Will we ever be able to see the multitude of colors and stuff

Maybe if we could design retinal pigments that react to different frequencies than our own do, and then implant them into stem cells and let them grow in there.

this means that you would have to design enzymes that anabolize those new pigments and then introduce genes for those new enzymes into that stem cell, too. we are talking about up to hundred genes plus all their regulators sequences introduced in a way that does not switch off any important original shit
seems more or less impossible to me because designing those new synthethizer genes alone could take hundred years or so.

*forgot:
and it would be much easier to simply modify the already existing pigments with highly selective drugs, bound to aptamers or something

Not realistically any time soon. I mean you could say that anything is possible in a long enough timeline

Other animals can see IR and UV, who knows how they perceive it:

"The ability to sense infrared thermal radiation evolved independently in several different families of snakes. Essentially, it allows these animals to "see"[1] radiant heat at wavelengths between 5 and 30 μm to a degree of accuracy such that a blind rattlesnake can target vulnerable body parts of the prey at which it strikes.[2]"

Nectar guides are markings or patterns seen in flowers of some angiosperm species, that guide pollinators to their rewards. Rewards commonly take the form of nectar, pollen, or both, but various plants produce oil,[1] resins,[2] scents,[3] or waxes... in some plants, such as sunflowers, they are visible only when viewed in ultraviolet light. Under ultraviolet, the flowers have a darker center, where the nectaries are located, and often specific patterns upon the petals as well. This is believed to make the flowers more attractive to pollinators such as honey bees and other insects that can see ultraviolet.

It's like that philosophical idea of qualia, who knows if the red that I see is the red that you see? What if what I see as red you see as orange, what you see as red you see as violet? Like the spectrum is shifted over.

There's nothing special about colors. It's just a sensory mechanism to help our depth perception and object recognition that utilizes the differences in frequencies of light that are absorbed or reflected between different materials

The pigments in retinas provide an image with contrast. It's neural networks that decode and construct visualized models which are then perceived. If we wanted to alter our perception, we would tinker with these networks rather than the retina.

I think you're confusing colors and frequencies

With a diet that regulates vitamin A and gives you a variation of it you can see a little bit into IR.

With a trivial operation you can see UV but that is not recommended since the retina is damaged by it over time.

if only there would be some kind of device
a sort of electronical mcguffin that could register, amplify and visualize the stuff you're not seeing

man can only hope that one day such magnificent device will become reality

Thing is that we don't have to start from scratch since human tetrachromats(four cones) already exists due to nature being wonky. See article.

why even live?

>Humans cannot see ultraviolet light directly because the lens of the eye blocks most light in the wavelength range of 300–400 nm; shorter wavelengths are blocked by the cornea.[24]

Even if you had the cones to detect it, you still wouldn't see ultraviolet light.

The point is that we do know something about the people with four cones and the genes that cause it. It will be easier in the future maybe inmplant it into other people if they want it. And as other anon mention you can see UV with a operation, it is dangerous for now but it may change.

>The average person has three cones, which enables him to see about one million colors. But Antico has four cones, so her eyes are capable of picking up dimensions and nuances of color—an estimated 100 million of them—that the average person cannot.

Regardless of UV seeing 100 times more colors with one extra cone, around 100 million of them, is still pretty neat imo

IR would be useful but it'd get annoying. UV is just a nice way to make going outside painful
