Flat Top Bifocal Lens
Flat-top lenses were used to correct two different eye prescriptions. Bifocals were easy to spot - they had a line dividing the lens in two, with the upper half for distance vision, and the lower half for reading.
Bifocals have two different lens powers that aid in seeing objects at various distances once the aging process reduces your ability to do so.
