Gafas vs. lentes vs. anteojos
The Spanish words gafas, lentes, and anteojos all translate to glasses or eyeglasses. While they are often interchangeable and understood in most Spanish-speaking regions, their usage varies significantly depending on the country and context.
Gafas
A1This is the most common and universal term for glasses in Spain. It is considered the standard, neutral word and is widely understood everywhere. It can refer to both prescription eyeglasses and sunglasses (gafas de sol).

(I need new glasses to be able to read the newspaper.)

(My glasses broke while I was playing basketball.)
¿Has visto mis gafas de sol por alguna parte?
(Have you seen my sunglasses anywhere?)

(Since I started wearing glasses, my headache has disappeared.)
Lentes
A2This word is the preferred term in many parts of Latin America, especially in Mexico, Colombia, and Central America. The word lentes literally means lenses, and it can refer either to the complete pair of eyeglasses or just the glass parts. It is also the primary word for contact lenses (lentes de contacto).

(I'm going to the optician to buy a new pair of glasses.)

(My grandmother needs glasses for seeing up close.)
Anteojos
A2This word is also widely used in Latin America, particularly in the Southern Cone countries like Argentina, Chile, Uruguay, and Paraguay. The word is a direct combination of ante (before) and ojos (eyes). In some regions, it can sound slightly more formal or old-fashioned than lentes, but it is still a very common and standard term.

(Without my glasses, I can't make out the letters on the screen.)

Summary
In summary, the choice between gafas, lentes, and anteojos is mainly geographical. Use gafas in Spain. In Latin America, both lentes and anteojos are common, with lentes being frequent in Mexico and Central America, and anteojos in the Southern Cone. Lentes uniquely can also refer to just the lenses or contact lenses. Despite these regional preferences, all three words are generally understood by most Spanish speakers.
