We have a BPI tinting unit.
We are struggling to tint stock polycarb HC lenses in house SOLID GREY 3.
BPI advised us to use the Lens Prep II Solution before tinting. We followed the instructions, and we still cannot tint stock poly lenses.
We also cannot tint poly surfaced lenses. Why do the lens have clear transparent dots?? I can send a photo to show you what happened.
Please advise!!!!
