Always be gentle with your makeup products. Don't touch your eyes because it's not hygienic. Because of my ocular rosacea, my eyes are sensitive to sunlight. If that's you, make it a habit to wear sunglasses. Also, the wind can be just irritating because it moves invisible particles in the air. This can cause red, watery eyes too. So be mindful of that too and protect your eyes from the wind with sunglasses.
