Crystalline lens imaging with a slit-scanning system [PDF]
, 2011 [Introduction] The human crystalline lens plays a fundamental role on the retinal image quality. The ability of the lens to change its shape and, consequently, the total refractive power of the eye, during accommodation, enables one to focus objects at a

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.
