Any additional input would help.
A competitor down the way called me about having problems with poly lighten up a/r lenses. He edged a few jobs, and about 3 days later upon dispense, there were stress cracks in the lenses.
I ascertained and recommended the following:
Any other suggestions? I know I should be dancing around with joy that my competition is having problems, but I am a sucker for helping folks out and teaching folks new stuff. I guess I'm a better optician than businessman.
- He's using a dry cut edger...I told him to check blade sharpness/replace with new cutters
- The frames are zyl (square) and he cold snaps so he contends they are not too big...I told him his tracer may be older and may not trace the square shape properly, thus putting additional pressure at certain points on the lenses...sort of like when the patterns we made were a hair off.
- I also recommended the Resolution poly lens...I was told by many on this board that this was a higher quality poly lens that would reduce/eliminate stress cracks...Are there any other brand names you would suggest?
- I also suggested he try trivex, but the power was a -5.00, and the trivex may not be thin enough for the price.
