Keep toys and environment simple and uncluttered. Use books with one clear picture on a contrasting simple background. Familiarity and simplicity are very important. Since the color system is often intact, use bright fluorescent colors like red, yellow, pink, and orange. Colored mylar tissue seems to evoke visual responses.
Familiarity breeds response.
Look for toys and activities that motivate the child. Vision is often best stimulated when paired with another sensory system. For example, auditory cues from the handling of mylar may help attract the child's attention. Introduce new and old objects via touch and verbal description. Try different lighting situations to assess optimal conditions for viewing.
