Hunayn ibn Ishaq's Book of the Ten Treatises of the Eye is a 9th-century theory of vision based upon the cosmological natures of pathways from the brain to the object being perceived.
 This ophthalmic composition is heavily derived from Galen's "De placitis Hippocratis at Platonis" and "De usu partium", both in terms of the anatomy and physiology being described.
 Hunayn's triumph comes from the systematic presentation of the parts of eye and the subsequent additions he made to the cosmological aspects of the work.
 Its early translation to Latin also provided a means for medieval ophthalmologists in the West to come into contact with the work of Galen.
