The Em-sley eye is the simplest model, as it considers the entire eye. The pupil is the black "window" of the eye. After graduating from the gymnasium, Helmholtz in 1838 entered the Friedrich Wilhelm Medical Institute in Berlin, where he received a free medical education on the condition that he serve eight years as an army doctor.

Although Helmholtz had relatively crude instruments and was unaware of much of what occurred behind the iris with the ciliary muscles and zonules, and despite significant evidence today that contradicts his mode of action for accommodation and presbyopia, the Helmholtz theory is still the dominant theory prevailing today throughout ophthalmology. Relaxation Theory of Helmholtz eye is at rest and focused for distance ciliary muscle is relaxed eye makes an effort to focus on a near object ciliary muscle contracts bulk of the anterior ciliary body moves forward release in tension on the zonular fibres elastic capsule moulds the lens into a spherical form 5.
