It would be a very subtle tweak to your blue perception. UV sensitivity is quite low even without the lens filtering it out.

As cool as accidental historical biohacking is, I think the Monet-UV hypothesis should be taken with a grain of salt.

The argument in favor of it is that Monet was an exceptional trained painter, and one specialized in colors on top of that. He might have been extra sensitive to colors compared to most humans (both in the sense of biological sensory sensitivity, as well as trained ability to perceive colors).

It is possible, if somewhat unlikely, for men to also be tetrachromats.

Color vision is encoded on the X-chromosome, right? And human tetrachromatocy depends on having two X-chromosomes with different color vision genes[0]. So wouldn't a hypothetical tetrachromatic male need to be an XX-chromosome male[1], and on top of that have one of the X-chromosomes carrying the deutanomaly, protanomaly or tritanomaly mutation, and on top of that have this mixture manifest itself as having four color receptors instead of three? Or is there another theoretical way that I'm missing?

If my educated guess is correct then "somewhat unlikely" seems like quite an understatement to me! :D

(I have protanomaly myself, and never considered that men could hypothetically be tetrachormats as well. This was a fun through exercise)

Myself, I've had ICL surgery (Implantable Collamer Lens) as vision correction in both eyes (I wasn't a good candidate for Lasik). With it includes 100% UVA/UVB blocking. It's basically a permanent contact lens implanted behind the iris and in front of the the natural lens. So, sadly, no ultrahuman UV vision for me. My only "bionic" ability is saving my natural lens and retina from UV exposure.

I bet your eyes do a cool robotic ‘shine’ when viewed in some lights (eg. in a dark room with a diffuse light behind the viewer) though.

I dobt know if other people can see it looking at my eyes, but on certain low light conditions, I do see a subtle elongated 'X' sorta looks like a mostly transparent '>---<' at the bottom of my vision. From talking with my Doc, its a small side effect of how they fold the lense implant when they insert it to minimize the size of the incision in the cornea. I dont normally notice it, and since its on the peripheral, it is pretty easy to ignore.

Edit: spelling
