Due to undetected vision problems, Luci Johnson, daughter of the former President Lyndon Johnson, nearly dropped out of school while her father was in the White House.
After taking nearly every test imaginable, Luci was told she was bright but not living up to her potential. She became so frustrated that she began blacking out during her tests.
It was only after visiting a local developmental optometrist and taking a comprehensive vision related learning exam that Lucy was able to regain her confidence and stay in school. The doctor found that she had tracking and focusing problems that distorted everything she tried to read or write.
Once Lucy completed a course of vision therapy in the doctor's office, her grades went from C's and D's to A's and B's and she went on to become an honor student. She went on to become the head of an organization called Volunteers for Vision and helped screen several thousand children for the kinds of visual problems she experienced.
As she noted in one of her speeches, "if the key to a better society is education, then the key to a better education is better vision. If you don't have that key, you can't open the door to a better life".
