I use this for cleaning out my dog's eyes when he gets dirt and stuff in them, which sadly happens all the time because he digs and kicks the dirt up into his face.
This stuff is a great lubricant for our dog's eyes. We have Cavalier King Charles Spaniels and their eyes get that goobie mucos-like build up. This is a good lubricant for the price. We were buying "people" drops at $30 a bottle. I'd recommend this if you want something other than artificial tears. It's a nice quality.
My 9 year old pug has had several corneal abrasions to her eyes and she sleeps with her eyes open. Her eyes are constantly dry. So in between her medicated drops I use the Hy-Optic Irrigating Solution. This has greatly improved her eyes and she doesn't run into things nearly as much as she used to
