I used schulze drops for several years. They seem to be able to reduce eye pressure and reduce or stop cataracts. I do it once a day five to six drops in an eye cup for maybe 30 sec or less per eye. Schulz people will not tell you how to use the drops. Do you use the eye cup for 30 sec., or five minutes? I do eye exercises while washing with the schulz eyebright. It does seem to cause irritation and inflammation of eye which could lead to floaters, uncertain. Look into ozone.
