St Lucy was a young Christian Roman maiden who was promised in marriage to a pagan man. When he found out she was a Christian, he denounced her to the emperor and she was sentenced to death. Her eyes were torn out as part of her martyrdom, making her the patron saint of those with vision problems.
Below is a lovely prayer to St Lucy.
St Lucy, you preferred to let your eyes be torn out instead of denying the faith and defiling your soul; and God, through an extraordinary miracle, replaced them with another pair of sound and perfect eyes to reward your virtue and faith, appointing you as the protector against eye diseases. I come to you for you to protect my eyesight and to heal the illness in my eyes.
O St Lucy, preserve the light of my eyes so that I may see the beauties of creation, the glow of the sun, the color of the flowers and the smile of children.
