The eye is a critical organ of the human body. It has a special anatomy to perform the highly sophisticated function of vision. The human eye has multiple components, divided into three layers. The first layer entails the cornea: the transparent front part; and the sclera: the white opaque part. The second layer has –among other structures- the iris; the colored segment of your eye. Then, the last layer that contains the retina; the section having photosensitive structures that respond to light and consequently vision. The eye –being an outer exposed organ- is likely to get infected. Infections affect many structures of the eye and vary according to their cause, severity, and treatment. Different kinds of organisms can attack the eye; bacteria, viruses, fungi, and parasites. Symptoms of eye infections differ and sometimes overlap, so consider seeking medical advice if you don’t feel well. Seek for eye specialist to raise your issue on whatever eye problem you are encounter, just like in your teeth we look for the dental specialist to fix your dental problems.
