As I know, If the size of the frame you received is ill fitted, you can send the glasses back to Zenni to get it inspected. If the dimensions of the frame is incorrectly measured and inaccurately posted on their website, they will issue you a fell refund. However, if they measure the dimensions of the frame to make sure they were accurately posted on their website, they just can give you the store credit. If you do not want to by the other pair with the store credit, you could buy a pair for your family memebers or close friends with it.
