As an indoor sports, badminton tournament are air-conditioned and players rarely sweat into their eyes.
However owing to the intensity of the games and genetic predisposition to sweat profusely on the forehead, many people wears sweatbands in badminton.

And Anders Antonsen of Denmark.
As a person who wears headbands, I can appreciate its uses to prevent sweat from getting into the eyes.
There are 4 types of head gear to prevent sweat from getting into your eyes.
1. Headband
2. Head tie
3. Hair tie
4. Bandana
1. Headband
A cotton version of the wristband that wicks sweats away from your forehead.
Pros: ample absorption
Cons: a bit uncomfortable owing to the tightness of the elastic band's pressure on your skull.
