prevents fogging
Etymology
'anti-fog' is a compound formed from the Greek prefix 'anti-' (from Greek 'anti' meaning 'against') and the English noun 'fog' (from Middle English 'fogge' meaning 'mist' or 'thick vapor').
'anti-' entered English usage via Late Latin and formed many compound words; 'fog' developed from Middle English 'fogge' (with possible Norse/Germanic influence) into modern English 'fog'. The compound 'anti-fog' arose in modern English (20th century) as a technical/consumer term for treatments that prevent fogging.
Literally meaning 'against fog', the compound came to be used specifically for coatings, agents, and products that prevent condensation on surfaces; the literal sense remains but usage has specialized.
