Allergic Conjunctivitis: Understanding Inflammation Triggered by Allergies Allergic conjunctivitis can be a result of allergies or, in some instances, infections. The reason allergies often target the eyes is because they have a rich network of blood vessels that react to allergens. Your eyes are in direct contact with the external environment.   When you encounter allergens like pollen, dust, pet dander, medications, or cigarette smoke, these substances dissolve in your tears and interact with the conjunctiva. This conjunctiva generates antibodies known as IgE (Immunoglobulin E). When allergens bind to these antibodies, it sets off an allergic response. This leads to itching, redness, and watery eyes. Your skin around the eyes typically remains unaffected, and your vision remains clear. It's advisable to avoid wearing contact lenses during this time, as they could raise the risk of bacterial infections.   Types of allergic conjunctivitis:   Conjunctivitis: This is the most prevalent form of allergic conjunctivitis and is often accompanied by symptoms like a runny nose. Key indicators include itchy, watery eyes, usually affecting both eyes, and the severity may fluctuate with the seasons. Perennial Allergic Conjunctivitis: This type is a year-round allergic response and is less common. The symptoms are typically milder compared to the first type. Atopic Keratoconjunctivitis: This form is often linked with skin issues such as eczema around the eyes and face. Symptoms encompass redness, itching, and excessive tearing. The hallmark sign is intense eye itching. In the case of an infection, you might experience pain and a mucous or pus-like discharge. Inflammatory changes may affect the conjunctiva and cornea.   Preventing allergic conjunctivitis: To ward off allergic conjunctivitis, it's vital to minimize your exposure to allergens. This includes avoiding places with blooming flowers, dusty environments, cigarette smoke, and pets.   Self-care for allergic conjunctivitis: If you're experiencing eye irritation and suspect allergies, take immediate steps to avoid allergens. You can use artificial tears to reduce swelling and flush out allergens. Applying a cold compress can help diminish swelling. Over-the-counter antihistamines can offer relief. If self-care doesn't alleviate your symptoms, it's wise to seek advice from a healthcare professional who may prescribe allergy eye drops.   Avoiding allergens: In certain cases, rinsing your eyes with a saline solution might be necessary. Cold compresses can help reduce swelling. You may be prescribed eye drops to constrict blood vessels and reduce inflammation. In severe cases, steroid eye drops are employed.        

Safe Songkran Celebration - Protecting Your Eyes from Infections Eyes are vulnerable to various infections, particularly when exposed to impure water during the Songkran festival. Water used for the festivities may contain harmful bacteria, viruses, or even fungi. Before joining the water splashing fun, it's crucial to examine the water you'll be using for any contamination like dust, debris, sand, or impurities.   Eye Conditions Arising from Unclean Water and Contaminants Conjunctivitis (Pink Eye): Symptoms include redness, itching, eye discharge, excessive tearing, and inflammation of the white part of the eye. It can be caused by allergies or infections, including bacteria or viruses transmitted through contaminated water. Corneal Abrasions and Ulcers: The cornea, the clear front surface of the eye, can be scratched due to foreign objects or improper use of contact lenses. Severe cases can lead to corneal ulcers when infections occur. Stye: Styes are inflamed oil glands on the eyelid. When these glands get blocked, they can become painful and red. Red Eye: This condition includes symptoms like a red and swollen white of the eye, excessive eye discharge, itching, eye pain, sensitivity to light, and blurred vision. If you get water or foreign objects in your eye, rinse with clean water. Afterward, observe if the symptoms improve; if not, consult a doctor within 1-2 days.   Precautions for Songkran Celebration Before participating in the water festivities, ensure that the water is sufficiently clean and free from impurities. If something foreign enters your eye, do not rub it as this may dislodge your cornea. Rinse your eye with clean water and seek medical attention if necessary. If contaminated water causes eye irritation, such as redness, itching, or tearing, rinse your eyes with flowing clean water. For contact lens wearers, it's not recommended to wear lenses while participating in water activities to prevent infections. After the Songkran celebration, check for any signs of eye discomfort or redness. If you experience eye irritation that doesn't improve, consult an eye doctor.   In Summary While celebrating Songkran, take steps to protect your eyes from infections caused by impure water and contaminants. By following these precautions, you can enjoy a safe and joyful Songkran festival without compromising your eye health.
