I can See Clearly Now

Well it is not the starting line of the song, I am refering to my new glasses I got. Man it is a different world, I feel motivated as I can see things the way they used to appear few years ago... For few years now even with glasses I wasnt able to see the same, but I always felt the glasses wouldn't help me either, boy I was wrong. For example the lady at the counter looked a different person with new glasses, I was so happy that I decided to take a small walk in the mall to exercise my new found Vision. If I could appreciate this how would a Blind person with no vision gets his vision back?
