First time having glasses , they recommended the blue light filter at extra £35 so I paid collected my glasses, when I tried to use them the vision was blurry like I could see shadows if I was reading, so I took them back, they treated me like i was crazy and said there is nothing wrong with the glasses, to me there definitely was, so i asked them to remove the blue filter as the prescription was fine but the filter to me seemed to be put on incorrectly, so they removed the filter but dont want to refund my £35 so now I have to complain to whoever is next in charge to get my money. AM I WRONG???
