I had to use an eyewash after the sand blew in my face.
Using an eyewash that is produced to be used as such is safe, if used according to the directions. Homemade eyewashes may be harmful. It is always best to use an approved eyewash.
Eyewash bottles are suitable for use only between the time you get a corrosive chemical in your eye and when you get to an eyewash fountain. Asbestos is not a corrosive chemical. If it gets into your eye, it will not be more damaging than other forms of dust, so there is no need for such a device, and little value.

Eyewash is used to get debris out of the eye. Like if your eye felt like something got into it and it was hurting then you would need to use eyewash or just rinse your eye with water to remove whatever had gotten into it.
