Seems it can help.
#1. I'd want to know who underwrote the study and how it was performed.
#2. If they do help, the inherant problem is..........people have to actually ........TAKE THEM
That being said I still do not recommend them to patients. Why? Well seeing as well as they listen to any other advice I give them................
Like this guy who wears disposable contact lenses. Last year I told him to cut back on his wear time and he comes to the office looking like this and his reason for being there? "I want new contacts". Probabaly will have permanent vision loss. Excuse me while I'm not that excited to tell my patients how to take care of themselves !! Oh yeah. We gave him drops to help get him healed up and gave him an appt for the the next day and he is yet to show back up after numerous attempts at calling him. PRobably went somewhere else to get contacts. And this is NOT atypical of contact lens wearers!!!!
