An exoteric geometric mechanics model of ocular accommodation is detailed to elucidate the main ideas of various ongoing modeling efforts. The present study derives solutions for the stretched state of the ocular lens as it might appear during accommodation by using simple geometric arguments and a volume constraint, rather than the more mathematically intensive theory of elasticity. Results show that geometric shapes similar to the lens will deform in a similar fashion. This implies that, while the true lens geometry is somewhat more complex, it should also follow these qualitative behaviors.
一个公开的眼睛调节几何力学模型被详细阐述，以阐明各种正在进行的建模工作的主要观点。本研究通过使用简单的几何论证和体积约束，而不是更具数学复杂性的弹性理论，得出了晶状体在调节过程中可能出现的拉伸状态的解。结果表明，与晶状体相似的几何形状会以类似的方式变形。这意味着，虽然真正的晶状体几何形状要复杂一些，但它也应该遵循这些定性行为。
