Introduction
June is a peak season for conjunctivitis. Conjunctivitis is a seasonal ocular infectious disease, with peak incidence occurring primarily in spring and summer. During these two seasons, bacteria and viruses enter their peak reproductive periods, making the eyes more susceptible to bacterial or viral invasion and subsequent infection. In particular, during summer, many people enjoy visiting public swimming pools.

　　Conjunctivitis (commonly known as “pink eye”) is a common ocular infectious disease—but it is not something to fear. As long as proper eye hygiene is maintained—such as avoiding sharing handkerchiefs or using handkerchiefs that have touched the face or eyes—the risk of infection can be significantly reduced. Patients diagnosed with conjunctivitis should not panic; instead, they should keep their eyes clean and take prescribed medications regularly. Is June a peak season for conjunctivitis?

　　Is June a peak season for conjunctivitis?

　　Yes, June is indeed a peak season for conjunctivitis. This ocular infectious disease exhibits distinct seasonal patterns, with highest incidence occurring during spring and summer. During these seasons, bacteria and viruses proliferate more actively, making the eyes more susceptible to bacterial or viral invasion and subsequent infection. In particular, many people enjoy visiting public swimming pools in summer. If an individual with active conjunctivitis swims in such a pool, their ocular secretions may contaminate the water and infect others. Thus, summer—especially June—is considered a high-risk period for conjunctivitis, largely due to hot weather prompting widespread swimming activity.

　　Pool water serves as an ideal transmission medium for conjunctivitis, underscoring the importance of enhanced eye protection. Conjunctivitis often has a prolonged course and complex etiology; if left untreated or inadequately managed over time, it may lead to multiple complications, significantly impacting patients’ quality of life. Children with conjunctivitis commonly experience symptoms including ocular pruritus (itching), increased discharge, redness and swelling of the eyes, conjunctival hyperemia (congestion), epiphora (excessive tearing), photophobia (light sensitivity), conjunctival edema, or subconjunctival hemorrhage.

　　In daily life, patients should maintain a positive mindset and actively cooperate with their physicians’ treatment plans. It is essential to take medications on schedule and at the prescribed dosage, while also adhering to appropriate daily care measures to facilitate prompt symptom improvement. We hope this information proves helpful to you.

What Causes Pink Eye?
Conjunctivitis has numerous etiologies, primarily involving diminished host immunity, rendering individuals more susceptible to external environmental influences—especially young patients, those recently recovered from severe illness, those with chronic diseases, or those with prolonged medication histories. Conjunctivitis is typically an acute, infectious, inflammatory ocular disease caused by pathogens such as enteroviruses, adenoviruses, or “superbugs,” which exhibit heightened virulence and activity.

Does pink eye require dietary restrictions?
Patients with conjunctivitis should avoid certain foods. Specifically, they should avoid spicy and irritating foods, greasy foods, and seafood such as fish, shrimp, and crab. Patients are advised to quit smoking and abstain from alcohol, and to consume more vegetables and fruits rich in vitamins. During treatment with herbal remedies for conjunctivitis, patients should pay attention to periorbital care and avoid rubbing their eyes with unclean hands.

Ophthalmology Knowledge: Is Conjunctivitis Contagious?
Ophthalmological Knowledge Explanation: Conjunctivitis (commonly known as “pink eye”) is contagious. It spreads through contact transmission, which can be categorized into direct and indirect contact. Infection may occur if you touch an infected person’s eyes and then touch your own eyes. Similarly, if an infected person touches their own eyes and then touches other objects, those surfaces may become contaminated.

Can regular table salt be used to wash away conjunctivitis?
Ordinary table salt must not be used to wash away conjunctivitis (“pink eye”). While saline solution may be used to rinse the eyes, it must be isotonic saline—specifically, 0.9% sodium chloride injection, a solution commonly used in clinical practice. Conjunctivitis typically presents with increased ocular discharge; therefore, non-irritating irrigating solutions—such as 3% boric acid solution or 0.9% sodium chloride injection—may be used to irrigate the conjunctival sac.

Differences Between “Red Eye Disease” and Conjunctivitis
Conjunctivitis is an umbrella term for a group of disorders, including bacterial conjunctivitis, viral conjunctivitis, fungal conjunctivitis, and allergic conjunctivitis. “Red eye disease” is another name for bacterial conjunctivitis; thus, red eye disease is a subtype of conjunctivitis—this distinction clarifies the difference between “red eye disease” and conjunctivitis. Clinical manifestations of conjunctivitis include conjunctival hyperemia, edema, and increased ocular discharge. Patients should seek comprehensive evaluation at a qualified medical institution.

What causes red, watery eyes in conjunctivitis?
For conjunctivitis (“pink eye”) with red, watery eyes, symptomatic treatment with antiviral or antibacterial medications is recommended. If conjunctival hemorrhage occurs in this context, it is typically caused by eye rubbing or vigorous wiping, leading to rupture of conjunctival blood vessels. Subconjunctival hemorrhage is generally benign and rarely leads to serious complications—similar to a skin abrasion—and usually resolves spontaneously without worsening the underlying condition.

Differences Between Acute Keratitis and Conjunctivitis
There are certain distinctions between conjunctivitis (“pink eye”) and keratitis. Conjunctivitis is primarily caused by various pathogens, leading to conjunctival hyperemia and edema, along with copious discharge. Keratitis, by contrast, predominantly affects the cornea—the transparent, dome-shaped front surface of the eye (not the “black part,” which refers to the pupil or iris). While keratitis can indeed cause redness of the eye (and thus may be considered a type of “red eye”), it may also result in corneal damage. However, unlike conjunctivitis, keratitis does not typically spread widely as an epidemic; such widespread transmission is uncommon.

Can you get infected by looking at the eyes of a patient with conjunctivitis?
Looking at the eyes of a patient with conjunctivitis will not cause infection. Conjunctivitis is typically transmitted through direct or indirect contact—for example, a person with conjunctivitis may infect others by touching their own eyes and then transferring eye secretions to surfaces or other individuals. Additionally, sharing towels or washbasins with a person who has conjunctivitis may also lead to infection. Some individuals with conjunctivitis may first touch their own eyes and then inadvertently spread the infection.
