Yeah weirdly (or maybe not) when we get down to it too, every sense is a sense of touch. Your ears touch the vibrations in the air, your nose touches the particles in the air, your eyes feel the touch of the light that hits them, skin is self explanatory, and then your tongue, which is touching on a very miniscule level while checking for all the chemicals and seeing if your nose is confirming that the touch is similar to the particles
Though isn’t it a stream of photons that hit the photoreceptors? So not touch in the mechanical sense, but things are still “touching” in the colliquial sense, like a very minute and specialized version of smell

Disagree on eyes. Light is EM radiation, not a mechanical wave like sound. Your retina isn’t ‘touching’ anything but the vitreous.
