Dilation of the pupil
blindsight
Contraction
The cornea is the clear front surface of the eye, which acts like a camera lens, and allows light through to reach 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.
Trick question. Your brain receives an image from your eye that is upside down. It flips it around by itself.
Pupil allows in light. Light reflects off of objects. What we see is transported to our brain by optic nerve. Then we can see ~GrEen <3er 44
Cornea: Transmits & focuses light into the eye. Lens: Focuses light rays onto the retina. Retina: Creates impulses to the brain. Thepupil is a hole located in the center of the iris of the eye that allows light to enter the retina.
Cone cells, or cones, are photoreceptor cells in the retina of the eye which function best in relatively bright light. The cone cells gradually become sparser towards the periphery of the retina.

The sharpest vision on the retina is in the central area. That is where most of the cones are concentrated that have the best detail resolution and respond better when light levels are higher in bright light. There are more rods towards the periphery of the retina. Though they are less able to distinguish detail, they are better at detecting motion and are sensitive at low light levels.

The Retina
The process of seeing green light is a photo-chemical reaction in the rods and cones of your retina.

Rods and cones are located in the retina of the eye. There are more rods than cones, and rods are involved with seeing at night or in low light situations.
