'Sight' in the Bible

And he got up and immediately picked up the pallet and went out in the sight of everyone, so that they were all amazed and were glorifying God, saying, “We have never seen anything like this.”

Regaining his sight he said, "I see people, but they look like trees walking."

Then Jesus placed his hands on the man's eyes again, and he saw clearly. His sight was restored, and he saw everything perfectly, even from a distance.

Jesus called the crowd together with His disciples, and said to them, “If anyone wishes to follow Me [as My disciple], he must deny himself [set aside selfish interests], and take up his cross [expressing a willingness to endure whatever may come] and follow Me [believing in Me, conforming to My example in living and, if need be, suffering or perhaps dying because of faith in Me].

And Jesus answered and said unto him, What wilt thou that I should do unto thee? The blind man said unto him, Lord, that I might receive my sight.

And Jesus said unto him, Go thy way; thy faith hath made thee whole. And immediately he received his sight, and followed Jesus in the way.
