Human being species viewing the infrared spectrum.

We can see in the spectrum for a variety of reasons, including limitations due to our eye anatomy, photoreceptor sensitivity, and evolutionary adaptation. The human eye is specifically adapted to detect visible light. It consists of structures like the cornea, lens, and retina that are sensitive to the wavelengths of light within the visible spectrum. Infrared light does not activate the photoreceptor cells in the human retina responsible for vision. Furthermore, the two main types of photoreceptor cells in the human retina are rods and cones. Cones are responsible for color vision and are sensitive to different wavelengths within the visible spectrum. They are not sensitive to infrared wavelengths. Rods, which are responsible for low-light vision, are also not sensitive to infrared light. Finally, human vision has evolved to be most sensitive to the wavelengths of light that provide the most useful information for our survival and well-being. Visible light allows us to perceive the colors of objects, detect changes in our environment, and recognize important visual cues, like the redness of ripe fruit or the blueness of clear skies.

Can this be achieved by Brain surgery?

Maybe? 🤔🤔

But why go to that extreme? While we can't naturally see in the infrared part of the spectrum, technological advancements have allowed us to develop infrared imaging devices and cameras that can capture and display infrared images (for example, night vision goggles, thermal imaging, medical imaging, etc.) they all allow us to visualize the heat emitted by objects and organisms and detect differences in temperature.

Thanks.

Unless you're okay with turning into a cyborg, then no it is not possible.
