The term 'LAYER EYE' is composed of two words, 'LAYER' and 'EYE'. The first word, 'LAYER', refers to a thin sheet or coating of material, such as paint or fabric. The second word, 'EYE', refers to the organ of sight in humans and other animals. When combined, the term 'LAYER EYE' can refer to the uvea, which is the middle LAYER of the EYE. The uvea is composed of three parts: the iris, the ciliary body, and the choroid. It is responsible for controlling the amount of light entering the EYE and helps to protect the inner structures of the EYE.
