There are a lot of ways in which a person can end up suffering from eye infections. However, in almost all cases the cause of an eye infection is a harmful microorganism that infects the eye. This microorganism can be viral, fungi or bacteria.
It is important that people go straight to the eye doctor if they even suspect of an eye infection. The main reason why that is so, is because certain eye infections can lead to blindness if they are not properly treated in time. Out of all the eye infections that a person may end up suffering from, conjunctivitis and sty are the most common. Apart from these two, some of the other eye infections that may occur are blepharitis, trachoma, corneal ulcer and keratitis. According to the experts, people who wear contact lenses are more prone to suffering from eye infections than other people. The main reason why that is so, is because of the buildup of bacteria that occurs due to wearing the lenses without proper disinfection. Just like with all the other part of the body, the eyes are more likely to get infected when their defenses become weak. However, people need not worry too much since there are not that many eye infections that are dangerous but it is essential that a person receives proper eye treatment on time.
Symptoms of conjunctivitis
The most obvious symptom of this infection is the red color of the eye or the inner eyelid. It is not always the case that both eyes are affected. Apart from the red color, some of the other symptoms are frequent flow of tears and thick crust or yellow discharge over the eyelashes. Itching is present as well. A person who suffers from conjunctivitis will be a lot more sensitive to light.
Symptoms of sty
The most common symptoms of this eye infection are itching and irritation. Apart from these two, a person suffering from sty will have a big lump on either the top or bottom eyelid. The first symptoms that occur with this infection are redness, tenderness and pain. If left untreated, a person may experience swelling and increased light sensitivity.
Symptoms of trachoma
The early symptoms of trachoma are not that different from other eye infections are they are redness, watery eyes, swollen eyelids and light sensitivity. If left untreated, a person will experience tiny red lumps in the eyelids. At a much later stage of this infection, eye pain, corneal scarring and even dimming vision are possible.
