Prime retail locations don’t come much better than Harvard Square Optical’s storefront on the outskirts of the famed square. Catering to the student set, who live, study and shop within its bounds, Harvard Square Optical provides eye exams, a wide selection of eyeglasses and shades, as well as, contact lenses. The store owner, Neil Cohen, provides the friendly service without the pestering solicitation. What he will sell you on is the Student Advantage discounts of 15% on all merchandise. The store offers vision exams and takes most major insurance so those frames you have your eye on can be had on a student’s budget.
