The word for sunglasses in Spanish is gafas de sol.
In Spanish, gafas refers to glasses, while de sol means ‘of the sun.’ Therefore, the term directly translates to ‘glasses for the sun.’ You can also hear the term anteojos de sol in some regions, which is another way to refer to sunglasses, particularly in Latin America.
When using the term in a sentence, you might say: Voy a comprar unas gafas de sol. This means, ‘I am going to buy some sunglasses.’
