upside down glasses - EXPLAINED
gentlemen - upside down glasses are the NUTS. explanation, when you take a normal pair of glasses and set them upon a flat surface you will notice that there is a larger seeing surface below the BOWS than above, then notice that the BRIDGE of the FRAME is normally round. instead of you nose fitting up into the bridge of the frame - by turning upside down - your Nose will now be resting underneath the inverted curvature of the bridge, lifting the largest part of the lense. if you have a very strong prescription the other glasses require a large blank for your frame, resulting in heavy COKE bottle glasses that are heavy and uncomfortable. try this you will not be dissapointed. JMB ps, the lenses have to be switched from left to right, because you are going to be seeing out the right side of the frame with your left eye and visa versa with your right eye. THE nuts for glass wearers.
