These are three pairs of plastic-frame reading glasses with acrylic lenses that filter about 90% of blue light while adding roughly 30% color shift. Spring hinges flex at the temples, and the frame is about 5 5/16 inches wide with 52mm lenses and a 13mm bridge. They suit people who read on screens for long stretches and want a spare pair in several rooms or a bag. Against single-pair readers, the set trades lens clarity for convenience: the blue-light coating tints whites slightly, so color-critical work is better served by plain readers. Buyers rate them highly, though the sample is small.
