Pinhole Glasses, Vision Training and Retraining Muscles
A listener sent Adam Curry a pair of pinhole glasses to help with eye fatigue and nearsightedness caused by long hours of screen time. The glasses work on the same principle as a pinhole camera, allowing light to focus more clearly without lenses. The product is intended to retrain eye muscles to adjust focal distance, a technique that reportedly dates back centuries but was patented in 1934.
