Which device is commonly used to view distant objects in low vision?

• A. Distance telescope
• B. Stand magnifier
• C. Reading glasses
• D. Pinhole glasses

Answer: (A)

Viewing distant objects clearly when vision is reduced requires increasing the apparent size of far details. A distance telescope is built exactly for this purpose: it magnifies objects at a distance, making street signs, faces, or events easier to recognize from afar. Stand magnifiers are meant for up-close work, enlarging near text or objects. Reading glasses are typically for near tasks or general refractive correction and don’t provide the necessary magnification for distant viewing. Pinhole glasses reduce blur by limiting light paths and depth of focus, but they don’t magnify images; they actually make things appear smaller and dimmer, so they aren’t used for viewing distant objects. So, for seeing distant details in low vision, a distance telescope is the most appropriate device.
