If you’ve ever tried to figure out whether someone was gay or straight, a Cornell University study claims that the answer to a person’s sexual orientation can be found in the eyes, according to a Daily Mail report.
Pupil dilation is frequently used to track a person’s level of excitement, and scientists say when someone is aroused, their pupils will shoot wide open.
The sex study, conducted by Dr. Ritch Savin-Williams and Gerulf Rieger, included 165 men and 160 women with straight, gay and bisexual preferences who volunteered to have their optical reflexes examined.
Participants were exposed to sexual videos, and the pupils of straight men reacted to images of women, gay men reacted to men and bisexuals reacted to both sexes.
But the results with women weren’t as straight forward. While gay females reacted to images of other women, straight women responded to both.
