Light perception refers to the ability to detect the presence or absence of light, but without the ability to distinguish shapes or details.

To support individuals with visual impairments in the classroom, it is important to use a combination of strategies such as providing large print materials, audio recordings of texts, and tactile graphics and models.

Visual acuity refers to the ability to see objects clearly at different distances, allowing us to distinguish details and shapes.

Glaucoma is a type of visual impairment caused by damage to the optic nerve, often due to increased pressure within the eye.

Color vision refers to the ability to distinguish between different colors, allowing us to perceive the world in its full spectrum.

To support individuals with visual impairments in the workplace, it is important to provide accessible software and technology, modify job tasks and responsibilities, and provide assistive devices and equipment.
