Henry Greene: When macular degeneration, Stargardt’s disease, albinism or many other macula disorders impact central vision, it’s difficult to see detail, read signs, recognize faces, watch TV and even cross the street. If we have reduced distance vision we only have two options: we can move up close enough to see things better or we can bring things closer optically with telescopic devices. Telescopic devices are helpful for the visually impaired, because it makes the image larger, allowing us to see things further away. Telescopes can either be hand held or mounted onto eyeglasses. Hand held telescopes, often called monoculars, need to be brought up to the eye and focused and aimed at what you want to look at. For occasional use, monocular telescopes can be very helpful. However, if there are extended activities you need to be involved in or your hands need to be free, such as driving or using the computer, telescopes mounted into eyeglasses are often very helpful. Telescopes mounted into glasses are called Bioptic Telescopes and they’re available in a range of powers and optical designs. Bioptic Telescopes are mounted to the top of an eyeglass frame and allow the user to look with their regular vision through their regular eyeglass lens and then tip their head down into the telescope eyepiece to get the benefit of a magnified field of view.
