this started just a few weeks ago. it used to be that when i used the A/C in my car, my left eye would get all irritated by the dry air. my left eye is still the worst but now both eyes do it. and now it's completely random. all i can do is try and make them water a lot and (if i'm driving or something) do my best to keep them open.
i don't wear contacts or eye makeup. what's going on?
