The APH Light Box was designed to help teach basic visual skills as well as more complex visual-motor and visual-perceptual skills. The high contrast background created by the Light Box’s illuminated surface makes a variety of visual tasks easier to perform. The goal is that using brightly colored items will motivate students to utilize their vision. The following guidelines are from APH:

The lightbox, available through the American Printing House for the Blind (APH) is used to help develop awareness of light, color, and objects. It can also be used as a tool to facilitate visual tracking, visual scanning, eye-hand coordination, visual discrimination, and visual perceptual skills particularly in students that are interested in light-up objects and sources but will not visual attend to or interact with regularly presented materials. The Light Boxes available from APH have a lighted translucent white work surface with a variable lighting control.

If your student is not eligible for quota funds or for whatever reason those funds are not available, other light boxes or tables can be purchased or even made by placing a string of lights inside a transparent or opaque storage container. Material kits specially designed to use with the APH lightbox can be obtained from APH with quota funds. Although they can be helpful, they don't always meet the unique needs of students and can lack the characteristics that will motivate the student to look or you may just be looking for some variety. The following are some possible materials that can be used with the lightbox.

APH's Lightbox Guidelines

Use the Light Box in a darkened corner of the room, positioned so that other children will not come in contact with it or its electrical cord.
Examine the Light Box for flickering to guard against seizuring in a seizure-prone student.
If a student is seizure-prone, be cautious about presenting items or displays on the Light Box which move in a rhythmic, patterned manner.
If a student is sensitive or averse to light, it may be helpful to introduce the Light Box with overhead lights on.
Use the Light Box in a variety of positions and place the student in a comfortable posture.
Present the Light Box at varying distances and areas in relation to the student’s body and watch him to see whether he demonstrates a preference.
When presenting items on the Light Box, put them in different places on the
work surface. Note whether the student responds consistently and accurately to the items.
Use the colored acetate sheets and objects and observe whether the student prefers one color over another.
Use words like “look,” “see,” and “find” when presenting items on the Light Box work surface. Encourage the student and describe for him what he is seeing – its shape, size, position, and color.
To transfer a skill learned on the Light Box to a normally lit environment, increase room illumination as you gradually decrease the intensity of the Light Box.

Materials for Developing Eye-Hand Coordination

Present a variety of unit related materials (see dry transfer suggestions) in a clear plastic tray positioned over the Light box. Have the student trace with their finger or pour the materials in and out of smaller containers or nesting cups. Possible materials to use on the light box: acetate sheets (clear & transparent colored); colored projection markers; colored grease pencils; finger paints in plastic tray; crayons on thin white paper; three-way mirror; colored cellophane; colored tissue paper; thin, boldly patterned or colored wrapping paper; brightly colored plastic lawn chair strapping; tinsel; plexiglass sample squares; brightly colored or patterned fabric; transparent art film (contact paper); black tape; yarn; colored ribbon; doilies; colored buttons; rickrack; colored or patterned wrapping paper.

Materials for Drawing the Student's Attention to Shape & Tracing Around & Copying Shapes

Cookie cutters; coasters; Jell-O molds; stencils; wooden blocks; parquetry pieces; clay or play dough; poster board shapes; Lauri Tactilmat puzzles; Ideal Tactilmat puzzles; Familiar objects with simple contours (a cookie, ball, bar of soap, shoe, or spoon); puzzle pieces; window clings.

Materials to Use with Lightbox to Develop Skills

Colored transparent plastic construction pieces; colored transparent plastic pegs which fit in a pegboard; clear plastic balls with spinning objects inside; bright colored Teether Ball (projections which make it easy to grasp); rainbow transparent party -ware; Halloween masks; make & bake (colored plastic 'stained glass' ornaments made from simple kit); brightly colored translucent or transparent plastic toys (Easter eggs, pop-beads, etc.); balloons; colored pinwheels; small toy cars; wind-up toys; colored plastic clothespins; plastic Halloween pumpkins; Wikki stick.

Materials to be Sealed in Clear Plastic Bottles

Materials to be sealed in clear plastic bottles to create an interesting object for the student to manipulate over the Light Box: costume jewelry beads; mosaic tiles (transparent plastic squares); marbles; confetti made of colored acetate; colored bath oil beads; fishing "jelly worms" (transparent colors).
