WebEye Lens Protector. Cataracts are cloudy spots in the otherwise crystal-clear lens of the eye that are formed when lens tissues break down, or when lens proteins clump together. 4,7 They cause blurred vision, a faded appearance of colors, and increased sensitivity to glare and bright lights. 7. Cataracts were once thought to be an inevitable consequence of aging. WebJan 15, 2024 · The crystallins (α, β and γ), major constituent proteins of eye lens fiber cells play their critical role in maintaining the transparency and refractive index of the lens. Under different stress factors and with aging, …
WebThe name "crystallin" is rather ironic. Crystallins have been perfected by evolution expressly for their ability not to form crystals. The eye lens needs to be a highly concentrated solution, but it needs to avoid small crystals … WebAbstract. β L -crystallin aggregation due to oxidative damage in the presence of H 2 O 2 and ferric chloride was studied in-vitro under conditions close to physiological. It was shown that the protein aggregation characterized by the nucleation time and the aggregation rate significantly depended on the composition of the isoosmotic buffers ...
