I think it's common for people who develop this condition at an early age to assume that everyone perceives the world in the same way as they have no objective reference frame - a bit like those stories of people who grow up thinking bananas are spicy when in fact they're mildly allergic to them. It may be that you have a mild version of VSS, or maybe your vision is atypical in some other way? The comparison with tinnitus is appropriate in the case of VSS, as I understand that it's theorised to be the visual equivalent.
