I’ve gotten them for the last ten years and they’ve worked great. The eye dr alternates inserting them from top to bottom ducts each time, which is sufficient. I was able to stop using prescription and otc tears and night gel. Last year I only got bottoms done once and it was sufficient for the year. I was going to skip this year but I’ve noticed my eyes getting dry again so I’ll go get them again.
They start off with collagen soft plugs that dissolve fast so you can try them. Dr puts them in with little applicators. It’s only slightly uncomfortable putting them in, really not even noticeable sometimes. Definitely worth a try and beats looking for that tear bottle all day
