Prism Glasses Invented in 1930s for Bedridden Patients With Spinal Injuries

Posts on X show prism glasses that let users scroll phones or read while lying down. One user described them as invented in the 1930s for bedridden patients with spinal injuries. Another post called them a Japanese invention for people too lazy to sit up. A separate reply noted personal use after neck surgery, saying the glasses allowed phone and book access without bending the neck. Multiple accounts shared videos and reactions, with some users saying they would try the glasses for conditions that require lying flat.
