A solid fit. Streaming means long sessions under bright key lights and multiple glowing screens, often late at night, so glare-and-brightness comfort and evening sleep protection are both genuinely useful. A clear or lightly tinted lens looks clean on camera while cutting screen brightness; an amber lens is better for late-night sleep protection off-stream.
They won't improve your gameplay or reaction time, that's a myth, but they do make marathon sessions easier on your eyes and help you wind down afterward. Add the 20-20-20 rule and matched brightness for the rest.
