This is the white outer layer of the eye where the six extraocular muscles attach.

What is the sclera?

100

This condition is commonly called “pink eye.”

What is conjunctivitis?

100

This term means sensitivity to light.

What is photophobia?

100

These materials make text or objects easier to see by increasing the difference between colors.

What is high contrast?

100

The ventral stream is known as this pathway.

What is "what"?

200

This clear structure covers the front of the eye and is responsible for most refraction of light.

What is the cornea?

200

This eye condition causes increased pressure in the eye.

What is glaucoma?

200

Retinitis Pigmentosa often causes loss of this type of vision first.

What is peripheral vision?

200

Students with nystagmus may need these during close visual tasks.

What are frequent breaks?

200

CVI stands for this.

What is Cortical (Cerebral) Visual Impairment?

300

This colorful part of the eye controls how much light enters to the back of the eye.

What is the iris?

300

This condition causes involuntary eye movements.

What is nystagmus?

300

This type of vision loss creates blind spots in a person’s visual field.

What are scotomas?

300

These tools may help students with low vision by making text or objects appear larger.

What are magnifiers or video magnifiers?

300

This condition is the most common lifelong motor disability and affects muscle tone, posture, and movement.

What is cerebral palsy?

400

These photoreceptors are responsible for color vision, acuity, and central vision.

What are the cones?

400

This emergency condition occurs when parts of the retina pull away from the tissue that nourishes it.

What is retinal detachment?

400

Macular degeneration affects this type of vision.

What is central vision?

400

For peripheral field loss, increasing this can help a student see more area.

What is distance viewing?

400

This CVI behavior explains how clutter can make it hard to find or separate one object from the background.

What is Impact of Clutter and Crowding?

500

This fluid fills about two thirds of the eye and acts as a shock absorber.

What is the vitreous humor?

500

This condition is the incomplete development of retinal blood vessels due to premature birth.

What is retinitis of prematurity (ROP)?

500

Strabismus can reduce depth perception because the eyes cannot achieve this kind of vision.

What is binocular vision?
500

A student with field loss may need visual efficiency training to develop this skill.

What is visual scanning?

500

This CVI behavior refers to the time it takes a person to notice, look at, recognize, or respond to something.

What is response interval?
