Lens coatings for Color Blindness

[Slug]

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,

I've never done anything like this in spectacle lenses but I have fit the X-Chrome (red) contact lens on a few occasions. It doesn't help the patient to perceive colors "normally" but it allows them to distinguish between confusing colors better.

Recently we received lenses at our lab with the same coating on it from Color Max which is no longer in business. After investigating a couple of days, I am pretty confident you will not be able to replicate. What we ended up doing was dying the lenses with BPI Deep Red dye #37880. The patient loves them and says he has better color perception with these than the mirror coat.


Good luck!

As far as I know my company is about the only one these days that can come up with any color you need or want, for the optical or any other type of plastic surface tinting. Find it at http://optochemicals.com and or send an e-mail.
