The glands of Moll are named after Dutch oculist Jacob Anton Moll (1832–1914). Glands of Moll empty into the adjacent lashes. Glands of Moll and Zeis secrete sebum that keeps lashes supple.

Sealant performing these functions. A sealant may be viscous material that has little or no flow characteristics and which stay where they are applied; or they can be thin and runny so as to allow it to penetrate the substrate by means of capillary action. Anaerobic acrylic sealants (generally referred to as impregnants) are the most desirable, as they are required to cure in the absence of air, unlike surface sealants that require air as part of the cure mechanism that changes state to become solid, once applied, and is used to prevent the penetration of air, gas, noise, dust, fire,
