How long have they been expired? I don't see why they wouldn't work, they just might not do as good a job.
I've used expired drops before... I think they got the job done, although I must say, I needed to use them but not because of smoking. They should work though
clear eyes shit expires a month after you open it, fuck that i dont use up that whole bottle in 30days, so after buying new ones 3 times, kept an expired one and lasted be like 3 months, worked like a charm
It's just alcohol and other shit. I dont think eye drops expired unless they're like within a matter of years old.
