Oof, I know many people will have an intuitive reaction of "how can you be so stupid" - but even without seeing issues, I can imagine myself on a bad day with ADHD active to mistake packaging like that, not noticing until it's too late. Add to that, that eye drops are of course often used because of sight issues, and mistaking it gets even easier. The packaging really should change with some regulations that make it harder to mix up.

Another reason why it is so great, that the US currently has the ability to create sane and helpful regulations, with institutions funded to design them and make sure they are followed, right? /s
