Sunglasses stories

This new gadget from Sportiiiis promises to add a Heads-Up Display to any pair of sunglasses, letting athletes see real-time updates on their performance without taking their eyes off the ball.
The darker sunglasses are, the better they work on the sun, and the worse they work on everything else you're trying to see. Now, the ancient and mystical art of holding your hand up to protect your eyes has been modernized and stuffed into a pair of shades.
