Eye Conditions Review

What is the function of the ciliary muscles in the eye?

• To control the shape of the lens

• To detect light and color

• To protect the eye from debris

• To maintain the shape of the eyeball

Which part of the eye is responsible for detecting light and sending signals to the brain?

• Iris

• Pupil

• Retina

• Cornea

What is the role of the lens in the eye?

• To provide structural support to the eye

• To focus light onto the retina

• To regulate the amount of light entering the eye

• To produce tears and lubricate the eye

What is the correct sequence of light passing through the eye to reach the retina?

• Lens → Pupil → Cornea → Vitreous Gel

• Cornea → Anterior Chamber → Pupil → Lens

• Pupil → Lens → Cornea → Retina

• Cornea → Pupil → Lens → Retina

What type of lens does the eye use to focus the image on a sensor?

• Concave lens

• Convex lens

• Flat lens

• Diverging lens

What does the eye act like according to the text?

• A camera

• A periscope

What does the eye adjust to let more or less light in when needed?

• The pupil

• The cornea

• The retina

• The lens

What type of lens is a convex lens?

• Diverging lens

• Absorbing lens

• Converging lens

• Reflecting lens

What type of lens is a concave lens?

• Converging lens

• Reflecting lens

• Absorbing lens

• Diverging lens

What happens to parallel rays of light when they pass through a convex lens?

• They diverge away from the lens

• They are absorbed by the lens

• They pass through without changing direction

• They converge at a point called the focus
