The Blue Light Blocker Computer Glasses UVR9105-A are non-prescription glasses meant for screen time. They use acrylic lenses in a plastic frame with spring hinges and block about 40% of blue light while keeping color close to natural, so documents and photos don't turn yellow. The frame is small: about 5 1/4 inches wide with a 53mm lens, which suits narrower faces and teens better than broad ones. Against rivals that block 50–90% of blue light, the 40% figure is modest, but it avoids the heavy amber tint those stronger pairs show.
