Escudero-Sanz and Navarro wide-angle schematic eye.

This module does not provide an eye model class, because the default eye model in visisipy is already based on the Navarro geometry and materials.

Classes

NavarroGeometry

Geometric parameters of the Navarro wide-angle schematic eye.

Module Contents

class visisipy.models.catalog.navarro.NavarroGeometry(**surfaces: visisipy.types.Unpack[visisipy.models.geometry.EyeModelSurfaces])

Bases: visisipy.models.geometry.EyeGeometry[visisipy.models.geometry.StandardSurface, visisipy.models.geometry.StandardSurface, visisipy.models.geometry.Stop, visisipy.models.geometry.StandardSurface, visisipy.models.geometry.StandardSurface, visisipy.models.geometry.StandardSurface]

Geometric parameters of the Navarro wide-angle schematic eye.

This schematic eye is based on the Navarro model as described in [1]. Sizes are specified in mm.

Attributes:

cornea_frontStandardSurface

The front surface of the cornea.

cornea_backStandardSurface

The back surface of the cornea.

pupilStop

The pupil of the eye.

lens_frontStandardSurface

The front surface of the lens.

lens_backStandardSurface

The back surface of the lens.

retinaStandardSurface

The retina of the eye.

Examples

Use the default Navarro geometry:

>>> from visisipy import NavarroGeometry
>>> geometry = NavarroGeometry()

Create a Navarro geometry with a custom retina:

>>> geometry = NavarroGeometry(
...     retina=StandardSurface(radius=-12.5, asphericity=0.5)
... )

Create a default Navarro geometry and change only the lens back radius:

>>> geometry = NavarroGeometry()
>>> geometry.lens_back.radius = -5.8
