For most people a typical lamp does nothing more then brighten up a room, for someone who is oversensitive visually it can be a deterrent to be in a room, to sit down and concentrate, or even to multi task. Our brains process brightness by relying on our senses to interpret just how bright a light is. If your senses are oversensitive they may interpret a regular table lamp as being overly bright and a florescent light bulb from a classroom as being offensive.
It may appear that the child, youth or adult is simply inattentive, distracted, silly, rude or even a behavior problem when in reality they may be so unable to process the brightness of a light, that their brain does not allow them to process other information at the same time. A simple fix to this is to change the brightness of the bulb, or even change the color. Not every child will require a house full of blue lights or any blue lights at all, the intervention is dependent on how their senses are interpreting brightness. Become an investigator; set up three different stations, one with a regular light bulb, one with a lower wattage, and finally a blue light bulb. Try watching the child's body language in each circumstance:
Lighting at school can sometimes be more difficult, however schools are often able to order blue screens that can act as a filter for the florescent lights. Finding out about the child's sensitivity to light at the beginning of the school year can really help the child combat oversensitivity, giving them more chances to learn.
Do it yourself:
How can you do this at home, and on a budget?
