Children with NVI experience problems with specific types of visual tasks. They may also be visually inattentive, not wanting to look at objects, and may prefer their sense of touch. Seeing with NVI can be compared with trying to listen to one voice in a noisy room or to speaking a foreign language. For vision stimulation to be effective it needs to happen in everyday real life situations, not only in therapy sessions. Identifying colors in an activity, visually tracking their classmate as they move across the room, and identifying the shape of every day objects are examples.
Bright lighting can help a child see and attend to visual materials more consistently.
Adjust the light both natural and artificial to determine what is best. Controlled incandescent lighting may be better than fluorescent lighting. Give the child time to respond to the materials that are being presented. Color vision is usually intact, and color can be used effectively. Yellow and red are possibly easier to see and can be used to outline numbers, letters, or pictures, to color code, or to attract attention to something you want the child to look at.
