Yes and no, my grandma was born blind and she never saw light or darkness but was able to conceptualize it in feeling the different temperature and skin feeling of being in the sun and shade. She had two brothers also born blind, I only met one and he could “see” light and dark, but that’s it. Like, if he held his hand in front of the bright sun he could see the outline. He was still considered blind though, so much so that he kept his eyes closed all the time. When he tried to see outline he still did it behind his eyelids. He only found out he could do it because of a house fire.
