The rules only list four special senses:How did you arrive at this conclusion?
Blindsight: within it's range, you can see something that has the Invisible condition without relying on physical sight
Truesight: You see creatures and objects that have the Invisible condition.
Tremorsense: can technically let you know where a creature under the Invisible condition is located
Darkvision: lets you see in Darkness as if it were Dim Light.
Nowhere, and I mean NOWHERE, in the DMG or PHB does it define what physical/normal sight is--nor is it listed as a special sense--so that means it follows the natural language definition
Rules do what they say they do, and two outright state they can break it, and one can "bypass" it.
Hide tells you to make a stealth check and use the result as the DC for a creature to FIND you with a Perception check, which the PHB defines as "Using a combination of senses, notice something that’s easy to miss." The Invisibility spell has no such requirement, and since the rules do not list physical sight as a special sense, then it can't be used to break the Invisibility spell.
