Red/Green Color Deficiency

[Mojo]

I have a customer interested in getting a clip on to help with red/green deficiency problems he has. What color would be best to recommend. I know there's not an outright solution, but wanted to hear ideas. I was leaning towards an orangey brown or maybe something like Oakley's G30 lens.

Try Chromagen. www.ireadbetternow.com They address color blindness as well as other visual issues.

Which is it? Red, or green?

Which is it? Red, or green?

As of now I have only talked to this customer via the phone; his question was "what color do you recommend for red/green color deficiency"?

I assume he has a hard time recognizing both.

It's not even likely to help even if you do determine the type of color deficiency.

In theory, let's say you're somewhat green insensitive. If you filter out all the other wavelengths except green (like you wear green tinted lenses), then you may have better color balance.

I don't know of anyone using this theory.

I have seen a red lens used on one side, and the with other made clear ......

And the answer is PLAID! With a little duct tape thrown in, cause they will all match to a truly, fully RG guy: Link: to the "expert" of color efficiency in Canuck land......

On the serious side.....no spectacle lens color has worked with even a smidgen of satisfaction.

Facts: (as uncut's mower/mower exhaust rattled brain can exude.)
Approximately 25% of the male population exhibits at least a minor red, or green, or red and green color deficiency.
Tests have shown that some only exhibit a deficiency of very specific shades of red, or green deficiency, or various combinations of both.
You would have to test each individual for their specific shade of.....deficiency.
In order to "excite" the color is only used on one eye, to contrast.
A firm contact lens, called the X-Chrome lens was used years ago. Cosmetically, it appeared as if one pupil was blown. Spectacle acceptance is nil.

I am not aware of any colored lens, used on both eyes, actually improving color perception. We all know about the X-Chrom contact lens, or red lens, used on one eye to be helpful, but nothing works if used equally on both eyes.

X-chrom won't work in spectacles due to the Pulfrich effect, besides it looks ridiculous.

I wonder if a Drivewear lens would make any difference? I have no data to base that on, but it's supposed to increase contrast for red/green shades. Maybe I'll try it with my youngest and report back.
