These junior eyeglasses are made of eco-polyamide, a naturally derived plastic that Polaroid has chosen to promote sustainability. Ideal for 7 to 10-year-old kids, flexible hinges provide extra comfort, while magnetic clip-on shades snap easily onto the front frame to turn them into sunglasses. There is no shortage of details to define the style of these glasses, including the front, logo and end tips in the same contrasting hue.
