The role of the cornea is to take in the rays of light and focus that light to create a picture. The role of the lens is to aid in this focus process as the lens is actually a part of the cornea.

Structure in eye which focus light by bending or changing thickness?
Both the cornea (hard outer tissue) and the lens (farther inside) curve light rays that fall on the outer eye and direct them toward the retina. The lens is adjusted by muscles in the eye, while the cornea has a fixed focus.
Where was the aqueous humor in a dissected eye?
in front of the lens and behind the cornea
Does light enter the eye through the cornea?
It first goes through the cornea, then through the pupil and into the retina.
What are the structures and fluids through which light passes as it travels from the cornea to the retina?
Cornea, aqueous humor, lens, vitreous humor, retina.
What part of the eye is just behind the pupil?
The lens of the eye sits right behind the pupil, which is the aperature of the iris. The lens is what focuses light onto the retina. The cornea (the transparent material on the front of the eye) also plays a role in focusing light.
What is part of the refractory media of the eye?
the structures in the eye that refract light in the eye is the lens and the cornea.

Which part of the eye having the largest refractive index is?
75% is by the CORNEA and 25% is by the LENS
Does astigmatism result from unequal curvatures of the cornea or lens?
Yes, astigmatism is blurred vision caused by unequal curvature of the cornea or lens.
Where was the aqueous humor in a dissected eye?
in front of the lens and behind the cornea
What is a defective curvature of the cornea and lens of the eye?
the defective curvature on the cornea or lens is called Astigmatism
Does light enter the eye through the cornea?
It first goes through the cornea, then through the pupil and into the retina.
What part of the eye that help you see things clearly?
Cornea/lens.
What is the refractive index of the cornea the aqueous humour and the lens?
1.376 for cornea，1.336 for aqueous humour
What do squid eyes differ from cow eyes?
Squid have a false cornea and true cornea and choroid in their eye and cow don't. Also, a sqid's lens is hard while a cow's lens isn't, there cornea is. Hope this helps.
What are the structures and fluids through which light passes as it travels from the cornea to the retina?
Cornea, aqueous humor, lens, vitreous humor, retina.
Transparent optical device?
The cornea (aka lens).
