Provide a uniform interface to define, build and analyze various types of eye models, using abstractions that are relevant in a clinical context.\n2. Provide a collection of ready-to-use eye models, such as the Navarro model[^navarro], that can be customized at need.\n3. Provide an accessible interface to clinically relevant analyses on these models, such as off-axis refraction calculations.\n4. Modular design with support for multiple backends, both open-source and commercial.\n\n## Contributing\n\nVisisipy aims to be a community-driven project and warmly accepts contributions.\nIf you want to contribute, please email us (visisipy@mreye.nl) or [open a new discussion](https://github.com/MREYE-LUMC/visisipy/discussions).\n\n## Installation\n\nVisisipy can be installed through [`pip`](https://pypi.org/project/visisipy/):\n\n```bash\npip install visisipy\n```\n\nVisisipy is also available on [Conda Forge](https://anaconda.org/conda-forge/visisipy):\n\n```bash\nconda install -c conda-forge visisipy\n```\n\n## Example\n\n```python\nimport matplotlib.pyplot as plt\nimport seaborn as sns\n\nimport visisipy\n\n# Uncomment the following line to use the open-source Optiland backend instead of OpticStudio\n# visisipy.set_backend(\"optiland\")\n\n# Initialize the default Navarro model\nmodel = visisipy.EyeModel()\nmodel.geometry.pupil.thickness = 2.0\n\n# Build the model in OpticStudio\nmodel.build()\n\n# Perform a raytrace analysis\ncoordinates = [(0, 0), (0, 10), (0, 20), (0, 30), (0, 40)]\nraytrace = visisipy.analysis.raytrace(coordinates=coordinates)\n\n# Alternatively, the model can be built and analyzed in one go:\n# raytrace = visisipy.analysis.raytrace(model, coordinates=zip([0] * 5, range(0, 60, 10)))\n\n# Visualize the model\nfig, ax = plt.subplots()\nvisisipy.plots.plot_eye(ax, model.geometry, lens_edge_thickness=0.5)\n\nsns.lineplot(raytrace, x=\"z\", y=\"y\", hue=\"field\", ax=ax)\n\nplt.show()\n```\n\n## Documentation\n\nRead the full documentation at [visisipy.readthedocs.io](https://visisipy.readthedocs.io).\n\n[//]: # (References)\n[^navarro]: Escudero-Sanz, I., \u0026 Navarro, R.
