Scleral lenses can affect a range of anterior segment structures including the eyelids and the tears. The eyelids, consisting of the outer skin layer, the middle tarsal plate, and the posterior palpebral conjunctiva, provide physical protection and house the meibomian glands and cilia which have important and unique functions. Tears consist of a mix of aqueous, mucus, and lipidomic components that serve vital functions of lubricity, protection, and nourishment to the ocular surface. Both the eyelids and the tear film interact directly with scleral lenses on the eye and can affect but also be impacted by scleral lens wear. The purpose of this paper is to review the anatomy and physiology of the eyelids and tear film, discuss the effects and impacts of the scleral lenses on these structures, and identify areas that require further research.

巩膜镜片可影响一系列眼前节结构，包括眼睑和泪液。由外皮层、中跗骨板和后睑结膜组成的眼睑提供物理保护，并容纳具有重要和独特功能的睑板腺和纤毛。眼泪由水性、粘液和脂质组学成分组成，它们对眼表起到润滑、保护和滋养等重要功能。眼睑和泪膜都直接与眼睛上的巩膜镜片相互作用，可以影响巩膜镜片的佩戴，但也受其影响。本文的目的是回顾眼睑和泪膜的解剖学和生理学，讨论巩膜镜片对这些结构的影响，并确定需要进一步研究的领域。
