The transparent membrane which surrounds the lens of the eye. [Dorian_AF, Elsevier's_encyclopaedic_dictionary_of_medicine, Part_B:_Anatomy_(1988)_Amsterdam_etc.:_Elsevier][VHOG]
(...) we reach the inescapable conclusion that the last common ancestor of jawless and jawed vertebrates already possessed an eye that was comparable to that of extant lampreys and gnathostomes. Accordingly, a vertebrate camera-like eye must have been present by the time that lampreys and gnathostomes diverged, around 500 Mya (reference 1); Although the eye varies greatly in adaptative details among vertebrates, its basic structure is the same in all. The human eye is representative of the design typical for a tetrapod. (...) A watery aqueous humor fills the spaces in the eye in front of the lens (...) (reference 2).[well established][VHOG]
synthesized by the lens epithelium and its main components are Type IV collagen and sulfated glycosaminoglycans (GAGs). [Wikipedia:Capsule_of_lens
FMA classifies this is a capsule and hence an organ part. In contrast we classify this as acellular
