People blow on it to clear the lens of spectacles.

As a result, the water vapours present in the air surrounding the glass condense and get attached to the glass surface. Consequently, the glass becomes wet.

Hence the glass can be wiped properly due to presence of water droplets. so , people blow air into their spectacles before cleaning them.
