I have a patient who swears that CR39 is the only material that will work for him. Despite that (thinking that he had never tried Trivex before) one of our opticians tried him in Trivex with Zeiss Purecoat AR. He returned complaining of headaches (as was his complaint in years past when trying poly). During this troubleshoot I checked everything I could think of (including putting his new Rx in a trial frame...through which he saw great), and concluded that perhaps going back to CR39 was the only solution. After wearing the remade lenses in CR39 for 2 weeks he returned again. Same issues. Short of a doctor recheck, would any of you suspect AR as a culprit. I just haven't seen AR negatively affect lenses before, so I'm at a loss until he has his recheck.
