Pricing note
Eye color
A small premium for a very visible trait.
Eye color moves the result only slightly. Green receives the highest adjustment, while blue and brown receive a smaller one. This is intentionally one of the lowest-value variables in the quiz.
Score: green eyes +$10,000; blue or brown eyes +$2,000.
Eye facts
- The eye is made of more than two million working parts.
- A person blinks roughly a dozen times per minute—more than 10,000 times in a long waking day.
- Gray eyes are a light, low-melanin variation of blue eyes and are uncommon.
- Some population surveys have found blue eyes slightly more often in boys than girls, but ancestry explains far more of the distribution than sex.
- Under excellent conditions, the human eye can detect the light of a candle from many miles away.
- Albinism greatly reduces pigment in the iris; reflected light from blood vessels can make the eyes appear pink or red.
Does color blindness mean black and white?
Usually not. Most color-vision deficiency changes how certain reds, greens, or blues are distinguished rather than removing color completely. Different forms of color blindness produce different experiences.
