    Trouble opening Lindberg mechanism

    Hello,

    I've been struggling with these - Lindberg model 9537. They are full rim glasses with a screwless mechanism.

    Does anyone here know how to open them up? Do I need a special tool?

    It looks like a latch. I would think apply pressure and then slip it out. If you look there by the nasal. However, before doing ANYTHING to this pair of glasses. Call Lindberg and ask them specifically how it opens and if you need a tool. Better to ere on the side of caution here.

    No tool needed, index finger on the top nasal of the eyewire just above the bridge and your thumb on the bottom nasal of the eyewire. Apply pressure from the thumb and squeeze the eyewire together. You should "feel" the frame move together and with a little bit of practice the latch will pop open from the bottom pressure.

    I hate to be that person, but if you don't know how to open a Lindberg frame you shouldn't be putting lenses in it. The tolerances for size, and groove specifications are very specific. The lens should also have a silicone gasket installed in the groove. If this is not done, or done incorrectly, it can lead to premature failure of the frame, rotating lenses, and frames that are difficult to open. That frame has been discontinued for over 5 years already, I would hate to see it broken for the patient without being able to replace it due to incorrect glazing.
