ABSTRACT The present invention relates to a pair of bifocal eyeglasses, which has a means to elevate the frame from a normal position, to an elevated position. This would allow as nearsighted person to use the reading lens to see overhead or elevated objects, clearly and comfortably, without putting a strain on their neck. This is accomplished by attaching a small shaft with wire legs of equal length, to the frame bridge. At the end of each leg is a nose pad which rests on the person's nose brige. To move to an elevated position, support and lift the frame bridge, with the index finger, and then push with a light motion toward the centre of the eyebrows. To return to normal position, simply press down lightly on any part of the eyeglass frame. The system and construction is simple, and easy. These days when big lenses and close rims with a single frame bridge are most appreciated, along with thin materials and light weight, this invention would most definitely be suited.
