Lens of the eye,light micrograph
Lens of the eye. Light micrograph of a section through the lens from a human eye. The lens consists of thousands of precisely aligned stacks of fibres' seen here end-on,that were formerly elongated epithelial cells but during development,lose their nuclei and organelles. Some lens fibres show nuclei,indicating ongoing early development. Lens fibres contain a very high concentration of crystalline proteins that,together with the lack of a nucleus or organelles,are largely transparent to light. Interlocking and alignment of the curved lens fibres not only refracts light but the fibres also vary in curvature as the lens,being flexible,changes in shape to focus on near or far objects. Magnification: x111,when printed 10 centimetres
