>As with many medical advancements, it is often discovered that a medication or lasers can have multiple uses. When it comes to laser technology, there is now the potential to change a person’s eye color. However, the laser that is in development to change eye color is a completely different laser than the ones used for LASIK
>Can a LASER really Change Your Eye Color?
>In short, lasers can change the color of dark eyes to lighter colors. This is because all eyes are fundamentally the same with the difference being that brown eyes have a layer of pigment on the surface that covers the blue iris. By eliminating the brown melanin, or pigmentation, the eye would appear blue
>Is the Procedure Safe?
>Preliminary studies have shown no safety concerns when it comes to the procedure. This is due to the use of a low-intensity laser. However, this technology is still being evaluated and it is not yet available for commercial use. The main concern is that the pigment could clog the drainage channels as the body eliminates it. This could lead to a rise in pressure that could result in glaucoma

We can change eye color.

Doesn't work?

This. Waste of funding.

doesn't seem unfathomable, but contacts exist even if they are uncomfortable. This is purely a superficial thing, nothing groundbreaking. No use, no purpose.

>>10245981

Seriously though this eye-changing shit is a fucking stupid idea that will not work and would not be worth doing even if it did work.

>>10245956
no thankyou, i find the light eyes black people really uncomforable to look at

>>10245975
It only does blue eyes? That's legit gross. If it could do new interesting colors like purple, red, orange, etc.. then maybe it'd at least be interesting but this is just gross for a whole slew of reasons.

It's a safe form of bodymodding. At the very least, it keeps bored people from doing more dangerous things.

It's also irreversible, so cosmetic surgery addicts can only get it once.

I'm a brown eyed white person, and I can change my hair color with a 89 cent bottle of hydrogen peroxide, but I can't change my eye color. I feel like I'm not white enough.

>Another candidate is the PhotoGenica V-Star Pulsed Dye Laser (Cynosure, Inc., Chelmsford, Mass., USA), with wavelength of 585 nanometers
>In one embodiment, the second iris color does not naturally occur in a human iris

Eye color is caused by light passing through the iris, which is colored with blue-black-brown eumelanin and red-white-yellow pheomelanin. Green eyes have less eumelanin, and a normal quantity of pheomelanin, while blue eyes have less than both. Eumelanin absorbs light energy better than pheomelanin, and this is why they can give you green or blue eyes - less energy/fewer passes of the laser causes more inhibition of the cells producing eumelanin, resulting in green eyes. A repeat of the procedure would change eyes from green to blue.

Hypothetically, you might be able to remove all pigment from the iris, which might reveal purple or red eyes in certain people with very thin collagen.

Orange eyes are extreme amber eyes - lots of pheomelanin, lots of lipochrome. You'd have to be born with lots of lipochrome.

Extreme levels of pheo- or eu-melanin in the absence of the other cause unnatural colors. Another thing to keep in mind is the thickness of the eye collagen - thicker collagen looks grayer, while thinner collagen looks bluer.

Different papers reference different wavelengths - 532nm and 585nm.

>>10246304

I want green eyes with blue rims and brown centers. But I'd take green eyes, or even blue eyes.

I just don't want shit eyes, honestly.

Brown eyes aren't just a layer of pigment over a blue eye. The fine collagen structure of a blue eye is fundamentally different to a brown eyes course collagen structure, no surgery could possibly change that. That is hardcoded by your DNA.

>>10246831

>Brown eyes aren't just a layer of pigment over a blue eye. The fine collagen structure of a blue eye is fundamentally different to a brown eyes course collagen structure

Little melanin in the iris + thick collagen = gray eyes.

The only white population where thick eye collagen is common, causing gray eyes, is in Slavic populations;

Gray eyes are also still light eyes. I don't care if I get gray or blue eyes, as long as they're lighter.

Could this also be used to treat melonoma?

>>10246877

The energy required to inhibit melanin synthesis is much less than the energy required to kill a cancer cell, so no.

Because you believe your skin and eye color are a value of your worth. spend half the money you would need to do this procedure on a therapist.

This.

>>10245956
So this can only remove pigments?
Damn I wanted to have black eyes

>>10245956
So just iris pigmentation?
Nothing of the eye's actual functions?

>>10245975
Lighter eyes might actually have other benefits/disadvantages to darker eyes in nature though. That's probably part of the reason why they exist in nature in the first place.
I remember hearing about a chinese man who mutated blue eyes and could see clearly at night time. Don't know if that's a lie though.

>Because you believe your skin and eye color are a value of your worth

I was born with black hair, and grew it long. No one would look at me, and I was practically a ghost.

I bleached it until it was orange, and now women complement me on my hair.

I'm also an artist, and can tell you that the human eye sees black as a void to be ignored. Brown eyes are the same thing - they're a void people ignore. The attractiveness of brown eyes is that they look bigger and friendlier than blue/green/gray. Lighter eyes look smaller and predatory.

