Although I may have eyes, I cannot see. I have a round brown face with lots of acne. What am I?

Why this works

This riddle plays on the double meaning of the word "eyes." In the context of a potato, "eyes" refer to the small buds or growth points on its surface, which can look like tiny spots. The description of having a "round brown face" fits the typical appearance of a potato, while "lots of acne" humorously refers to these eyes, making it a clever way to describe the vegetable without directly naming it!
