracts, which slackens the suspensory ligaments. The lens becomes a more rounded shape, so light is refracted more	0%
What happens to the eye when it looks at a distant object?	The ciliary muscle relaxes, which allows the suspensory ligaments to pull tight. This pulls the lens into a less rounded shape so light is refracted less	0%
Why does short-sightedness occur?	The lens is the wrong shape and bends the light too much	0%
Why does long-sightedness occur?	The lens is the wrong shape and doesn't bend the light enough	0%
What is the function of the retina?	The light sensitive part of the eye covered in receptors called rods and cones, which detect light	0%
