Costa Vision
Results from the ultra-violet rays imparting a darker tone on skin while wearing a pair of Costa Del Mar sunglasses. This leaves a distinctive Costa Del Mar sunglass imprint on face where ultra-violet rays could not penetrate the frame and lens.
Coming back from your Caribbean sailing exhibition, you take off your Costa Del Mar, 580 Brine, sunglasses. A sorostitute mentions you have the best Costa Vision she's ever seen, she then later becomes your future slam piece.
