Pinhole glasses do not permanently correct vision or cure refractive errors like nearsightedness, farsightedness, or astigmatism; they only temporarily improve clarity while being worn by blocking peripheral light rays to reduce the "blur circle" on the retina. While they can make vision sharper during use—similar to squinting—they significantly limit peripheral vision, reduce depth perception, and dim the visual field, making them unsafe for activities like driving or operating machinery.
