Distichiasis
We’re all aware of how much people love their lashes. There are a variety of lash treatments available today, including lash extensions, lash perms, and even lash tinting. There are, however, some people who are blessed with two rows of eyelashes.
Distichiasis is a condition that occurs as a result of some sort of defect. Photophobia, corneal irritation, conjunctivitis, styes, and droopy eyelids are frequently associated with this condition.
Tetrachromacy
Tetrachromacy is a rare eye condition in which color vision is enhanced. People with tetrachromacy are born with four distinct color perception channels, as opposed to the three cones found in the normal human eye.
It is more common in women than in men, according to research. According to a 2010 study, nearly 12% of women have this fourth color perception channel. Tetrachromats are less common in men. And, in essence, this small percentage of the population can see “invisible” colors that no one else can.
