Hi there, A few weeks ago, my wife had an eye test and bought two pairs of glasses from the in-store opticians at Tesco. One normal pair, and one with the type of lenses that darken in sunlight. They were only a very weak prescription, so she does not need to wear them all the time. Ever since she got them she has said that something didn't seem right, but we put that down to her eyes getting used to the new prescription (I know this can take time as I'm a speccy four-eyes myself ). Last week, when wearing the glasses, she noticed when looking at a light, that she could see two lights, and not one. She tried the other pair and these were the same. I tried them on and saw that they were definitely two light sources instead of one - almost like a 'ghost' image. Now obviously when driving at night, this could be very dangerous, as the vehicles coming towards you could be slightly to the left or right of their true position. She rang Tesco this morning and told them about the problem. They said it is because she hasn't got an 'anti-glare' coating on the lenses. When my wife was in the optician ordering the glasses, Tesco never mentioned that there would be this problem if she didn't have the lenses coated. Now, as it stands, the glasses are unsafe at night, and distracting during the day unless you are standing in the shade. Do we have any recourse with Tesco in getting this sorted out? Obviously if they offer to put on the anti-glare coating and charge us for it, that's fine (I wouldn't expect it for free). However if they say they can't do anything about it as the glasses have already been made and they can't put the coating on, would we be entitled to a refund, as they are not fit for purpose? Many thanks, Steve
