Understanding How Eyes Work

What is the primary role of the eyes in the process of vision?

• To interpret visual signals

• To detect patterns of light

• To create images directly

• To control the amount of light entering the brain

Which part of the eye is responsible for controlling the size of the pupil?

• Lens

• Cornea

• Retina

• Iris

How does the lens of the eye adjust to focus on objects at different distances?

• It moves forward or backward

• It rotates

• It flattens or bends

• It changes color

What role does the retina play in the process of vision?

• It focuses light

• It controls the amount of light entering the eye

• It reflects light

• It converts light into electrical signals

How does the brain contribute to the process of seeing?

• It reflects light back to the eyes

• It combines images from both eyes

• It creates light patterns

• It narrows the pupil
