How to Keep Eye Contact in a Nudist Colony

We sent a group of non-nudists to a nudist colony and filmed where they were looking when they were introduced to new people. All the non-nudist men reported that they had trouble resisting the urge to look down and the video replay showed how obvious it was when they did look down. The women said they did not experience these problems and rarely was a woman filmed intentionally gazing towards the nether regions.

This is because men are equipped with a form of tunnel vision that makes them far better than women at seeing directly in front of them and over long distances for spotting targets. Most men's close range and peripheral vision is far poorer than women's, however, which is why men have difficulty seeing things in refrigerators, cupboards and drawers.

Women's peripheral vision extends to at least 45 degrees to each side, above and below, which means she can appear to be looking at someone's face while, at the same time, she is inspecting their goods and chattels.

... A woman's wider-ranging peripheral vision allows her to check out a man's body from head to toe without getting caught. Male tunnel vision is why a man will move his gaze up and down a woman's body in a very obvious way. This is also the reason why men are constantly accused of ogling women's bodies at close range but women are rarely accused of the same, even though research shows that women do more of it than men. It's not that men are bigger oglers than women - men's tunnel vision means they keep getting caught.
