The camel eye shows some distinct features such as a pigmented peripheral cornea, a remarkably thickened Descement membrane, and endothelial-lined pectinate ligament, a cleft ciliary body, long ciliary processes, a horizontally oval pupil with well-developed corpora nigra and a holangiotic retina. Some of these are characteristic of horses, cattle and sheep, whereas others are more commonly found in lower mammals such as the rabbit. The reason for this staggered evolution in the development of the camel eye remains obscure.
骆驼的眼睛呈现出一些独特的特征，比如色素沉着的周边角膜、明显增厚的Descemet膜、内皮衬里的梳状韧带、裂开的睫状体、长长的睫状突、具有发育良好的黑质的水平椭圆形瞳孔以及全血管性视网膜。其中一些特征是马、牛和羊所特有的，而其他一些特征在诸如兔子等低等哺乳动物中更为常见。骆驼眼睛发育过程中这种交错进化的原因仍然不明。
