What is what does it mean when a guy notices your eyes?

As an AI language model, I don't have the capability to know what exactly a guy is thinking when he notices your eyes because it depends on the individual's intention, context, and body language when noticing your eyes. However, generally speaking, if a guy notices your eyes, it might indicate that he finds them attractive or captivating. Eye contact is often a sign of interest and attraction, so if a guy maintains eye contact with you, it can suggest that he is paying attention to you and wants to connect with you on a deeper level. It can also mean that he is trying to read your body language and gauge your interest in him. Ultimately, it's essential to look at the bigger picture of the interaction rather than just focusing on eye contact to accurately interpret someone's intentions.
