A key element of contact lens practice involves clinical evaluation of anterior eye health, including the cornea and limbus, conjunctiva and sclera, eyelids and eyelashes, lacrimal system and tear film. This report reviews the fundamental anatomy and physiology of these structures, including the vascular supply, venous drainage, lymphatic drainage, sensory innervation, physiology and function. This is the foundation for considering the potential interactions with, and effects of, contact lens wear on the anterior eye. This information is not consistently published as academic research and this report provides a synthesis from all available sources. With respect to terminology, the report aims to promote the consistent use of nomenclature in the field, and generally adopts anatomical terms recommended by the Federative Committee for Anatomical Terminology. Techniques for the examination of the ocular surface are also discussed.

隐形眼镜实践的一个关键要素涉及前眼健康的临床评估，包括角膜和角膜缘、结膜和巩膜、眼睑和睫毛、泪道系统和泪膜。本报告回顾了这些结构的基本解剖学和生理学，包括血管供应、静脉引流、淋巴引流、感觉神经支配、生理学和功能。这是考虑隐形眼镜佩戴对前眼的潜在相互作用和影响的基础。此信息并非始终作为学术研究发表，本报告提供了所有可用来源的综合。在术语方面，该报告旨在促进该领域术语的一致使用，并且一般采用解剖术语联邦委员会推荐的解剖术语。还讨论了检查眼表的技术。
