I went to Vision Express in Swiss Cottage because they had a great range of frames. I picked the one I loved and thought, while I'm there will get the lenses fitted to them. I wish I had just bought the frame and shopped around for the lenses. (Not the first time I had the same type of lenses, but unfortunately my usual optical shop had to shut down during the second lockdown). At Vision Express, the bill was twice the price I used to pay at my usual optician's. I was silly enough not to stand up and leave. Later on, I called the shop and asked why the bill was so high. The lady explained that shops have different deals with different companies. The lesson to remember from this is, when you find a great frame, get it, shop around, and see if you can find the same type of lenses for a reasonable price.
