Okay but don't preservatives generally protect from bacteria growing in bottles like this?

Doctors don't want you using preservatives if you have chronic dry eye.

The bottle valve is designed to prevent airflow into the bottle and thus contamination. What makes the bottle a pain is that the valve can make it difficult to get the drops out.

Yeah. I've tried a few different brands and I settled on Bio True because it's the easiest to get out without having to squeeze squeeze. And it's also cheaper in 2 packs, and get a few recurring deliveries on Amazon. I go through about 1 a week or two. I have to take glaucoma drops for high eye pressure and those do contain BAK Gonna try to switch to a different type without BAK.
