The speaker is wrapped up in someone's eyes, and says they communicate more than words ever could. Early on, the poem makes big claims: the eyes can "beat all words" and "replace all stars." Then it takes a gentler turn. The person can't give their eyes away, because they need them to see, and that includes seeing how beautiful those eyes are.
The second half is more vulnerable. The speaker admits that when they look, they see nothing, not the pain, the love or the journey, because the two people "don't meet eye to eye." The line works both literally and as a hint that something stands between them. Instead of giving up, the speaker decides to listen. If sight fails, hearing will grow stronger, and they will tune in to whatever the eyes might say.
The mood is tender and longing, with a quiet ache underneath. It feels like admiration mixed with the wish to be truly seen and understood in return.
