Why is the image inverted in the eye?
The images we see are made up of light reflected from the objects we look at. This light enters the eye through the cornea, which acts like a window at the front of the eye. Because the front part of the eye is curved, it bends the light, creating an upside down image on the retina.
What controls the amount of light entering your eye?
Pupil: The pupil is the opening at the center of the iris through which light passes. The iris adjusts the size of the pupil to control the amount of light that enters the eye.

Which structure of the eye is responsible for detecting light?
retina
What are the four parts of the eye that refract light?
Which four parts of the eye bend and refract light? Cornea, aqueous humor, lens and vitreous humor27.
What two structures light the eye?
The cornea, the front transparent layer of the eye, and the crystalline lens, a transparent convex structure behind the cornea, both refract (bend) light to focus the image on the retina.
What is the name of the mucous membrane that lines the eyelid?
Conjunctiva. The conjunctiva is a clear mucous membrane that covers the inner surface of the eyelid and the outer surface of the eye. The conjunctiva secretes a watery fluid (mucus) that helps lubricate the eyeball and keep it moist.
How does light pass through the eye pupil lens retina quizlet?
Terms in this set (10) The light rays are bent as they pass through the curved surface of the cornea. 2. Then, light passes through the transparent aqueous humor and moves to through the pupil. Note that light does not pass through the iris.
Do light rays that pass through the eye diverge?
The light rays that pass through the eye diverge. The light rays that pass through the eye converge. In bright light, the iris makes the pupil larger to allow more light to enter.
