    Edge Coating Pens

    Does anyone know if the special pens for coloring edges of lenses are just rebranded paint pens? They seem very overpriced.
    Does anyone have any tricks for hiding the clear edge on polarized lenses in more difficult RX's (high plus).

    order a thicker edge? I believe the film is about 1.2mm below the front surface so you can't really knife edge a polarized lens.

    We edge all polar @1.0 bevel, eliminating the need for edge coat.

    That’s what I normally do, but recently did a +6.00 in a patients zyl frame and couldn’t completely conceal the edge without having too much lens sticking out the back of the frame.

    Back in the sixties there was a company named Ancyclo that specialized in very high minus eyewear. Of course they used Zeiss 1.8 lead glass and painted the lens edges with ceramic paint matching the zyle frame color/texture before they heat treated the lens. The resulting edge coating was indestructible - never saw one chip off. We did a -12 with 9D Base Out and the lens edges looked just fine although the poor guys eyes looked like two pi$$ holes in the snow from the front.

    When everyone drank the plastic lens Kool-Aid we used off the shelf marking pens from a craft store.

    Might I recommend Testor’s model paint. They are designed for models made from polycarbonate and acrylics. Plus, they are available in a multitude of colors and sheens.

    Bar none hands down the best edge color pens I've found are made by an Italian company Aurochim. However there is no US distributor and unless you buy a boat load of them they won't ship them to the US. Something to do with the solvents in the markers having a large shipping expense. But, McCray Optical in Canada carries some of them now, and does ship to the US. They are spendy but they work far better and last much longer than any others I've tried.

    I have an art background and to me no pen is worth over $30 a pop but I bit the bullet and bought 2 just to have in the rare case that I need it. The SDS is really similar to regular paint pens...I think I will have to do some tests on some scrap lenses and see if there is any compatibility issues.
