"My Don started taking Focalin and started to complain that he could not see the board at school. At first I figured well maybe he is just a kid who needs glasses. His prescription was very low. Now a year and a half later his principal from his school called me because he failed the state eye test with his glasses on he has a 20/50 vision. So I took him back to the doctor and they could not correct his vision with the strongest prescription. Everything is blurry and out of focus, he lost all peripheral vision on both eyes. The doctors first question was "What medication is he on?" So I advised him Focalin 10mg. He advised me to immediately go to the doctor who prescribed it because it is a severe side effect of Focalin. Grrrr"
