The law assures that the eye focuses on far away targets with an upright head and adapts to a special angle for each glaze that occurs; even though there are numerous ways eyes could position.

Other contributions to the field of ophthalmology include: the translation of German textbooks to Dutch, the clinical application within the field, acknowledgment of glaucoma and its subtypes, analysis of brain function, and the reduced eye model. Donders is also well recognized in the dental community for naming the "space of Donders", the space between the dorsum of the tongue and the hard palate when the mandible is at rest.
