A: Vision screenings are required for every school-aged child in Pennsylvania.

If your student is squinting, complains of headaches, or begins to struggle with handwriting, reading or computer work, it’s time to schedule a full appointment. You’ll be amazed at the transformation that 20/20 vision can do for your child!
