New Defender's Study Bible Notes
8:24 men as trees. When a blind person is suddenly enabled to see by means of eye surgery, he at first has no proper depth perception, finding it difficult to put what he sees in proper perspective. This first stage of Jesus’ miracle would roughly correlate with the first perceptions by a newly healed blind person. The second miracle, however, gave the man instantaneous normal sight, thus clearly showing that this was not a naturalistic process.
