Introduction
Red eye may be caused by allergies or bacterial infection. There are many possible causes of red eye. First, “red eye” refers to acute conjunctivitis, which can manifest as: (1) nonspecific inflammation due to bacterial infection; (2) allergic inflammation triggered by allergens; or (3) localized, noninfectious inflammation resulting from prolonged poor eye habits. When experiencing red eye, there is no need for excessive anxiety.

Depending on the underlying cause, acute conjunctivitis can be classified into bacterial conjunctivitis, viral conjunctivitis, and conjunctivitis induced by other factors. Treatment of acute conjunctivitis primarily targets the causative factor and is mainly local; systemic medications may be required when necessary. Bacterial conjunctivitis is primarily treated with antibiotics. So, how does “pink eye” develop?

How Does Pink Eye Develop?

Pink eye may result from either allergic reactions or bacterial infection. There are numerous potential causes. First, “pink eye” refers to acute conjunctivitis, which may manifest as: (1) nonspecific inflammation caused by bacterial infection; (2) allergic inflammation triggered by allergens; or (3) sterile, localized inflammation resulting from prolonged unhealthy eye habits. When experiencing pink eye, there is no need for excessive anxiety. Prompt consultation with an ophthalmologist is recommended for examination and accurate diagnosis of the specific type of conjunctivitis, followed by targeted, etiology-specific treatment.

If the condition is caused by bacterial, viral, or mycoplasmal infection, appropriate topical antibiotic eye drops—selected based on pathogen sensitivity—may be used. If allergic in origin, sodium cromoglicate eye drops or similar anti-allergic agents are generally prescribed.

In daily life, patients should maintain a positive mindset, actively cooperate with their physicians during treatment, adhere strictly to prescribed dosages and schedules for medication, and pay attention to routine eye care—thus facilitating prompt improvement of symptoms.
