I say why no eyeglass designed for one that never looks older? (7)
I believe the answer is:
ageless
'i say why no eyeglass designed for one that never looks older?' is the definition.
Both the definition and answer are adjectives. Perhaps they are linked in a way I don't understand?
This is all the clue.
Can you help me to learn more?
(Other definitions for ageless that I've seen before include "Lasting a long time" , "not appearing to get old" , "not getting on" , "Staying young" , "Ever young" .)
