I trimmed the lenses myself to fit my swim goggles, and they gave me much clearer vision underwater. It’s surprisingly hard to find regular swim goggles that seal well, and custom prescription goggles can be difficult to return if the fit isn’t right. I’ve been using these stick-on lenses for about 10 days. After swimming for around 15 minutes, they fog up slightly, but overall they’ve worked well for me.
