also: めのよい
expression, i-adjective (yoi/ii class)
having good eyesight
Describes a person or animal with sharp vision; often used attributively as in 目のいい人.
彼はとても目のいい人で、遠くの看板も読める。
He has very good eyesight and can read signs far away.
目のいい鳥は、空から小さな獲物を見つける。
Birds with good eyesight spot small prey from the sky.
Similar meaning but uses the particle が, making it a full clause rather than a prenominal phrase. 目のいい directly modifies a noun, while 目がいい can stand as a predicate.
Phrase composed of 目 (eye) + の (attributive particle) + いい/よい (good). The structure is a common pattern for describing inherent qualities.
