these are things to remember: Materials, such as pictures, should be simple in form, high contrast (the colors of a picture or object should be different such as a yellow toy against a black background instead of an orange one), and presented one at a time.
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.
It is also important to keep the color of materials constant to avoid confusion. This also applies to visual cues in general which should also be consistent over time and location. If the child uses a red bowl at home and this is how he knows it is time to eat then the same should be done at school. Watch to see if the child has a preference for size or color.
Use a multisensory approach such as pairing an object that you want them to see with a sound.
Touch should be considered as a major sense for learning. Children with NVI appear to learn effectively through this sense.
Repetition and routines can help the child understand their visual environment. If changes are needed make them slowly to allow time to adjust.
Fluctuations in visual performance can be limited by reducing fatigue. Try working in short spurts, or divide a long task into shorter periods.
Reduce outside noise and other environmental stimulation that may distract the child.
Objects can be more easily seen when they are moving. This is especially true when they are in the peripheral fields.
Positioning is also important. The more energy being expended on holding yourself up the less can be used for seeing.
Language helps a child to understand a visual situation by adding meaning to it. Be consistent in the language you use.
