The white part of the eye is the sclera. The sclera is the outer covering of the eyeball, which is made of a very tough material. It also contains blood vessels that deliver blood to the sclera. The cornea is a transparent dome that is located in front of the colored part of your eye. It helps with the focusing of the eye when light enters. It is a very difficult part to see because it is made of a clear tissue. Think of the cornea as a window the person's eye sees through.
眼睛的白色部分是巩膜。巩膜是眼球,它由非常坚硬的材料组成。该部分也包括了向巩膜输送血液的血管。角膜是位于眼睛的彩色部分前的透明圆顶。它有助于眼睛对光聚焦。这是一个非常难观察到的部分因为它的是由透明组织组成。可以把角膜看作人眼的一扇窗户。
Located behind the cornea is the iris, which is the colorful part of the eye. There are muscles attached to the iris that change its shape, which controls the amount of light going through the pupil. The pupil is the black circle in the middle of the iris and lets the light enter the eye. The pupils adjust to the light by opening wider when more light is needed, and shrinks when there is plenty of light available. The anterior chamber is the space between the iris and cornea, which is filled with a transparent fluid keeping the eye healthy.
位于角膜后面的是虹膜,这是眼睛色彩丰富的一部分。与虹膜相连的肌肉改变其形状从而控制进入瞳孔的光的量。瞳孔是虹膜中间的黑色圆圈,光线通过瞳孔进入眼内。瞳孔可以收缩,当需要更多的光线时,瞳孔扩张;当周围的光线十分充足,瞳孔紧缩。眼球前房在虹膜和角膜之间,前方中充满透明流体用来保护眼睛的健康。
