i already was seeing a lot of Jason with albinism stuff but there's been a significant uptick in it since the Thalia casting announcement and I wanted to say: please please PLEASE do actual research about albinism if you're gonna make headcanons about Jason being albino. I have already seen so much ignorant and ableist stuff about it because nobody is bothering to do any research and it's really annoying.
There are different types of albinism!!!!! and no i'm not referring to vitiligo or etc. Just straight up albinism there are different types. There are two main types (oculocutaneous albinism types 1 and 2) plus ocular albinism, and then some other types as well that are even rarer. It is also possible to have only partial absence of melanin. (Vitiligo is a form of partial absence/loss of melanin, and often involves loss over time)
Albinism is a lack of melanin/pigmentation. This affects sensitivity to light and UV rays a LOT. Like a lot a lot. (This also applies to vitiligo btw! Melanin protects your skin from the sun, so a loss of melanin even in patches means those areas are more sensitive!)
Skin sensitivity to sunlight does not only apply to when it is sunny out. People with albinism have to take a lot of steps to protect their skin because they are SIGNIFICANTLY more susceptible to sun/UV damage. It doesn't matter if it's overcast, raining, snowing, whatever. They are putting on sunscreen, and they are putting on a lot of it. Sun protection can also come from just covering up. Big hats are also popular choices.
Sensitivity to light also applies in all environments. Transition glasses are common and sunglasses are common.
People with albinism do not have red irises. A lack of pigmentation in irises (referred to as ocular albinism) appears blue, usually a very light blue (less melanin/pigmentation in the eye, the lighter blue it appears). The red appearance comes from more light entering the eye than usual, causing a red eye effect like you see in flash photography except with the naked eye. This can make the iris appear slightly pink/red-tinted and will more often make the pupil look reddish instead of pure black because you are seeing into the eyeball itself and the muscles and veins within it. Not everyone with albinism has blue eyes depending on how much the pigmentation in their eyes is affected, but a lot of people do.
Albinism basically always includes the individual having vision problems, usually low vision or outright being legally blind. They are not completely blind but it is very likely they are legally blind. We're talking very thick glasses (though glasses don't always help because of what causes the low vision), requiring enlarged text, i know somebody who had a little glass block that magnified text underneath it and they used that a lot, etc etc. Depending on severity they may require other assistive devices. Albinism affects the optic nerve, so other eye conditions like strabismus and nystagmus (and more) are also extremely common if not a guarantee (nystagmus is basically always guaranteed).
Nystagmus, for those who don't want to bother googling it, is uncontrollable eye movement in the form of back and forth shaking. Strabismus is when your eyes don't align with each other. These also cause vision impairment.
If you are writing Jason as having poor vision from albinism, he would KNOW he needs glasses. Literally everybody should know he needs glasses/is blind. He would likely be legally blind and would have been pretty much his entire life. He would also almost definitely have other eye conditions as well. (Also rip Jason being raised by the wolves, poor guy is gonna have the WORST sunburn)
People with albinism have different skin tones! And different hair colors! A lack of pigmentation looks different depending on your individual genes and what type of albinism you have! Look up photo references!!!!!
There is also a lot of fetishization of albinism. PLEASE BE RESPECTFUL when you are making headcanons about it, or creating/designing characters who are albino.
Here's a couple of short tiktoks that go over some basic information and other stuff about albinism if visual-auditory learning is more your jam: [1] [2] [3] [4] [5] [6] [7] (Kayla_lud has a lot of videos going over information about albinism)
okay now everybody take your notes and go tweak your headcanons yeah? yeah. okay good.
