The theme today is glass. Of course, a strict interpreter of the topic would note that my sunglasses aren’t made of glass- but I would argue that a)glass is part of the word, sunglasses, b) the sunglasses are sitting on a glass surface (I think), and c) there is a glass mirror and a glass window reflected in the sunglasses.
I played with the image a bit in Color Efex Pro to make it more striking.

I like your reasoning for the GLASS !!!!
And striking it is! I love this. Nice crisp focus, too and all the reflections (especially the double you (W?) really make the image.. I’d say it meets the challenge perfectly.
