i suffered some chemical(little bit of toothpaste and spray) and dust irritation in my right eye before. i suspect whether it has caused dry eye as my right eye does not seem to produce any tears much. though i used lubricant eyedrops, i can't use it always.i have a very tiny bump in the lacrymal gland region of upper eyelid.
i have a doubt. in dry eyes, if lubricant eye drops are not used, what does the eye do to keep cornea moist?does it takes the fat from cells coating it, leading to sunken eyes? i really suffer from sunken eyes suddenly.
please answer my query.
