    Need info on lenses for school project

    Hey everyone, I'm trying to find out some general info about a few lenses, and I'm having trouble finding anything, probably because they're such old lenses.

    Sola ED is one of them

    I'm looking for information like powers it can come in, BC's, materials, things like that. If you can point me in the right direction I'd greatly appreciate it.

    Google tells me it was some "occupational trifocal."

    This was a Sola Executive Bifocal lens. Not pretty mind you......but it worked

    You can use this link for info on the lens and others that you may be interested in.

    Itís so simple to be wise. Just think of something stupid to say and then donít say it.

    thanks for the advice, yeah I did a few google searches but couldn't find anything, maybe I wasn't digging deep enough.

    You appear to be talking about an ED trifocal - a flattop reading seg within an exec intermediate zone, with distance above the exec line. Lots of people on this forum know this. I'm curious as to what they saw in this question that I didn't.
