Foldable Attachable Front for Eyeglasses
Abstract:
A removable attachment for eyeglasses. The attachment is held to the parent eyeglasses by magnets. The bridge of the attachment includes ball joints that allow the attachment to fold for storage while not in use, and also allow the lens units of the attachment to twist about a horizontal line with respect to the bridge thereby enabling the lens units to conform to misaligned parent lenses.
