Anyone that wears contacts knows that you don't need a new exam to get different lenses.the express exam consists of questions and reading letter and that's it. It should cover all contacts, at least all made from the same materials. If I get a prescription from my optometrist and I use it on there I can order any lenses. When I use their exoress exam, they want me to take a new exam just to switch from acuvue oasys to oasys dailies. It's absolutely absurd. Oh but they can recommend a really expensive brand without the express exam. So basically an extra $20 every time you want to try new lenses. Upload a prescription from the eye doctor WITH NO SPECIFIC BRAND MENTIONED and you can get any damn lense you want. Save your money. Don't go to them. I've used several different online contact lense services, and they are by far the most expensive. I only used them for the express exam. I didn't realize they want to scam an extra 20 put of you everytime you want different lenses. It's totally bs
