Abstract: Eyeglasses are provided that can function both as make-up glasses and reading glasses. The invention provides an eyeglass frame having a left and right lens support. A nose bridge separates the lens supports. A first lens seats in the left lens support. A second lens seats in the right lens support. Each lens is attached to the lens frame for movement from the left side to the right side of the frame and vise versa to mate with the lens on the opposite side. A first lens and a second lens seat in the left and right lens support. In this position, the eyeglasses function as reading glasses. Since the lenses are movably mounted to the frame, the first lens located on the left side can be moved to sit on top of the second lens on the right side. As a result, there will be no lens on the left side and the eyeglasses can function as make-up glasses. Similarly the second lens located on the right side can be moved to the left side to sit on top of the first lens on the left side.

Abstract: A pair of multi-purpose glasses includes a frame body having a bridge portion, two side portions at opposite ends of the bridge portion respectively, two temples pivotally secured to the frame body at distal ends of the side portions respectively, and two movable lenses on the frame body. The glasses allow eyes to see through the lenses, or the lenses can be moved away from vision lines of at least one of the eyes. The lenses can be positioned at two sides of the frame body to serve as a pair of normal glasses. Alternative, each lens can be moved away from one eye to be positioned on the other side of the frame. The glasses can then serve, for example, as a pair of cosmetic glasses, or for applying eye drops.
