'eye-related' originates from the combination of 'eye' and 'related', where 'eye' refers to the organ of sight and 'related' means connected or associated with.

'Eye' comes from Old English 'ēage', and 'related' comes from Latin 'relatus', the past participle of 'referre', meaning 'to bring back'.

Initially, 'eye-related' simply meant anything connected to the eye, and this meaning has remained consistent.
