If I could give this no stars, I would. I ordered the glasses a bit over a year ago and have worn them every day. I recently started having a lot of eye pain, dizziness and feeling sick. Turns out, the glasses I ordered from here are not even CLOSE to the prescription that I sent them. The two lense strengths are the same (shouldn't be) and 0.5-0.75 weaker in both eyes than what is on the prescription I sent them. Tried to get a refund and was told I could send the glasses back, but at my own cost (I am now living abroad, paid the postage for this in the first place and the return would be as a result of their deception, why should I?) and that the refund wasn't guarenteed anyway. Complete waste of money, rubbish customer service, just sending you any glasses you could get in a supermarket for a marked up price. And my eye health has negatively suffered because of it. Disgusting.
