The type of conjunctivitis you have will inevitably determine the type of treatment you’ll need. There are four many types including viral conjunctivitis, bacterial conjunctivitis, allergic conjunctivitis, and irritation caused conjunctivitis. Viral Conjunctivitis Conjunctivitis can be caused by a plethora of different viruses including Covid-19, the common cold, herpes simplex virus, and varicella-zoster virus. In the case of viral conjunctivitis, you will likely experience the symptoms of a respiratory illness as well. Viral conjunctivitis is extremely contagious and is often spread at schools and daycare centers. Bacterial Conjunctivitis Bacterial conjunctivitis is caused by the following bacterias: streptococcus pneumonia, moraxella catarrhalis, chlamydia trachomatis, neisseria gonorrhea, staphylococcus aureus, and haemophilus influenza. Similar to viral conjunctivitis, bacterial conjunctivitis is very contagious and can spread to either one or both eyes. Allergic Conjunctivitis Allergic conjunctivitis affects both eyes and is caused by an increase in an antibody known as immunoglobulin E. This antibody can cause the mucous lining in your eye to release histamines which in turn, causes symptoms of pink eye. Allergic conjunctivitis symptoms include red eyes, inflammation, nasal discharge, eye discharge, sneezing, itchy eyes, and burning. Irritation Caused Conjunctivitis Conjunctivitis caused by irritation may cause symptoms like mucous discharge, watery eyes, and irritation. Chemical splashes will need to be resolved through flushing and cleansing. A foreign object in your eye that causes conjunctivitis can be small or large. Bigger objects need to be removed by a medical professional. A smaller object can be removed at home, but if the infection persists, you’ll need to see your doctor. This will prevent any potential scratches and permanent eye damage.
