ADJUST LIGHTING & REDUCE GLARE
For students that need higher levels of lighting to see best, consider using task lighting. When using task lighting, light directed on the task should come from opposite the dominant hand and directed only onto the task. Other students may be sensitive to high levels of light and the lighting will need to be controlled to assist them in using their vision. Lamps with controls to vary the intensity of light (a rheostat control) can provide the additional or dimmed illumination.

Lighting should be of sufficient clarity to enable the student to see materials and to perform the necessary visual tasks in the most comfortable visual environment.
Depending on the student’s visual needs, lighting may need to be increased or decreased. Any extra light should be diffused and indirect in order to minimize glare.
When talking, the teacher or instructor needs to position themselves so that the student is not looking toward windows or other light sources.
Students who are light sensitive (have photophobia) may need to block out some of the light and glare around them.
Permit students who are sensitive to light to wear a hat or a visor to help reduce glare and visual discomfort.
The ideal situation is for light to be distributed on the visual task in equal amounts from all angles with none of it reflected back toward the face.
Reduce glare from windows and lights, as much as possible (using blinds, shades, curtains, etc.)
Cover shiny tabletops with light-absorbing materials. Also, avoid shiny surfaces on pages, desks, and blackboards.
Yellow filters or acetate can be placed over work (these can be specially ordered or you can use yellow tinted portfolio covers and are available at office supply stores).
When choosing paper, avoid a glossy finish as it can lessen legibility and can produce glare.
* Disperses light evenly over a wide area
* May produce fewer glare spots because
of even lighting.
* Louvers, banners or grills can be placed
over ceiling lights to minimize glare.
* Light remains cool even at close

* May increase glare for those with

* Best used in lamps that focus light in
very specific areas.
* Enhances contrast between print and
background for some.
* Very bright, intense, and white.
* More energy efficient than incandescent.
* Can be too bright for some, causing glare.
* Not for prolonged use; generates a lot of
