Fashionistas who are required to wear glasses will love this color-changing eyewear from Portuguese industrial designer, Luis Porem.

Created as an entry for the Opus Award, the RbG Rainbow Glasses are hollow and allow the wearer to fill them with various colors of ink to match their outfit.

The RbG glasses are made from clear plastic with an internal channel for the colored ink hto pass through and a flexible, enclosed hinge to prevent leakage. This “paints” the frames with the desired color and allows you to choose the right hue for whatever occasion presents itself.
