There are many infections that affect different parts of the eye. The most common types of eye infections can be as result of viral, parasitic, bacterial and fungal infections. These infections require different types of eye drops for treatment.
Conjunctivitis is a commonly known type of eye viral infection that is very contagious and it's often known as “ocular herpes” or “pink eye”. Acanthamoeba is a parasitic infection that is caused by certain parasites found in the soil or water that can invade your eye from a contact surface. Bacterial infections commonly occur after complicated eye surgery or trauma.
Eye drops can be prescribed by the doctor or purchased at the pharmacy. There are many eye drops that are available over the counter depending on what they are going to be used for. However, if you have an eye infection or are experiencing problem with your vision, it is important to seek a doctor’s advice before buying any eye drops. Serious eye problems require immediate diagnosis and treatments which can only be provided by an eye doctor.
Some eye drops are issued only when the patient has a doctor’s prescription. These types of eye drops are specialized for certain types of eye ailments and most of them are prescribed for glaucoma, bacterial infections or after eye surgery.
Preservatives can be added to the eye drops for the purpose of eradicating any presence of bacteria. People who are either allergic or have sensitive eyes may experience some reactions such as soreness, redness and irritation due to the preservative. You can also find eye drops that are preservative free and they come in single doses. You only use them once and discard. This type of eye drop is more costly compared to the one with preservative.
