KLASSNUM's anti-blue-light reading glasses pair clear polycarbonate lenses with a plastic rectangle frame. The lenses carry an anti-reflective HMC coating and a blue-light filter aimed at screen time. They are sold as regular reading glasses, not progressive or auto-focus lenses, so the "automatic zoom" in the name is marketing rather than a focusing mechanism. Compared with drugstore readers, they add blue-light filtering and anti-reflective coating; compared with prescription computer glasses, they lack a custom prescription and blue-light filter strength rating.

These reading glasses have a rectangle plastic frame and clear polycarbonate lenses. They are made for farsighted wearers and are designed to be used with screens such as a TV, phone or computer.
The lenses set their power automatically to match the wearer's level of farsightedness. They work for powers from +1.00 (100) to +5.00 (500) and are for farsightedness only. The lenses also have an anti-blue light function that blocks harmful blue light from screens, plus an anti-reflective coating.
