ABSTRACT:
A pair of eyeglasses including right and left lenses, each having a top edge having a downwardly extending notch formed into a central portion of each said top edge, the notches preferably being sized to receive a tubular shape of an eyepiece of a microscope or other such optical device. A frame includes lens support structure to be worn over the bridge of the wearer's nose and carries the lenses so that, when the frame is worn in a normal wearing position, the lenses are in optical registry with the corresponding eye of the wearer and define a substantial lower vertical corrected field of vision for viewing objects close up through the lenses and a substantial upper vertical uncorrected field of vision extending upwardly from the top edges of said lenses for viewing distant objects by looking above the top edge of the lenses without repositioning the eyeglasses to utilize said upper and lower vertical fields of vision. The notches are in horizontal alignment with the wearer's cornea whereby the wearer may position the eyepieces within the notches to enable an uncorrected viewing through the microscope when the eyeglasses are being worn in the normal wearing position.
