I'm wanting to buy some new glasses. I'm primarily a contact lens wearer, but have a back up pair of glasses, but they are now super dated and scratched. I've always had what specsavers calls 'thin and light' lenses as my prescription would mean the lenses would be really thick. Specsavers charges an additional $120 for this. Does anyone know of a place that offers a better deal for thin lenses? Any codes or deals?
