This handy magnifying lens from GodHand is the perfect tool to prevent eye fatigue!

The large 200mm x 130mm lens allows for a wide field of vision and comfortable work. The magnification of approximately 1.8x allows you to see your hand clearly and makes detailed work easier. The large aspheric lens prevents distortion of vision and allows focusing at any position of the lens. If the lens is placed vertically in front of the viewer, it becomes easier to see detailed work, too.
