Blue Light Blocking Glasses Rectangle Full Rim vs Rectangle Full Rim Blue Light Glasses

Both are black rectangular full-rim acetate frames with blue-light-blocking lenses and AR coating, so the choice comes down to fit and lens extras. The 201974 is the more feature-loaded pair: photochromic gradient lenses, UV400, a zinc-reinforced frame and a 0.5 magnification option. The 201996 is the simpler unisex frame with a single bridge and standard AR blue-light lenses. Pick the 201974 for outdoor-to-indoor wear and a slightly built-up frame; pick the 201996 for a plain everyday pair that suits any face.

• Choose the 201974 if you want lenses that darken outdoors, UV400 coverage and a sturdier zinc-and-plastic frame.
• Choose the 201996 if you want a straightforward unisex rectangle with AR blue-light lenses and no tint or magnification.
