At first with only one
eye I had about 15,000 per day, now with
drops in both eyes they have gone up to almost 30,000 per day. There where no other medication changes during that time. I don't think that the active ingredients cause the problem, but what about the Benzalkonium Chloride (BAK) that is the preservative in the drops, could that cause the problem? has there been any research done on this?
