I used to like AMO Total until they reformulated it (?with a stronger
?preservative or ?disinfecting ingredient).

Now it stings my eyes and I cannot use it.

I now use another brand, which does not sting, but is not of such good consisteny as Total: the brand I use now is watery, which means that I cannot clean my lenses during the day. Old formula Total was of thicker consistency, cushioning, and I used to be able to clean the lenses and replace.
