What does the Bible say about opening blind eyes?

Isaiah 42:6-7 prophesies about the mission of the Lord Jesus, declaring that He was sent to open blind eyes and bring captives out of darkness. This opening of the eyes is primarily spiritual, pointing to the divine action of God in granting understanding and faith to those who are spiritually blind. The fulfillment of this prophecy is evident in the New Testament, particularly in the miracle of healing the man born blind in John 9, showcasing that Jesus has indeed come to provide both physical sight and, more importantly, spiritual enlightenment to the lost.
