I got my first appointment with them on Saturday 21st of May (Golders Green) because I was having problems with my vision. I have a pair of glasses and contact lenses with a prescription from Spain, and after the appointment with Specsavers, the optician told me she would change my glasses prescription, for which I paid 90£. I went to get my glass lenses changed on the 2nd of June. I couldn’t try the glasses in the store because I was wearing my contact lenses at that moment and I wasn’t accomodated to remove my contact lenses in the store by the store assistant. I was concerned about not trying them but I was told that I had a month to change the lenses back to my original ones in case the new ones wouldn’t work. When I tried the new glasses at home, I realised that they gave me the wrong prescription: they provided me with glasses to see from closer when my main problem is that I cannot see from far because I have 3 dioptries in each eye. I went back to the store the next day to tell them they provided me with the wrong prescription and I requested them to place my original glass lenses back. The store assistant started doing it in front of me, however, at some point, she went to a private room. The new glass lenses they put in are not the ones that I bought in Spain. First of all, the new lens is thinner and second, my lenses from Spain had a square mark on them. I spoke with my optic in Spain and they explained to me that the square mark is an anagram of the factory where they make their glasses. The lenses they provided me do not have this mark and the store assistant kept assuring me that the new lenses are the original ones, even though she did not change them in front of me. I had to pay 90£ for a prescription that wasn’t right and, apart from that, I do not know what happened with the lenses that I brought from my own country, so now I am wearing glasses that I doubt my prescription is the right one.
