These special glasses were part of a contest before the Great War; if a visitor to Nuka-World was able to use these glasses to reveal ten hidden images of the park's mascot Cappy around the park, they would win a visit into the office of John-Caleb Bradberton, the inventor of Nuka-Cola.
The classes are similar to the fashionable glasses, but are red and have bottle cap shaped lenses. They provide no resistances of any kind, but they are more useful in spotting the hidden Cappy images scattered throughout the park as part of Cappy in a Haystack.
