Theoretical calculations were performed to predict how the light scattering intensity would change with changes in concentration in the gel state. The theory of light scattering was applied to a random distribution of hard spheres.

By the addition of suitable reflectors the concentration of a lens can be increased to the thermodynamic limit, which is equivalent to an ƒ-number of one half. ... Such lens-mirror combinations are useful whenever concentration rather than image formation is important, for example, in radiation detectors and solar...

The postulated mechanism has been one of transcorneal evaporation of water increasing the concentration of the aqueous and osmotically affecting the lens. In this experiment, changes in the colligative properties of hamster aqueous were measured as related to corneal exposure and the development of lens opacity.
