Just as one would see if they were visually impaired. Of course, this is a reference to the Duo monsters coming up and not meant to be an insult to visually impaired. The card's info says:
Once per turn, you can activate 1 of these effects: - Treat 1 face up Duo monster as an Effect Monster. - Special Summon 1 Duo monster from your hand.
