Wearing tints has totally changed my son’s life, he no longer has headaches or feels sick after a lot of reading. His English grade at school went up two grades in a term and all his school work has improved very significantly. Listening to him read is, like listening to a different child and his handwriting has improved. The best result of this is that his confidence has doubled in the short time he has been using overlays and his tints. If the government doesn’t think this exists they should come and talk to the parents and teachers of the children involved and they would see what a difference tints make to their lives.
