When you buy a pair of reading glasses You decide how thin the wire frame should be? Does it curve gently around the eyes? Does it hold the bridge of the nose firmly but gently? Is it light enough to be there and not there? Does it make your face look intellectually alive? Can you spend many hours reading with it? Will it leave tired half circles below the eyes? Is the glass case small and stylish enough To fit in your coat's breast pocket? How expensive is it? And will it last long? Obviously you understand that seeing is believing!
