A study commissioned by Scrivens Opticians & Hearing Care aimed to expose the misconceptions people might have about contact lenses, you know, to sell more contact lenses. Just to keep it interesting, they added some other common misconceptions people believe to see what out there people.

Scirvens' spokesperson said “If enough people tell us the same thing we’re inclined to believe it, and for many of us we will have believed these tidbits of incorrect information to be true since childhood."

Myths about contacts made the top 30, including one about losing your contact behind your eye and another about contacts freezing to your eye during cold weather.

It's funny how supposed facts like, "Humans swallow eight spiders every year," take a life of their own. Like, how would that even be tested?

Ten More Myths We Should Give Up On:

  • Chameleons change color to blend in with their surroundings: Chameleons make small color adjustments, but the real function is to alert neighbors of danger.
  • Sugar causes hyperactive in children: Over a dozen large studies have shown this is untrue.
  • You should pee on a jellyfish sting site: This possibly might even make things worse.
  • Bats are blind: Bats eyes are small with very sensitive vision, helping them see in conditions much darker than we might consider pitch black.
  • Swimming too soon after eating leads to cramps: Mayo Clinic says there isn't a basis for this one.
  • Dogs only see in black and white: They do see some color, though not as bright as we would.
  • Touching a baby bird will make the mom reject it: Moms love their kids no matter what.
  • Shaving makes your hair grow back thicker: This won't change thickness, color, or rate of growth.
  • Cracking your knuckles will cause arthritis: It doesn't do harm to your joints.
  • Going out in the cold will give you a cold: The viruses that cause colds spread easier in lower temperatures, and the exposure to cold and dry air might impact the immune system.
