Notes on Meaning

• The primary meaning is functional: eyeglasses with clear lenses for vision correction. The secondary meaning is aesthetic or protective: clear lenses as an accessory.
• It is a compound noun ("kính" + "trắng"), but it functions as a single, fixed term for this specific object. The color "trắng" (white) here means "colorless" or "clear," not literally the color white.
