What is the Swiss term for holes or eyes in cheese?

There isn't a specific Swiss term for the holes or eyes in cheese. The term "eyes" ("œils" in French) is commonly used in Switzerland, as it is in many other cheese-producing countries.

However, if you're talking about the holes created during the cheesemaking process, you might also hear them referred to as "holes" ("trous" in French) or "bubbles" ("bulles" in French).

It's worth noting that the Swiss are particularly known for their "Emmental" cheese, which is famous for its large, evenly spaced eyes.
