Why does Jesus touched the blind man's eyes TWICE @ Bethsaida?

Mark 8:22-25 --> Why does Jesus touched the blind man's eyes TWICE at Bethsaida?

22 They came to Bethsaida, and some people brought a blind man and begged Jesus to touch him. 23 He took the blind man by the hand and led him outside the village. When he had spit on the man's eyes and put his hands on him, Jesus asked, "Do you see anything?" 24 He looked up and said, "I see people; they look like trees walking around." 25 Once more Jesus put his hands on the man's eyes. Then his eyes were opened, his sight was restored, and he saw everything clearly. 26 Jesus sent him home, saying, "Don't go into the village. " 

My tots over this passage -->
1st time Jesus had spit on the man's eyes and put His hands upon him, the man was able to see but it was a blurry image - seeing people that look like trees.. That tickles me, coz my imagination went a little wilder.. But how does he know people and trees look like?
2nd time Jesus put His hands on the man's eyes again, and the man's sight was restored.

What I can derive from here is that because eyes are related to seeing, and seeing is related to revelation. Having his eyes opened, he is able to see the Word of God is alive (Jesus is the Word of God). Next, Jesus asked him if he's seeing anything? Somehow, something must have gone on within him that he started to believe, though he saw the people look like trees in the very first instance. It was somewhat like a 60-fold healing when he spoke forth, believing in his heart, and he's also receiving a revelation. THEN Jesus put His hand on the man's eyes again and the man looked [INTENTLY - as stated in AMP bible] before he was restored and saw everything distinctly.

I believe that the man had his eyes so fixated onto Jesus first - seeing Him as the Messiah and his heart changed toward Jesus Himself. That was when he was fully restored with perfect vision!
So, when we fix our eyes on Jesus Himself, we can see that all our problems will be fixed, and restoration will come and finally ABLE TO SEE THE GOODNESS OF GOD's HEART AND DIRECTION IN OUR LIVES.
