I dunno if that would help much for dim lights, but it seems plausible in general. (Of course, it’s gonna look a bit odd to other people!) Viennetta #29: Yes, you are a carrier, but Hudson is wrong: Your sons have a 50% percent chance of being color-blind. Assuming your husband is not color-blind, your daughters have the same 50% chance of being carriers(*). This applies to protan or deuteran types, tritan color-blindness is not sex-linked. By way of illustration, my father was color blind; This implies that his mother was a carrier. I, being male, am unaffected (as my children would be, if I had some), but my sisters are carriers, and only one of my two nephews is color-blind. (*) Actually, if he is color-blind, they still have a 50% chance of being carriers, but if they're not carriers, they'll be color-blind rather than normal. Seth #1, Daniel #2:

As a new driver I have concerns about his ability to react when he is unable to distinguish between a blinking yellow light and a blinking red light. There is also the issue of right of way on the water at night with the red and green lights on the bow of a boat. I see some discussions about tinted lenses and some rather significant side effects. Looking for suggestions. Thanks. My son cannot distinguish between the red and yellow lights on the back of a school bus, nor the red and amber lights at a traffic light.
