Naturally, they want to give you as much information as possible through their site, website or Facebook, but they would rather just do it in a personal conversation. They will keep you informed via facebook about new glasses or fashion trends!
Then they, as qualified opticians, can tell you everything you want to know, over a cup of coffee, about glasses fashion, lenses, eye deviations, prisms etc.
Or if it suits you better they come to your home.
