Eyelet Flip is a pair of glasses designed for the widespread condition of presbyopia. Many middle-aged patients experience difficulties with progressive-addition lenses and need to remove their glasses when reading or engaged in close-range activity. With the Eyelet Flip, this is no longer necessary, because the glasses allow wearers to flip up the lenses when necessary. The lens construction is attached to the top bar with a screwless, spring-like hook structure at the centre of the frame.
