How to solve the problem that sweat flows into your eyes when running?

Hello. When running, you will sweat a lot, and the sweat on your forehead will often flow into your eyes, especially in summer. When running, you will sweat and drip down, and the sweat flowing into your eyes will continue. Sweat contains a lot of heavy metal ions besides saline-alkali components. Sweat flows into the eyes and stimulates the mucous membrane on the surface of the eyeball, which is very uncomfortable. Sweat that needs to be wiped off frequently in the eyes when sweating for a long time not only affects normal running, but also often causes conjunctival inflammation. Therefore, preventing sweat from entering the eyes during running is a problem worthy of attention for long-distance runners and marathon enthusiasts. In my running practice, I found a simple and effective method, that is, before running, I applied erythromycin eye ointment to the four corners of my inner canthus and rubbed it evenly on my eye surface with my hands. Then apply erythromycin eye ointment to the eyelid above the eyes (that is, under the eyebrows) (the applied area is wider than the eyes) and wipe it evenly by hand. In this way, even if there is more sweat on the forehead, it will bypass the area where erythromycin eye ointment is applied and flow down from both sides of the eyes. I do this before every run, and sweat hardly enters my eyes. There are two kinds of eye ointment: erythromycin eye ointment and chlortetracycline eye ointment. Why choose erythromycin eye ointment? At first, chlortetracycline eye ointment was used more. Later, it was found that chlortetracycline belongs to tetracycline family, which is slightly more irritating to eyes than erythromycin eye ointment. Erythromycin eye ointment is soft, so I use erythromycin eye ointment more now. Now I recommend this method to everyone, and interested runners should not try it. I wish you all the best, health, happiness and happiness. Please adopt it. Thank you.
