'bespectacled' originates from English, formed from the prefix 'be-' plus 'spectacled', where 'be-' is an intensifying or causative prefix and 'spectacled' relates to 'spectacle' (from Latin 'spectaculum').

'spectacle' comes from Latin 'spectāculum' (from 'spectare' meaning 'to look'), passed into Old French and Middle English as 'spectacle'; 'spectacled' is the adjectival form meaning 'having spectacles', and 'bespectacled' arose in Modern English by prefixing 'be-' to that adjective.

Initially related to 'spectacle' (an object for viewing or a sight) and the act of looking; over time the compound adjective came to mean specifically 'wearing spectacles (glasses)'.
