What would you do if . . . .

[stargazer]

your lab/supplier told you that they would no longer process Plastic/CR39 type drill mounts?

[QDO1]

Plan a:send to another lab
Plan b:do them myself

[chip anderson]

Tell them, I hope you will miss my account as much as I will miss your services.

Both A & B

I haven't sold a drill mount in anything other than poly, trivex, or 1.67 since Hector was a pup.

[Snitgirl]

who's hector? :D

[Chris Ryser]

Any lab that can not drill a decent hole into CR39 lens material is not an optical lab. If they would have some problem with poly, I would say they have not expored all avenues to make a good job.

I have drilled hundreds of holes into glass, even flint glass and there was never a question of not doing a job. Tell them to go back to drill school.

[Jacqui]

Ditto Chris, although I really like Trivex and 1.67 (they're nice to work with).

I have only used CR-39 a handful of times in years. I have even converted all of my semi-rimless patients to "drill friendly" materials! I think more of it being my "duty to warn" than of helping out the lab. I don't want it coming back to me with issues!

[PAkev]

I may be going against the grain but share the sentiments of NOT using cr-39 with drill mounts. You didn't ecactly indicate it but in all fairness I believe the labs biggest beef with CR-39 drill mounts is warranties. Although there are some flolks wearing cr-39 in drill mounts without any problems, there are many (I humble admit to be one) that fail their responsibility to take care of their eyewear properly. Pulling them off with one hand, shoving them into a pocket or purse without a case, attempting adjustments by themself, etc. are a few but often occurences which make drill mounts more vulnerable to breaking. Then complain they are not receiving the expected service out of their eyewear when they become broken.

Like Spex we already only use 1.67, Trivex or Poly.

[Happylady]

It has been years since I have done a drill mount in Cr-39.

[Jubilee]

Our main lab will do Drill Mounts in CR-39 but won't warranty them.

I always tell patients that the Drill Mounts are a much more delicate frame, and personally you get so much more from the other materials for the price (at least in our office). For us the cost between upgrading to poly and a scratch coat are the same.. Hi-index is a bit more. But for the added features, not only thinner and lighter, but also blocking UV, impact resistance, being able to have a warranty on them.. I have not had one patient insist on sticking with CR-39.

Sometimes the only lens available is in CR39, hence I would use another lab on the proviso that they compensate with the edge substance to allow for mechanical robustness. Mainly use Trivex or Stylis 1.67 in drill mounts, NEVER use Poly unless no other alternative.

I drilled plenty of CR-39 pre-grooved semi-rimless. There was no other option. But, today, drilled CR-39 is like a car without air bags and seat belts, like using fans instead of air conditioning, like treating an infection with sulfa drugs instead of antibiotics...

[Cherry Optical]

I would suggest calling me. We'll drill anything, you just have to pay for it. What we have done is charge more for drilling Plastic/Mid-Index lens materials than for Trivex/Deluxe Index, High Index, and Poly.

It was worked well, and more importantly it has reduced our remakes!
