Just like the Hemsworth brothers, no one could blame you for confusing these spectacles with their sibling. They look the same and do the same job. It\'s just that one of them is slightly bigger. The 7224 has a slightly larger lens for a wider eye and longer arms for a more relaxed fit. Choosing between the 7222s and 7224s, is a bit like choosing between Chris and Liam – you\'re going to be happy either way. They\'re both good looking and will perform well; it\'s just personal preference. And, ultimately, no one\'s going to know which one you went for anyhow.
