41-45. https://hrcak.srce.hr/102780. The pressure at the back of the eye produced an entoptic ring phosphene, which he kept in the centre of the visual field. 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. ** This optical description incorporates the parameters of Gullstrand’s Schematic Eye (1908). Upon elimination of the collimator lens, the field lens, the continuous gradient index of refraction for the lens, and limiting the field angle to ~1.0; the resulting simplified paraxial (Gaussian) optics is identical to that of Gullstrand.

In our example, the eye with axial myopia would have an axial length of greater than 24.00 mm (Figure 2). Refractive myopia is the condition when the eye has too much convergent refractive ability for its ideal length. The extra convergence of the light is The refractive index for air is taken to be 1.000, and the simplified refractive index for the eye (n') is 1.333. The refractive power of this reduced schematic eye is 60.0 D, with its principal plane at the front surface of the cornea.

Abbe’s refractometer, by temperature of 33 °C for aqueous, and 36 °C for vitreous, as it’s in human eye. In the principle of these results, the authors calculated the new values of cardinal points for the eye, and compared with Gullstrand’s opti-cal schematic eye. So, the refractive power for the eye F= 59.98 D, first focal length f First, according to the Gullstrand eye model, the AL of the eye globe is 24.38 mm, and other modified schematic eyes and investigation results have shown this length to be around 24 mm [16, 17].
