This mirror has a 15x extra strong magnifying mirror reversing to a plain mirror. The 15Xtra Strong Supervision 15x side was designed for people with poor close up vision. Adjustable angle for easy viewing. The correct way to use a powerful magnifying mirror is to get up close to your new the mirror, about 3-4 inches from the surface. You then pull back slowly until the image is just perfect for you. A powerful magnifying mirror is designed to help you see tiny details, better than you ever thought possible--even without your eyeglasses! Getting too far away from the mirror will make your image look distorted or you may even see yourself upside down! Getting too close will make your image out of focus. Our mirrors range from 5x right up to 15x magnification. If you wear glasses or contacts, you will be able to see without them in the right mirror. Everyones vision is different, especially as we age, so being able to find your own visual "right spot" is a unique, individual experience.
