are the glasses half full or half empty? it depends how you see the world i guess. do you see things clearly or is it somewhat misty? do you have optimum vision through the mist or are you a pessimist? to me these gorgeous empty frames are only half so. see your optician, have them glazed over & optimise your fulfillment. fully!
