Greater Latrobe Senior High students in Mrs. Jennifer LeVan’s Human Body Systems class had the unique opportunity to meet with Optometrist Dr. Mark Graytok, of Graytok Family Vision Care, at his Greensburg practice. They learned  about eye exams, eye conditions, and the equipment he uses to examine a patient’s eyes. Students recently covered an eye unit in class and this was a great way to connect the content they learned in the classroom to a real life experience.
