I have chronic red burning eyes for years now and I always keep eye drops on hand, we live in a polluted environment and the air quality is lacking goodness, it’s not a wonder that we have this ailment. I think that as long as you see the doctor to make sure that there’s nothing else wrong with your eyes, it seems you’re doing this. When you stop using the eye drops the problem comes back and it’s normal because the protection is missing, it’s also good to mention that unless you’re using prescription drops, buy a reputable brand and maybe ask the doctor or pharmacist if it’s okay for you to use, best wishes.
