Fogging often happens when temperature and humidity differ inside and outside the lenses. Try these practical ways to stop your sports sunglasses from fogging up.
Wipe with Anti-Fog Cloth or Spray
Use a dedicated anti-fog spray or an anti-fog microfiber cloth made for lenses. Apply or wipe evenly on both sides before sports. It forms a thin film that prevents water vapor from gathering.

Adjust the Fit Properly
Avoid wearing the frames too tight against your face. Leave small gaps around the nose and cheeks for air circulation, which helps release heat and moisture.
Choose Well-Ventilated Styles
Pick sports sunglasses with built-in ventilation holes on the frame or lens. Good airflow greatly reduces fog during intense exercise.
Dry Sweat in Time
Wipe sweat on your forehead and cheeks frequently. Excess sweat evaporates and turns into vapor, which is a main cause of lens fog.
Avoid Sudden Temperature Changes
Do not move quickly from a hot, crowded area to a cold outdoor space. Let your glasses adapt to the new temperature gradually.
