Unlimited lenses ordered and worn by daughter (7)
I believe the answer is:
endless
'unlimited' is the definition.
(thesaurus)
'lenses ordered and worn by daughter' is the wordplay.
'ordered' indicates anagramming the letters.
'and worn by' means one lot of letters goes inside another.
'daughter' becomes 'd' (genealogical abbreviation).
'lenses' with letters rearranged gives 'enless'.
'enless' placed around 'd' is 'ENDLESS'.
(Other definitions for endless that I've seen before include "Occurring so frequently so as to seem uninterrupted" , "Going on forever, lacking conclusion" , "without finishing" , "Tiresomely long" , "'Eternal, perpetual (7)'" .)
