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.
Could the eye function without the cornea?
No because the cornea helps the eye to focus on objects and keeps dust and germs out of the eye.
How is laser eye surgery carried out?

What must the light entering the eye first pass through?
The light first passes through the Cornea, a transparent layer which begins to focus the light onto the rear of the eye.
What is the role of the cornea and lens?
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.
Which two structures are involved in bending light rays to focus them on the retina?
When bending light rays to focus them on the retina the two structure involved are the air-cornea interface which accounts for about two-thirds of the light-bending process and the lens which accounts for the remaining third but also makes the necessary adjustments to allow the eye to focus on objects at different distances.
Which part of the eye help focus light as it passes through the eye?
