I'm now set up with Chemistrie

Anna Marie from Eyenavision just spent the day with me, and now I'm set up to produce Chemistrie layered lenses.

I curious as to what tips those of you who produce these regularly would give a newbie.

Would you please mind moving this thread over?

Anna Marie does a great job.

Not really a tip, but one of the most important things the guys in our lab look for is to have the correct upsize of the sun lens. Every frame is different. If you upsize too much, aesthetics suffer because the sun lens covers the frame. If you do not upsize enough, you can end up with a gap between the sun lens and the frame that allows light to get in between the two lenses. Getting this to fit perfect and knowing when to use a spacer magnet may be little things but they are really big things to the customer. Sun light that gets behind a sun lens can be very annoying.

Tips:

1. Always start each job with verifying the sun lens magnet offset. Default is -0.4mm, but values for flat lenses and low wrap angles can be -0.2mm. Visa versa, steeper lenses and/or wrap angles may go as high as -0.7mm.

2. The default position of the Rx magnet is 4mm from the center of the magnet to the boxed edge of the lens. Routinely override this value and decrease it to 3mm.

3. Troubleshoot the jobs as follows:

A. Lay/attach the finished individual sun lens with magnet in place over the Rx lens with magnet glued as well. If you magnet offset is correct, the sun lens should be evenly centered around the Rx lens.
Too much overlap to the nasal side? Correct by decreasing magnet offset
Too much overlap to the temporal side? Correct by increasing the magnet offset.

B. With both individual sun lenses in place, measure the distance between the outer bushing holes. Add 3mm to this value, and that is the bridge size you would choose.

That's most of the important stuff.

Here's a tip be nice to Anna Marie she's awesome. ; )

If you size up the lens lenses according to the guides then offsetting the magnets is moot. For bridge size just place the sun lens with magnets on the Rx layer and pick from your stock to see which one matches, no need to over complicate with measuring and offsetting.

Our office has picked a default position for magnets and we stick to it, so that reorders and replacements can be easily done with very little thought and effort. Our office also archives edging jobs so we don't need the patients frames to duplicate the clip. We could custom choose the position of every magnet but the additional layer of abstractions is more problematic then it's worth.

Rimless jobs require routing the surface of the lens so the hardware sits flush, that means ordering the proper lens thickness from the lab. Rimless lens hardware sometimes requires the magnet position to be moved, in most cases I go 0.50mm above datum again to set a standard in our office.

I agree with you on that.
