How the Human Eye Functions Like a Camera

The video explains the similarities between eyes and cameras, focusing on how both capture and process images. It details the anatomy of the eye, including the cornea, sclera, iris, pupil, lens, retina, and optic nerve, and describes their functions. The video also covers how the brain processes images from the retina, correcting their orientation. Additionally, it highlights the protective features of the eye, such as eyelids, eyelashes, tear glands, and the conjunctiva.

How does the brain help us see images the right way up?

• By flipping the images captured by the retina

• By changing the color of the images

• By enlarging the images

• By reducing the brightness of the images

What is the function of the cornea in the eye?

• To change the shape of the lens

• To cover the front of the eye and allow light to enter

• To produce tears

• To carry messages to the brain

Which part of the eye adjusts to control the amount of light entering?

• Iris

• Retina

• Optical nerve

• Cornea

What role do rods and cones in the retina play?

• They focus light onto the retina

• They convert images into signals for the brain

• They protect the eye from dust

• They detect black and white and color

How do tear glands protect the eyes?

• By changing the shape of the lens

• By converting images into signals

• By keeping the eyes clean and moist

• By controlling the amount of light entering
