Whether you're trying on a tiny fly, stitching an intricate pattern, or just trying to read the fine print, the Carson CP-12 Magnifying Hobby Glasses will be a big help. Magnification is 1.8x, about the same as a 3.3 diopter adjustment. The flip-up lenses are coated to reduce reflection and improve light transmission for a clearer picture, and the coating also provides a durable, scratch-resistant surface. The Hobby Glasses can be worn over regular eyeglasses, and the lenses have a nose bridge for comfort and stability. They come with a hard-sided carry case for protection when not in use.
