Why These Endings Work

All feminine (die) nouns stay completely unchanged in the singular across Nominative, Accusative, Dative, and Genitive.

Feminine nouns never change their own ending in the singular across all four cases.
Plural "Brillen" already ends in -n or -s, so Dative plural stays Brillen.

Pattern summary: Only the article changes in singular (die / die / der / der); plural takes -n in Dative unless ending in -n or -s.
