Lens aging: Effects of crystallins [PDF]
Biochimica et Biophysica Acta (BBA) - General Subjects, 2009 The primary function of the eye lens is to focus light on the retina. The major proteins in the lens--alpha, beta, and gamma-crystallins--are constantly subjected to age-related changes such as oxidation, deamidation, truncation, glycation, and methylation. Such age-related modifications are cumulative and affect crystallin structure and function. With

High-Performance PVC Gel for Adaptive Micro-Lenses with Variable Focal Length. [PDF]
, 2017 This paper presents a bio-inspired adaptive micro-lens with electrically tunable focus made of non-ionic high-molecular-weight polyvinyl chloride (PVC) gel. The optical device mimics the design of the crystalline lens and ciliary muscle of the human eye.

Human Lens β-Crystallin Solubility [PDF]
Journal of Biological Chemistry, 2000 The human lens is composed primarily of water and proteins called crystallins. Insolubility of these crystallins is correlated with aging and cataractogenesis. The alpha-crystallins have chaperone-like activity in maintaining the solubility of denatured beta- and gamma-crystallins. One established test of this chaperone activity is the ability of alpha-
