TheraSpecs Tatum WearOver Light Filtering Glasses for Migraine or Concussion. Lightweight black frames that fit over your prescription glasses, with darker "FL Pro Extra" shade from Theraspecs. Wear them while you work, on top of your regular glasses, helping with light sensitivity from the glare of the screen. (TheraSpecs website says "Its unique design features a modest shelf on top that limits light from above and gently cups your frames—allowing you to pair it with a wide variety of glasses.")
