when tinting a dark gradient lens on a gradient machine, is there a way to avoid the semi circular effect at the bottom of the lenses? As it is I'm bleaching out the bottoms (sometimes unsuccessfully) Very annoying

I think that a shorter stroke on the lift arm, and ensuring the lens holder swings very freely on it's axis is a possible cure for your issue.
You can try finishing the color by hand dipping for ultimate control.
I'll give it a whirl, Thanks!
Found out the semi circles i was getting are cause by bubbles that form between the lens and the lens holder. Wonder if adding salt to my tints would help? Any thought?
Some lens holders are notorious for bubble creation. Try a different one.
Stirring, or agitation creates bubbles, too.........avoid doing this during the cycle, or immediately prior.
Stealth paddling only! You might want to try a product called Hot Topper(if it is still made).
I would worry about salt attacking the steel tank(s). Not a problem with glass containers, tho.Quote:

precisionlab Brilliant idea thanks
Uncut you're right didn't think of that

Is there anyone contemplating doing away with EyeMed?
Yes! Will be official in May!Quote:
