Swiss cheese is a generic name in North America for several related varieties of cheese.
It is mainly of North American manufacture, and resembles Emmental cheese, a yellow, medium-hard cheese that originated in the area around Emmental, in Switzerland.
Some types of Swiss cheese have a distinctive appearance, as the blocks of the cheese are riddled with holes known as “eyes”. Swiss cheese without eyes is known as “blind”. (source)
