What this suffix does
-eyed forms compound adjectives with two main groups. The first describes physical eye appearance (blue-eyed, dark-eyed, bright-eyed). The second — and more literary — describes a way of perceiving the world or a state of the mind visible in the eyes: wide-eyed (full of wonder or surprise), eagle-eyed (sharp perception), starry-eyed (idealistic and naive), bleary-eyed (tired). These figurative compounds are especially common in fiction and in describing both vision and perspective.
