These are rectangular reading glasses with acrylic lenses and a plastic frame, built with spring hinges and a blue-light filter the maker rates at 90% blocking. The trade-off is color: the lenses shift colors by about 30%, so whites and screens look warmer than they are. The frame is on the wide side at roughly 5 7/16 inches across, with 55mm lenses and 39mm lens height. They suit people who read on screens for long stretches and want one pair for both close work and blue-light filtering; against plain readers, the filter and spring hinges are the extras, while the color cast and plastic build are what you give up.
