Washington Crown Center has several opticals owned by same company. You are better off to go someplace else.
They are over priced and lack knowledge of the products. The doctor and the store say they are two different places and will not answer any thing they just send you back and forth to different people. They have hours posted and they do not follow them. There prices for exams change after you are there and the discounts are taken only off half the exam price.
The exam takes about 10 mins with the doctor and the other 50 mins with the front desk.
