What type of chromosomal mutation is color blindness?
Tritan color vision deficiency or blue–yellow color blindness is caused by mutations in the S cone pigment gene (opsin 1 (cone pigments), short-wave-sensitive (color blindness, tritan) (OPN1SW)) on chromosome 7 at 7q31. 3–q32, and it affects less than 1 in 10000 people (Nathans et al., 1992).

| Frequency | Red–green: 8% males, 0.5% females (Northern European descent) |
Do color blind glasses actually work?
Preliminary research suggests the glasses do work — but not for everyone, and to varying extents. In a small 2017 study of 10 adults with red-green color blindness, results indicated that EnChroma glasses only led to significant improvement in distinguishing colors for two people.
What colors do colorblind see?
Color blindness, also known as color vision deficiency, is a condition where someone cannot see colors normally in both eyes. It represents a group of conditions that affect color perception, including red-green color blindness, blue-yellow color blindness, and blue cone monochromacy.
How rare is it for a woman to be color blind?
Women can technically be color blind, but it is rare. Color blindness in women occurs in a rate of only about 1 in 200 — compared to 1 in 12 men. That statistic means that 95% of people who have color deficiency are men.
