What If We Could See All Wavelengths Of Light?

Light is a form of electromagnetic radiation that consists of components with different wavelengths. You might already know that visible light, i.e. the light that we actually see and perceive, is just a small portion of all the light there is. So, what if we could see all the other components of the spectrum as well?

Let’s start with the left extreme of the spectrum…

Radio waves

From your smartphone and television to computer networks and artificial satellites orbiting the planet, everything relies on radio waves to operate. Apart from these modern conveniences, almost everything in the universe emits radio waves, so being able to see these waves does more harm than good to your eyes, and it’s even worse for your brain! The latter would be bombarded with so much information in countless colors at all times that you would not be able to register/isolate anything at all, making you feel blinded by the influx of so much light and color.

The background lighting that fills the universe is actually the afterglow from the Big Bang. With microwave vision, we would see light shooting at us from everywhere in the sky (however, a small amount of that would be blocked by our atmosphere).

Other things in daily life that possess microwaves (like microwave ovens, GPS, traffic surveillance systems etc.) would also appear very brightly lit.


With infrared vision, colors would essentially disappear, and you would only see things through different tones of heat. The hotter the object, the brighter it would appear. Human beings emit heat too (heat signature), so you would see every other person lit up according to how hot he/she is (no pun intended).

To add to that, you would be able to see people through other objects, such as clothes, walls etc., but they would appear less like their usual selves and more frightening instead, depending on their heat signature.


Normally, humans cannot perceive ultraviolet thanks to the presence of cones that only detect red, green and blue in their eyes. However, certain animals like reindeer, sockeye salmon and butterflies do have additional cones that enable them to perceive UV light.

That being said, humans can perceive UV light, but it comes at the cost of their eye lenses. People who have aphakia (the absence of an eye lens due to injury, surgery, ulcer etc.) have reported being able to see UV wavelengths. Claude Monet, an eminent painter and a “father” of French Impressionist painting, was able to see “impossible” colors due to the removal of lens following a cataract surgery.

Electronic gadgets that emit UV light (e.g., computer screens, tanning beds and UV lamps) would appear brighter, and seeing things with the UV filter would give our current perception of colors an overhaul.

Thanks to movies and pop culture’s love for X-ray vision, we have been led to believe that X-ray vision will let us see through other people’s clothes – as well as buildings and underground bunkers. The truth is, even if you could see through someone’s clothes using your X-ray vision (which, by the way, you can), it’s only their bones that you would be able to see. X-rays have a very small wavelength and high amounts of energy, which is why they can penetrate a lot of stuff to give that ‘see-through’ vision effect.

Having X-ray vision would be far less cool than pop culture has led you to believe: you’d see a slightly different-colored sky (the atmosphere has small amounts of X-rays) and you would need an iron eye mask to catch any shut-eye. X-rays can pass through thick layers of fat and muscle, so what opposition could thin eyelids possibly offer!

Gamma rays

Sitting at the top of the electromagnetic spectrum (in terms of frequency) are gamma rays, which consist of high-energy particles that can penetrate almost everything around us. Since there aren’t many sources of gamma rays around us, there wouldn’t be much difference in your vision. However, you could see radioactive materials (that emit gamma rays), but you should probably keep your distance from them. You wouldn’t want to see too many gamma rays, or else you might end up like Dr. Bruce Banner.

Gamma ray exposure

If comic strips are to be believed, gamma rays not only transform you into a raging monster, but they also change your name.

To conclude, it’s fair to say that having any other type of vision besides the one we have now would make things more problematic or uncomfortable for us. However, if there was an option to toggle these special visions on and off, I think it would be pretty darn cool.
