It is often useful to calculate the front and back vertex powersor focal lengths. For lenses with powers P1= diopters and P2= diopters with separation d = cm, Calculating the path rays of light take through the eye and how an image is created is very complicated because the eye's lens consists of different layers that refract light to different degrees. Moreover, the lens also changes shape. However, Allvar Gullstrand succeeded in doing just that in the 1890s using advanced mathematics.

He subtracted 0.8 mm to allow for the coats of the thicknesses of the eyes to get an internal axial length of 23.1 mm. Figure 9 shows a schematic diagram of his eye, with the Gullstrand–Emsley model eye shown for comparison.

Allvar Gullstrand, (born June 5, 1862, Landskrona, Sweden—died July 28, 1930, Stockholm), Swedish ophthalmologist, recipient of the 1911 Nobel Prize for Physiology or Medicine for his research on the eye as a light-refracting apparatus. Gullstrand studied in Uppsala, Vienna, and Stockholm, earning a doctorate in 1890.

A model for the human eye is proposed, similar to Gullstrand’s well-known 4-radius model, however with the front surface of the cornea and the back surface of the crystalline lens taken to be rotationally symmetric aspherics. Whereas for the cornea a polynomial is used based on experimental data of Bonnet, a second-order parabola was tentatively adopted for the back surface of the lens. A model of the human eye is presented with the crystalline lens treated as having a gradient-index structure. By defining an accommodation index I ranging from 0 (unaccommodated) to 1 (accommodated), the optical parameters of the eye in various states of accommodation may be found. The results are in agreement with experimental values. Gullstrand eye model divides the refractive power of the eye into three main components: anterior cornea (point A), posterior cornea (point B), and lens (point C). TABLE 1.
