Thirty second IQ test

It’s a single question IQ test – and is basically a pass or fail. I failed.
There’s a mute who wants to buy a toothbrush. By imitating the action of brushing his teeth, he successfully expresses himself to the shopkeeper and the purchase is done.
Now, if there’s a blind man who wishes to buy a pair of sunglasses, how should he express himself?

Think about it before looking down for the answer…
He opens his mouth and says, “I would like to buy a pair of sunglasses, please”.
Be very honest with yourself. How did you do?
