Interesting, this shows the probably of a child’s eye color based on the eye color of its parents!
For more obscure eye colors….
About 2% of the world has Green eyes.
Amber is a bit more rare, having a yellow-gold tint, with copper/russet undertones. (Sunlight through a glass of whiskey, you know who I’m talking about) (Actually, he has Hazel eyes, but occasionally gets terrific lighting that makes it look amber) Light brown eyes are often mistaken for Amber, but there is a difference - The yellow and orange is far more distinct in Amber eyes.
Violet/Purple eyes are the third rarest. Having Occular Albinism is far more common than full Albinism.
It actually results in super pale blue eyes, but the red blood in their iris will often show through, resulting in a pale purple tone.
It comes with a host of eye-related disorders and sensitivities. (Mostly because there is no pigmentation in the iris, therefore your pupil dilating or shrinking has very little effect on how much light actually enters the eye - Eye damage occurs very easily, and the optic nerve has a harder time developing)
Black eyes are second-most rare, occurring from a Super-melanistic genetic trait similar to Albinism, but on the opposite scale. Many people say that true black eyes do not exist. They argue that black eye color is rather very dark brown color, so dark that it appears black.
Full Albinism resulting in red eyes is the most rare.
Just curious, what about grey eyes? Because one of my friends has grey eyes and I’m not kidding in the slightest.
Gray eyes are the same as blue, genetically speaking.
One theory is that in gray eyes, there are larger deposits of collagen in the stroma, resulting in Mie scattering rather than Rayleigh scattering (which is basically the difference between seeing a blue sky and a gray sky, for an analogy).
The other explanation is that there might be different concentrations of melanin at the front of the stroma.
That stomp walk thing you do to get the snow off your boots.
During the Bubonic Plague, doctors wore these bird-like masks to avoid becoming sick. They would fill the beaks with spices and rose petals, so they wouldn’t have to smell the rotting bodies.
A theory during the Bubonic Plague was that the plague was caused by evil spirits. To scare the spirits away, the masks were intentionally designed to be creepy.
Mission fucking accomplished
Okay so I love this but it doesn’t cover the half of why the design is awesome and actually borders on making sense.
It wasn’t just that they didn’t want to smell the infected and dead, they thought it was crucial to protecting themselves. They had no way of knowing about what actually caused the plague, and so one of the other theories was that the smell of the infected all by itself was evil and could transmit the plague. So not only would they fill their masks with aromatic herbs and flowers, they would also burn fires in public areas, so that the smell of the smoke would “clear the air”. This all related to the miasma theory of contagion, which was one of the major theories out there until the 19th century. And it makes sense, in a way. Plague victims smelled awful, and there’s a general correlation between horrible septic smells and getting horribly sick if you’re around what causes them for too long.
You can see now that we’ve got two different theories as to what caused the plague that were worked into the design. That’s because the whole thing was an attempt by the doctors to cover as many bases as they could think of, and we’re still not done.
The glass eyepieces. They were either darkened or red, not something you generally want to have to contend with when examining patients. But the plague might be spread by eye contact via the evil eye, so best to ward that off too.
The illustration shows a doctor holding a stick. This was an examination tool, that helped the doctors keep some distance between themselves and the infected. They already had gloves on, but the extra level of separation was apparently deemed necessary. You could even take a pulse with it. Or keep people the fuck away from you, which was apparently a documented use.
Finally, the robe. It’s not just to look fancy, the cloth was waxed, as were all of the rest of their clothes. What’s one of the properties of wax? Water-based fluids aren’t absorbed by it. This was the closest you could get to a sterile, fully protecting garment back then. Because at least one person along the line was smart enough to think “Gee, I’d really rather not have the stuff coming out of those weeping sores anywhere on my person”.
So between all of these there’s a real sense that a lot of real thought was put into making sure the doctors were protected, even if they couldn’t exactly be sure from what. They worked with what information they had. And frankly, it’s a great design given what was available! You limit exposure to aspirated liquids, limit exposure to contaminated liquids already present, you limit contact with the infected. You also don’t give fleas any really good place to hop onto. That’s actually useful.
Beyond that, there were contracts the doctors would sign before they even got near a patient. They were to be under quarantine themselves, they wouldn’t treat patients without a custodian monitoring them and helping when something had to be physically contacted, and they would not treat non-plague patients for the duration. There was an actual system in place by the time the plague doctors really became a thing to make sure they didn’t infect anyone either.
These guys were the product of the scientific process at work, and the scientific process made a bitchin’ proto-hazmat suit. And containment protocols!
