| BINOCULAR VISION- | ability to see an object with both eyes at the same time |
| IRIS- | varies in color and controls the amount of light entering the eye |
| CORNEA- | clear covering of iris and pupil that protects the eye from dust particles and foreign matter |
| PUPIL- | opening in the eye through which light passes |
| TEARS- | saline liquid that washes the eye and keeps the cornea moist |
| EYELID- | large folds/flaps of skin that wipe the eye clean and Eye Notes |
| BINOCULAR VISION- | ability to see an object with both eyes at the same time |
| EYELASHES- | hairs on the eyelid used to screen large objects from entering the eye |
| LENS- | flexible disc shaped structure that focuses the image of an object |
| EYEBALL MUSCLES- | six muscles that are attached to the sides of the eye, they keep the two eyes focused on a single point |
| AQUEOUS HUMOR- | transparent liquid behind cornea that helps keep the corneas shape. |
| RETINA- | the light-sensitive innermost layer of the eye, that contains cones and rods. The image is projected on the cones and rods in the retina and let us see colors and shades of black and white. |
| OPTIC NERVE- | carries signals from the eye to the brain |
| BLIND SPOT- | area of the retina that the optic nerve enters and there are no cones or rods. |
| SCLERA COAT- | tough, white, outer layer of the eye, makes the ball that gives the eye it’s shape. |
| VITREOUS HUMOR- | transparent jello like substance that fills the eye for lens to retina, helps the eye keep its shape |
| CHORID- | middle layer of the eye between the retina and the sclera, contains the blood vessels |
| CONES- | light sensitive cells concentrated near the center of the retina that allow us to see color in bright light |
| RODS- | light sensitive cells concentrated near the outer edges of the retina that allow us to see black and white contrasts in dim light |
