I ordered RGP contact lenses from this company through my eye care provider. They lasted a whole 4 and a half months. The first delivery came with a cracked lens and I had to send them back for a second delivery. Typically, these lenses last up tu 3 years. The dot that was supposed to be drilled into the right lens wore off from being cleaned daily. This should not happen if it were drilled into the lens. Now there is a complete layer of film that will not come off the lenses and my right lens is like you are trying to see through a foggy window. My eye doctor called and Essilor states that they do not guarantee their lenses. If I had known this, I would have never purchased them. In all the years that i have worn contacts, I have never had any lenses do this in such a short time. Do yourself a favor and do not purchase this brand of lenses.
