Just bought a new pair of glasses with a 1.6 lens free, was very happy until i went to collect the glasses and discovered the lenses were very thick!!! Staff at wimbledon branch tried to justify it... being wearing glasses for the last 40 years and prescription is the same Suspected thicker lenses were used.decided to order 1.67 thickness for an extra 20 pounds.will collect next week but i told them i expext same thickness as the ones i have. Specsavers used to be very good but recently they are being very greedy using cheap misleading marketing techniques.i will post again when i get the 1.67 lens.
