Been in the business for a while now and doing Fresnells pretty regularly for about the last 12 years. My experience with them is that they're successfull about 40% of the time. I'm curious about other opticians experiences with these things and if anyone out there has any tips on: trimming the edges so they don't look like Frankenstein did them, applying them so they don't look like there's a fog on the lens, applying over AR and those types of things. I've tried just about everything. I've somehow wound up the prism guy at a group practice that's just full of MD's that absolutely love the stuff. We use Carl Zeiss labs (What's up Darryl Meister?) but they really don't know any more about them than I do. I've never had any formal training with them beyond the cute little pictures on the box. I've been getting by doing it the way I've been doing them but I still think they should look a lot better. As it is I trim them with scissors, then clean the lenses with alcohol. I then apply the prism to the lens in a sink full of warm water and wait for them to dry. Once dry I shave the excess material off the edges using an exacto knife or similar blade and walla done. That's what's worked best for me, any input on this is appreciated.
