eyesights
Powers of seeing
Eyesights is a rare plural of eyesight, the faculty of vision.
Since eyesight is typically an uncountable noun referring to the general ability to see, the plural form appears mainly in specialized or poetic contexts where distinct instances or types of vision are being compared: The eyesights of predatory birds far exceed our own.
In everyday usage, the singular eyesight serves for both individual and collective reference.
