those who started to have it recently, try to peel and cut onion/shallot. no need to do excessively until your eyes sting. just normal cooking amount once a day or once every 2 days is enough.

those who have longer might see it reduced after some time.

ugh... can't you tell this is old wives tales? nobody can prove it, yet it might works for some, or simply a coincidence if it even work.

and do not ever ask back like this when older people tell you something ridiculous like this. it just plain rude to them. just smile and tell yourself they are just plain stupid believing something like this when all the doctors in the world already said there is no cure for it, even with that magic russian eye drop.
