Arabian scientists made progress in the art of healing, especially in the use of curative drugs. They established hospitals and even provided advanced medical care to prisoners. They made careful studies of diseases and did creative work in the optics, or eye care. Possibly the greatest contribution of Islamic Civilization to the medical world of the Middle Ages was in the writing of medical text books.
