I am giving 4/5 due to customer service and choice of frames at Asda Tamworth. However for quality of varifocals I would give 2/5. There is a reason the price is so good. If you have a strong eye prescription then the basic varifocals offered may not be for you . I myself found there was a large difference in the vision with the basic varifocals which led to constant headaches and the feeling the vision was just not right . I returned to the store who were very good and it was determined I would need the premium varifocals which can still be a cheaper experience than most opticians. This saying you get what you pay for certainly counts in this situation . However the store did everything they could to try and rectify my issue and would still recommend if your script is not complex . Just consider if you would need premium varifocals . I was refunded the cost of my glasses as did not want to take the chance of having the premium varifocals being done and still not right . The premium varifocals are around £190 extra on top of the glasses you choose so average price around £270 which is still cost effective in comparison to other opticians
