These are non-prescription square-frame glasses with blue-light-filtering lenses, sold as a set of four in assorted colors. The frames are very light at about 9.1 g without lenses, and the lenses carry anti-scratch, anti-reflective, waterproof and blue-light-blocking coatings. They suit teens and adults who want a cheap, decorative pair for screen time in several rooms or bags. Against single-pair rivals, the draw is variety and low weight rather than optical certification; the 4.5-star rating comes from a small pool of 26 ratings, so treat praise as limited evidence.

With 26 ratings averaging 4.5 stars, feedback is positive but thin. Buyers mostly comment on the light weight and the look of the frames rather than on measured eye-strain relief.
This set includes 4 pairs of non-prescription blue light blocking glasses with square frames. They are made for use at the office and at home, and for reading, gaming and other time in front of digital screens. The design suits women and men and a range of face shapes.
The frames are reinforced metal with durable metal hinges. Adjustable nose guards help the glasses fit both small faces and larger heads. Each frame weighs 9.1 g without lenses.
The lenses block blue light and are meant to ease visual fatigue and discomfort from long periods of web surfing, gaming and working under fluorescent lights. They have an anti-scratch protective film made of transparent optical polyester (PET), an antireflection coating for anti-glare effect, and a waterproof membrane that resists oil stains without changing the optical properties.
