If you need an eye exam yes it's different I went in with a prescription it was very easy and in expensive.Insurance should cover your exam just call make an appointment and find out.They are very reasonable with their rates.The last eye clinic I went to took 2 weeks to get 1 pair of glasses.Eye Mart Express had 2 pair done and in my hand in less than 2 hours.
Yes, the left side of the store is where you shop and purchase glasses and the right side is where you see the eye doctor. Both sides have their own door, but you can access both sides from inside.
