What is the optic nerve?
What is the first structure light enters in the eye?
What is the cornea?
What happens when the lens becomes cloudy?
What is a cataract?
What part of the eye captures light and starts vision?
What is the retina?
Which part carries signals from the retina to the brain?
What is the optic nerve?
Which part of the brain interprets visual signals?
What is the visual cortex?
What controls how much light enters the eye?
What is the pupil, adjusted by the iris?
Which condition is caused by high pressure in the eye damaging the optic nerve?
What is glaucoma?
Which parts work together to move the eye and focus?
What are the lens, cornea, and eye muscles?
Name the transparent structure that changes shape to focus light.
What is the lens?
True or False: The retina forms the final image we see.
What is False? The retina sends signals; the brain forms the image.
What is the name of the process where the lens changes shape to focus on objects at different distances?
What is accommodation?
Myopia and hyperopia affect what part of the vision process?
What is how light is focused on the retina?
True or False: The eye alone creates vision.
What is False? The brain processes the signals.

Name one reason early detection of eye problems is important.
What is to prevent vision loss or impairment?
Which part is a thin membrane covering the front of the eye and inside eyelids?
What is the conjunctiva?
How does the brain combine signals from both eyes?
What is to create binocular vision and depth perception?
Put these steps in order: retina, brain, cornea, lens, optic nerve.
What is: cornea → lens → retina → optic nerve → brain?
Why can vision impairments affect daily life?
What is because they reduce clarity, depth perception, or color detection?
Why is the eye considered essential beyond sight?
What is because it helps learning, communication, navigation, and safety?
