Your symptoms suggest mild eye irritation or an allergic reaction. I recommend starting with over-the-counter preservative-free lubricating eye drops (artificial tears) 4 to 6 times a day to flush the eye and soothe irritation. Applying a clean, cold compress over your closed eyelid for 5-10 minutes can help reduce the swelling. Avoid rubbing your eye and do not wear contact lenses until it completely heals. If you develop eye pain, changes in your vision, sensitivity to light, or if the discharge becomes thick and yellow/green, please consult an eye doctor immediately for a proper evaluation.
