Does anyone out there know anything about the X-CHROME contact lens which will help correct for red-green colorblindness (a condition afflicting around 7% of the male population)? It is single contact lens, either correcting or plano, worn in the non-dominant eye, which only transmits the red end of the spectrum. While wearing it, your binoculor vision allows you to determine colors quite well, apparently. One problem: it is very darkly tinted, so it isn't good to wear under dim light, and you shouldn't wear sunglasses with it. It's been around for over 10 years! Any practical experience out there with one? I can get fitted with one for around $250. Is it worth it? -Neal McBurnett, ihnp4!druxv!neal, AT&T Information Systems Laboratories, Denver
