Answer-Frame front
Part of the frame that extends to the ear & holds the spectacles in place ✔Correct Answer-
Temples
Category of temples that bend down behind the ear & follow the contour of the skull, resting
evenly against it ✔Correct Answer-Skull temples
Category of temples which are generally straight & hold the glasses on primarily by pressure
against the side of the head ✔Correct Answer-Library temples
Category of temples that can be used either as skull or library temples depending on the
manner in which they are bent ✔Correct Answer-Convertible temples
Category of temples which curve around the ear & extend to the level of the ear lobe; often
used in children's frames & safety eyewear ✔Correct Answer-Riding-bow temples
Category of temples which are similar to riding-bow but are constructed from a metal flexible
coiled cable ✔Correct Answer-Comfort cable temples
The measuring system that draws an imaginary line through the middle of the eyewire both in
the horizontal & vertical planes when measuring eye size; can be inconsistent with unusual lens
shapes ✔Correct Answer-Datum system
