MOBILE WORLD CONGRESS, BARCELONA, Feb. 24, 2014 â SanDisk Corporation (NASDAQ: SNDK), a global leader in flash storage solutions, today announced the new 128GB 2 SanDisk Ultra Â® microSDXCâ¢ UHS-I memory card, the worldâs largest capacity microSD card.
It is composed of three concentric layers (also called coats) with different structures and functions. The tough outermost layer of the eye is known as the fibrous layer and is composed of two fused but physically quite different structures: Sclera â white of the eye. Cornea â window of the eye.
A tough white covering called the sclera protects the eye. Part of the white sclera can be seen in the front of the eye. A clear, delicate membrane called the conjunctiva covers the sclera. At the front of the eye is the cornea. The cornea is the clear part of the eyeâs protective covering. It allows light to enter the eye. The iris is the colored part of the eye that contracts and expands so the pupil can let just the right amount of light into the eye. The light is directed by the pupil to the lens. The lens focuses the light onto the retina (lining the back of the eye).
