Acts 9:8

And Saul arose from the earth; and when his eyes were opened, he saw nothing; and they led him by the hand, and brought him into Damascus. And he was three days without sight, and did neither eat nor drink.

That Saul was temporarily blind following the appearance of Christ to him is clear from the fact of their leading him. What a different status came to him as a result of his blindness; and how utterly unlike his projected entry into Damascus was the entry itself. Not as a savage persecutor, but as a helpless blind man, he entered the city where his life would be changed forever. The emotional shock he received is indicated by his not eating anything for three days.
