    These glasses are so beautiful! I recently got glasses from a very well known eye doctor all over America. While the prescription is great, the build of the frames are not up to par for the price that I paid for them. I saw an ad online about Yesglasses and thought I’d give them a try. I got such a great deal and when I got them in the mail I couldn’t believe the quality of the frames! Even the case is built beautifully! I highly recommend Yesglasses!

    These glasses look pretty cool, like how they are wide enough for my round face and like the color options.

    These are the BEST quality lenses I've ever had. Crystal clear, great progressive. Better than Warby, better than any other glasses brand I've ever shopped. Highly recommend! I have a pretty small head and these still look cute on me. =)
