Unfortunately, I cannot recommend Optical Visions services. They gave me contact lenses and did not even bother to write which one was right and which was left on the box, or to offer me a copy of my prescription so I could do their job and find it myself. I regret the money I gave them for my glasses and contact lenses, and am only thankful that I did not buy the sunglasses I was planning to from them yet - now I certainly will buy them from a reputable company.
