Relating to or characterized by the condition of blindness or loss of sight.
From ablepsy or ablepsia + the suffix '-ical' (relating to). This adjective form developed in English medical literature during the 17th-18th centuries to describe conditions or qualities associated with blindness.
Adding '-ical' to make adjectives was huge in medical terminology—it let doctors turn nouns into descriptive words, so 'ableptical symptoms' meant symptoms of blindness. It's the same pattern we see in 'magical,' 'tactical,' and 'comical' today!
