Do you know what was the most frequently performed healing of Jesus? Curing blindness. There are at least 5 specific episodes in which Jesus resolved someone’s physical blindness (Matthew 9:27-31; 12:22; Mark 10:46-52; Luke 8:22-26; John 9:1-7) as well as references to Jesus healing numerous others who were blind (Matthew 15:30; Luke 7:21). Maybe the reason Jesus so frequently remedied physical blindness was to expose our need for better spiritual vision.
18 as we look not to the things that are seen but to the things that are unseen. For the things that are seen are transient, but the things that are unseen are eternal.”
2 Cor. 4:18
