Walmart Vision Center offers walk-in eye exams, but exams can also be scheduled. The wait is usually short regardless of whether or not one has an appointment, as it is intended to be fast and convenient.
Eye exams at Walmart are generally cheaper than those performed by an independent optometrist,but the selection of eyeglasses and other products is usually more limited at Walmart, especially in regard to higher quality frames and lenses. The eye doctors at Walmart are all certified optometrists who meet the same requirements as any other doctor. However, these centers are usually intended for routine exams rather than treatment of more serious problems.
