These are square reading glasses with acrylic lenses that block about 40% of blue light while keeping color close to natural. The frame is plastic with fixed hinges, and the lens measures roughly 1 7/8 by 1 9/16 inches in a frame about 5 5/16 inches wide. They suit people who read on screens or paper and want mild blue-light filtering without a strong yellow tint. Against typical reading glasses, the blue-light filter and square shape are the main differences; the fixed hinges and plastic build are simpler than spring-hinged frames.
