Eye lenses are composed of a series of molecules called keratinocytes, which are composed of water. These proteins are the main constituents of the cornea, and they help the eyes focus on distant objects. They are made of keratin. The keratinocytes have high concentrations of crystallin proteins, which helps them korean colored lenses AU maintain transparency. The keratinocytes also contain all the large cell structures and organelles. The bulk of the eye lens is not cellular and has no metabolic activity or blood supply.
A lens’s crystalline structure is based on a complex chain of amino acids, which are arranged in a specific way. The smallest unit, the a-crystallin, is the most abundant protein in the lens, which is the basis of its opacity. These proteins are essential for the health of the lens, but they also contribute to the haziness and blurred vision that can occur with cataract surgery.
Cataract formation is a result of protein damage. Highly stressed proteins randomly self-associate into aggregates, which increase in size and serve as nucleation sites for further growth. These protein aggregates within the lens compromise the transparency and uniformity of the lens’ medium, resulting in light scattering and loss of visual acuity. The a-crystalin is the best material for eye lenses, while the b-crystallin is the second most abundant.
