Is anyone familiar with lenses specific to Color Blindness? We have been given a lens sample from a doctor's office to make in a pair of glasses for a patient who is color blind. It seemed simple enough at first but we are not able to match the sample close enough.

The sample is a plastic material tinted light amber in color but there is an iredescent mirror coating which none of our coating suppliers can replicate. The sample (per the doctor) came from a company called Color Max?? which of course (per the doctor) is no longer in business

Any information that you could pass along would be greatly appreciated!

Thanks,
Steve
