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

Buy the Beister if you want dedicated screen glasses with a documented blue-light spec and a very light frame. Buy the rectangle 201974 if you want a sturdier acetate frame with a more classic look and photochromic lenses. The Beister is the more focused screen product; the 201974 is the more conventional pair of glasses. Owner feedback on the Beister is mixed at 3.8 out of 5, so expect a comfortable but not premium feel.

• Choose the Beister if you want light, flexible glasses made specifically for long screen sessions, with a stated 99% block of 380-455nm blue light and two pairs in the box.
• Choose the rectangle 201974 if you want a full-rim acetate frame that looks like regular eyewear, with photochromic lenses that darken outdoors and UV400 protection.