I want light eyes because they're associated with whiteness. I feel as if I'm in the inferior brown room, and want to go to either the blue or green room.

>>10247443

I emailed two companies that supposedly do this and never got a response. I'm not sure if it's because I'm an American or what.

I don't think I could buy it yet. I'm actually more set on doing this myself at home.

A 585nm LED costs less than a dollar. By focusing multiple LED's into a lens, the energy can be collimated into a laser.

1.5mJ is nothing in terms of power, and the effect results from metabolic inhibition of tyrosinase. Thus, simply shining a 585nm light into the eye should work - the final filter before the laser left the aperture would be opaque in the center, and as long as you couldn't see light you'd know none of it would enter the pupil.

>>10247494

Look up eye tattoos.

>>10247531

>So just iris pigmentation?

Yes, just the iris.

>>10247542

I have no idea, but the machines I've looked at for melasma are 80mJ+. The skin is less delicate than the eye.

Being on /sci and thinking "Slavic" means anything more than old cold war era USSR propaganda to "unite the people".

Look it up, none of the considerate Slavic nations have anything in common, besides white skin and most of the time fair hair. Their language, their history, their art history, their religion history its all bullshit, nothing in common. And look up the term itself, when it appears for the first time and what is used for.

Their language is not the same, or have the same root even. So its not, race, its not culture (since their culture is different in every region), its not the combination of the two, its their religion (different again) its not their language, what is it then? Every former USSR country is Slavic now?

>Gray eyes are most commonly found in Northern and Eastern Europe

Most Eastern Europeans who have light eyes have gray eyes, not blue eyes. Of the Eastern Europeans who do, most are Slavs - all the other Eastern Europeans are dark, basically.

Baltics often have gray eyes as well, but they aren't Slavs. I'll admit my original statement didn't include Balts, though - but for the most part, the light-eyed eastern Europeans are Slavs.

>>10247905

As a child, my parents would joke that my eyes were the color of shit.

I find it hilarious that every blue eyed person I've ever known brags about their eyes and has been complimented about them and yet acts like they aren't proud of them.

Then they literally say you have eyes the color of shit, and act like there's something wrong with you when complain.

>>10247918

I'm an Asuka wannabe, actually. I wear red shirts, rather than carrying a sword.

>Oh I thought you were a man
you changed your mind just cause he said he's an asuka wanabe? you have a lot to learn about weaboos.

>>10248242

Yeah actually. Hypothetically, you could bleach hair with this as well - the melanin synthesis would be turned off anywhere you shot the laser.

The very first paper I cite is about using 585nm LED lamps 2cm away from the samples to inhibit melanin synthesis. As we all know, UV light induces melanin synthesis. We've all seen the tanning response. Basically, by denying the eye/skin/scalp UV exposure, and blasting it with intense (5-20J/cm2) 585nm light, you'd cause a reverse tanning response.

I should confess here - I'm already well into a treatment regimen using 585nm LEDs. Pic related. Repeatedly, the left, treated eye shows up lighter in photos - it's not a shading artifact.

>>10248290

>Oh I thought you were a man

I am. :3

>I saw a baby with super grey eyes today, the mom said they're probably gonna change colour

Yes - everyone is born with blue or gray eyes, which darken with age. Hence why removing the pigment reveals the original lighter color.

>>10248264

Guilty as charged, but I also dislike attention because it so often can turn negative like it is here.

>>10248293

I'm convinced something is happening.

Is it supposed to change the color of your skin because the "after" pictures show also show lighter skin. You are being duped. Or you are shit at photography.

>>10248242

>>10248330

>Is it supposed to change the color of your skin

The cells in the skin around the eye would also experience some level of melanin synthesis inhibition. So yes, you'd expect the skin of the treated eye to be lighter.

>the "after" pictures show also show lighter skin

Actually, the untreated, right eye has a permanent blue-black ring around it from an injury. They're illuminated identically.

>>10248369
>They're illuminated identically.
You clearly don't understand what those words mean.

>>10247531

Chinese guy was lying, the genes necessary to see clearly at night are related to those with color blindness. Look up island population of pinglap.

>>10248388
Motion detection is inhibited by colour detection, it's a ratio. That's why men are far more likely to be colour blind, they have to hunt for prey.

>>10248374

I'm trying to illuminate them evenly. Why would the right eye *always* look lighter than the left eye? Why does the left eye lack the dark dots at the rim that the right eye has? Adjust the brightness - the left eye never reveals dark dots along the rim, and the rim is always lighter than the right eye's rim.

>>10248485
Dude we don't know, you got fucking punched in one eye who the hell cares.

>>10248485
You need a color plate, something you can put in both photos to match the color and brightness balance.

>>10248490

The right, untreated eye that was injured has a darker iris than the LED-treated eye.

>>10248494

The left, treated eye's skin is darker than the right, untreated eye.
