I had to send a pair of my glasses to Glasses Direct so that they could do some measurements etc, they sent me a pre-paid envelope and returned the glasses within one day. I have now received my new sunglasses and they are brilliant. The lenses are so clear. I can't wait to wear them on my holiday and driving in them is great. Thank you for the excellent customer service both on the phone and in the email contact. I have already recommended to my family and friends.
