An update to this thread about anti-reflective coatings applied to lenses.
I finally got a reply to a question I submitted to 39dollarglasses.com about their anti-reflective coating. I had noted that this was included in their ordering and seemed to be an automatic add-on to the glasses they sold, and I wanted to know if I could opt not to have these coatings applied. Their email reply to me (about ten days after I posed the question) was "no, it is automatic and you can't opt out of having it applied." I guess some customers would like this, but I'm definitely not one of them, so I have crossed them off my list of online eyewear providers. Which is unfortunate, because they had high index progressives (1.67) for $89, a good price. R.
