ProDesign Denmark is at it again, mixing clean and minimalistic lines with vintage industrial accents for a hint of the Golden Age in the modern day. A contemporary design with Danish architecture and furniture influences sets the tone for the new Danish Heritage Collection. Sleek blacks, deep blues and warm browns make these frames wearable for everyday life, while classic tortoise patterns give them a hint of urban edge. What’s more is each optical frame effortlessly transforms into a pair of must-have sunnies with a simple click of a clip-on lens. These specs-turned-shades instantaneously have a trendy double bridge and added metal accents for extra panache. Check ‘em out, below.
