Plural of Spectacles
In the eyewear sense, “spectacles” is a plural-form expression and normally takes plural agreement. Count one set as “a pair of spectacles” and more than one as “pairs of spectacles.” This is distinct from singular “spectacle” meaning an unusual or impressive display/event.
For eyeglasses, “spectacles” is plural in form. One item is normally “a pair of spectacles.”
