NB The word глазок also means "peephole"; as a diminutive meaning "small eye" (used mostly in the Plural form глазки), it is affectionate when applied to a child, but somewhat pejorative when applied to an adult, especially to a man.

NB The word глазёнки, often said of a child's eyes, is the ordinary diminutive, being somewhat endearing and conveying the usual implication of small size. The word глазоньки, on the other hand, does not imply small size and is especially endearing and affectionate.
