These are five pairs of reading glasses with acrylic lenses and TR90 frames with spring hinges. The lenses block about 40% of blue light with little color shift, so screens look close to normal. The frame is about 5 1/2 inches wide with a 52mm lens width, which suits average adult faces. The five-pack format is the main draw: you can keep a pair at the desk, by the bed and in the car instead of carrying one around. Rivals in this class often sell single pairs with similar TR90 builds, so the value here is spread across several pairs rather than one premium frame.
