Is there anyways to make glasses or something that can make humans see more colors?

Sort of. Your eyes are weakly sensitive to infrared light. It normally gets swamped out by the other colors of light, but you can make [goggles that](https://eskimo.com/~billb/amateur/irgoggl.html) block out the visible spectrum but not infrared, allowing you to see it.
It’s not really a color, but [yellow filter glasses](https://pubmed.ncbi.nlm.nih.gov/1586884/) improve your ability to detect contrast.
The colors that you see, and how your brain experiences those colors, is related to the ratios of 3 different color sensors (plus a brightness sensor that does not perceive color) in your eyes. Each portion of your vision system can only perceive so much or little light so you cannot *experience* seeing a totally different color the ones you can see naturally.
However you could make glasses or a combination of camera plus screen that “translates” invisible wavelengths to visible ones. You can buy one today. They are called thermal cameras or FLIR and are readily available. What
Basically, no. This is primarily because colour is the brain’s interpretation of certain wavelengths of light, not a feature of the eyes themselves. Colour is purely a subjective experience. This is what leads to the theory that no two people see the “same red”, which I quite like.
You can create glasses that see in infra-red or ultraviolet light, but they work by transalting that wavelength in to a weavelength our eyes can discern.
Wouldn’t infrared glasses be that? They allow you to see the infrared colors. There aren’t X-ray glasses but the digital X-ray sensors showing on a screen essentially allow you to see X-ray colors also.
There are devices that convert other forms of light into visible light, but humans have hardware and software limitations that prevent us from actually seeing beyond the visible spectrum. I would be curious if some kind of mutation exists that allows people to see infrared or something. Mutations exist that limit what wavelengths people can distinguish after all.
