noun. a person who is or people considered highly attractive to look at, often implying that they are but lacking in intelligence or depth. something intended to be attractive to the eye without being demanding or contributing anything essential.

Saying that a person is "just eye candy" means that their physical appearance is all that matters, and that their intelligence or education is not important. "Just eye candy" is never a compliment, and it almost always is an insult. It means you are aesthetically pleasing, you look good.

Eye candy is used to refer to people or things that are attractive to look at but are not interesting in other ways. Forget the acting, just look at the eye candy. Animation has stopped being eye-candy for kids and become mainstream entertainment.
