Allvar Gullstrand received a Nobel prize for his work and, although the schematic eye was a major breakthrough at the time, advances in technology and tireless research since then means that 100 years on we can take a more advanced approach to lens design. reduced eye, Gullstrand simplified or Gullstrand-le Grand eye, Swiegerling eye can be described as ideal theoretical models due to their assumptions valid in the paraxial domain [5], [8-9], [11-12]. The Arizona eye model that was used also in the present study is one of the recently developed theoretical eye model and far the most comprehensive Allvar Gullstrand, 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.

With the foveola 5.38 Optical modelling was based on ray tracing and manipulation of parameters of a Gullstrand reduced model eye. Results: There was a myopic shift in mean MSE with age (6-7 years +0.87 D, 12-13 years -0.06 D and 18-25 years -1.41 D), associated with an increase in mean AXL (6-7 years 22.70 mm, 12-13 years 23.49 mm and 18-25 years 23.98 mm). The formulas usually found in the literature only apply to the “reduced eye” meaning the performance of the eye within one degree of the optical axis. This is the region where the performance can be calculated reasonable correctly using “thin lens” optical equations. The formula of Le Grand, and of Gullstrand are for the reduced eye.

In the principle of these results, the authors calculated the new values of cardinal points for the eye, and compared with Gullstrand's optical schematic eye. So, the refractive power for the eye F = 59.98 D, first focal length f1 = -16.67 mm and second focal length f2 = +22.27 mm Reduced schematic eyes

Cornea represented as the only source of refractive power of the eye.

Lens is completely neglected.

Gullstrand #1 Exact Eye It is for reference purposes, to show how multiple surfaces can be reduced systemmatically to a single thin lens equivalent Reduced Eye Simplifications: The reduced schematic eye treats the eye as if it were a single refracting element consisting of an ideal spherical surface separating two media of refractive indices of 1.00 and 1.33.

Theoretically, it has only one refractive surface of anterior surface of cornea, and the equivalent axial length of eye ball. In this study, Gullstrand reduced eye model is used for the calculation of aberration by taking the geometrical shape of The Schematic Eye of Gullstrand or the Reduced Eye of LeGrand, are technically based on a paraxial optical analysis. This paraxial analysis only applies to angles less than 1.0 degrees from the optical axis. However, the paraxial analytical technique is frequently used to get an estimate of the real case. With the foveola 5.38 Optical modelling was based on ray tracing and manipulation of parameters of a Gullstrand reduced model eye. Results: There was a myopic shift in mean MSE with age (6-7 years +0.87 D, 12-13 years -0.06 D and 18-25 years -1.41 D), associated with an increase in mean AXL (6-7 years 22.70 mm, 12-13 years 23.49 mm and 18-25 years 23.98 mm).

Gullstrand schematic eye: The exact schematic eye was based on his very precise measurements on the human eye. Gullstrand är ett svenskt släktnamn vars äldste kände stamfader är Nils Olofsson, född i slutet av 1600-talet.Han var trädgårdsmästare först vid egendomen Ek i Eks socken i Västergötland, sedan från 1724 vid Sjöberg i Björsäters socken i samma landskap. Allvar Gullstrand was a reputed Swedish ophthalmologist and optician whose research on light-refracting technique of the eye won him the ‘Nobel Prize for Physiology or Medicine’ in 1911.

The formula of Le Grand, and of Gullstrand are for the reduced eye. With these advances in instrumentation, Gullstrand developed an authoritative optical model of the eye composed of six spherical refracting surfaces, two for the cornea and four for the crystalline lens. As shown in Figure 1, the lens is seen as a central double convex core surrounded by a cortex that has a lower index of refraction.
