    Most people who get eye infections get viral Pink Eye and viral Keratitis.

    Redness, swelling, discharge, pain, and photophobia (sensitivity to light) are some symptoms of viral Conjunctivitis.

    Three types of viruses can cause Pink Eye: Adenovirus, Herpes Simplex, and Enterovirus.

    According to studies, redness, tearing, itching, and irritation are all signs of viral Keratitis.

    The Herpes Simplex Virus (HSV) causes viral Keratitis. If it is not treated, HSV can easily lead to blindness.

    Since antibiotics don’t work on viral eye illnesses, doctors often prescribe antiviral medicines and artificial tear drops to help ease symptoms.

    Fungal eye infection

    The Centers for Disease Control and Prevention (CDC) says fungal eye diseases are rare.

    Still, these diseases can be very bad; you might get them from plant parts like sticks or thorns.

    The cornea often gets infected, which causes fungal Keratitis and redness.

    Fungal infections can sometimes happen inside the body, leading to Endophthalmitis, an illness inside the eye.

    Fungi like Fusarium, Aspergillus, and Candida are often linked to these illnesses.

    When you get a fungal eye infection, it can weaken your immune system and cause pain, redness, and trouble seeing.

    Fact:
    Endophthalmitis: It is characterized as inflammation within the inner layers of the eye due to the presence of infectious agents inside the eye, leading to the release of fluids within the eye.

    Bacterial eye infection

    The most common bacterial eye infections are Pink Eye, Keratitis, and Stye.

    Bacterial Pink Eye causes irritation, burning, swelling, and thick, sticky discharge.

    These bacteria include Staphylococcus Aureus, Streptococcus Pneumoniae, and Haemophilus Influenzae.

    Pus- and oil-filled styes are uncomfortable eyelid pimples. Staphylococcus bacteria cause infection of the eye gland.

    According to the American Academy of Ophthalmology, Staphylococcus, Streptococcus, and Pseudomonas bacteria cause most bacterial Keratitis.

    Doctors often prescribe antibiotic eye drops for bacterial eye infections.

    Warning:
    Consult a doctor before taking any prescription medicine because your doctor can guide you with the appropriate dosage to help you avoid side effects.

    Parasitic eye infection

    Some people get an eye infection called Acanthamoeba Keratitis because of a parasite called Acanthamoeba.

    If you have this parasitic eye infection, you may experience eye pain, feel like something is in your eyes, have blurred vision, and tear a lot.

    This infection targets the cornea and has the potential to result in permanent vision impairment.

    Conclusion

    In conclusion, understanding the various types of eye infections is important for effective treatment and quick recovery. 

    Viral, bacterial, fungal, and parasitic eye infections have different symptoms and complications. 

    While viral infections like Pink Eye and Keratitis are commonly encountered, bacterial infections manifest as Pink Eye, Keratitis, and Styes. 

    Fungal eye diseases, though rare, can be severe, affecting the cornea and sometimes leading to Endophthalmitis. 

    Acanthamoeba Keratitis, a parasitic eye infection, threatens vision and necessitates prompt attention. 

    Recognizing the signs and causes of these eye infections enables timely intervention, emphasizing the importance of informed eye care practices.
