Sweat can burn your eyes because of its salt and acidity, and because it can move other irritants into your eyes:
• Salt content: The amount of salt in sweat depends on your hydration level. When you're dehydrated, your sweat has a higher salt concentration, which makes it more irritating.
• Acidity: Sweat can be acidic, which can irritate your eyes.
• Other irritants: Sweat can pick up dust, grime, makeup, or other facial products from your hair and forehead before it gets into your eyes.
• Oils and hormones: Sweat contains oils and hormones that can irritate your eyes
