Reciprocal of lens power, and accounting for the index of refraction of the inside of the eye:
16+ Reduced Schematic Eye Model PNG. This is slightly shorter than the full schematic eye, which is. Reciprocal of lens power, and accounting for the index of refraction of the inside of the eye:

Later reduced to four surfaces since raytracing is time consuming. This extension is accomplished by allowing the model's single refracting surface to be a member of the family of ellipses with variable shape parameter (eccentricity). Introduced by franciscus donders, the reduced eye model replaces the several refracting bodies of the eye (the cornea, lens, aqueous humor, and vitreous humor).
Schematic eye models have been proposed in the literature, each listing slightly different values for the cardinal points atchison 2017.
Schematic illustration of gullstrand reduced eye model. 17mm + 5.5mm = 22.5mm. The estimated amount of the sa was modeled by a reduced schematic eye with an elliptical refracting surface 50, for which k = −0.43. 850 x 280 png 10 кб.
