can someone check this easy question for me?
I think the answer is B but im not sure if it's just D
Which part or parts of the eye change the direction of light rays to form an image?
both the lens and cornea
the lens only
the cornea only

I can eliminate the iris for you. It's a band of muscles that blocks the light. It's role is not to bend light, even if there is some diffraction at the edges.
I believe it's both, but I have to look more! I think B or D. What do you think? The lens is definitely significant.
This might help, but I can't guarantee its accuracy
if as you say, the lens is significant, then im pretty sure that B is right!
"In the eye, refraction occurs when light passes from the air to the cornea, from the cornea to the aqueous humor, from the aqueous humor to the lens and from the lens to the vitreous humor. Light spreading out from one point on an object can therefore be focused on a particular point on the retina."
