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.

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.
Altering the shape of the lens to enable light to focus on the retina is called?
This process that produces a focused image on the retina through the bending of light rays is called refraction. To bring near and far objects into focus, it is necessary for the eye lens to make an adjustment through this process as light rays enter the retina.
Objects are brought into focus on the retina by changes in the curve and thickness of the?
Objects are brought into focus on the retina by changes in the curve and thickness of the lens.
The process of sharpening the focus of light on the retina is known as?
Contraction
Why does the retina have to be smooth why not wrinkled?
A retina has to be smooth and not wrinkled so the image that is formed by the lens is in focus at all points. If it were wrinkled, some areas of the image would be out of focus; it is smooth to best reflect the light.
Bending light rays so that they focus on the retina is called?
The bending of light rays so they focus on the retina is called refraction.
Bending light rays so they focus on the retina is called?
accommodation

Where does the lens on a pupil focus light?
Onto your retina. Onto your retina.
Where do images come into focus?
For people who are farsighted, images come into focus behind the retina; for people who are nearsighted, images come into focus in front of the retina.
Where does the light focus on the retina?
The Macula.
Objects are brought into focus on the retina by changes in the curve and thickness of the?
Objects are brought into focus on the retina by changes in the curve and thickness of the lens.
Which term describes the region where vision is sharpest on the retina?
Macula Lutea
The retina's point of central focus?
the fovea.
What part of eye focus's light?
the retina
What is the name of the part the eye which lets you focus on objects?
retina
