Tightening of these structures could block their ability to be moved by the ciliary muscles during accommodation

Changes in this molecule could selectively impair wavelength sensitivity at some frequencies 

Cataracts, which cause blurring and defocusing of the image, involve changes in this structure.

A block in this area impedes the flow of fluid in the eye and results in an increase in intraocular pressure

Length changes in this structure lead to common refractive errors

An increase in liquidity of this jelly happens with ageing and faster in myopic eyes
