There are two songs that use those lyrics:
1. "Everything is Beautiful" by Ray Stevens
There is none so blind as he who will not see.
We must not close our minds; we must let our thoughts be free.

2. "None So Blind" by Z. Mulls
There are none so blind as those who will not see
None so blind as you and me
