Light microscopy of fibres in the lens of the eye. The lens is covered on its front surface by a capsule and epithelial cells. At the sides of the lens, the epithelial cells gradually elongate and then lose their nuclei, forming many thousands of long, thin tightly packed fibres seen here in cross-section. Each fibre contains a high abundance of transparent proteins called crystallins. Occasional fibres show a nucleus but eventually these disappear during lens development. The earliest lens fibres made in fetal life lie in the centre of the lens where they are retained. New lens fibres are added to the inner layers and may be formed throughout life.
