Conjunctivitis, also referred to as pink eye, is an infection or inflammation of the conjunctiva, the translucent membrane that covers the white portion of the eyeball and lines the eyelid. Although it can affect people of various ages, this ailment is rather common, particularly in youngsters. Allergens, germs, viruses, and irritants can all be the reason. Redness in the whites of the eyes is one of the most obvious signs of conjunctivitis. The conjunctiva's dilated blood vessels are the cause of this redness. People may also feel as though their eyes are burning, itching, or have a grainy texture. A discharge, which can be clear, yellow, or greenish in color, may also come from the eye. The eyelashes may stay together as a result of this secretion, especially after sleeping.Common colds and other upper respiratory illnesses are frequently linked to viral conjunctivitis. It is extremely contagious and can be transmitted by touching contaminated surfaces or coming into direct contact with the secretions of an infected individual. On the other hand, a variety of bacteria, including those that cause respiratory and ear infections, can cause bacterial conjunctivitis. Additionally, it is communicable and can be shared directly. When the conjunctiva reacts to allergens like dust mites, pet dander, or pollen, allergic conjunctivitis develops. It often affects both eyes and is not communicable. Exposure to chemicals in cosmetics, smoking, or chlorine in swimming pools can all result in irritant conjunctivitis. It is also non-contagious and can affect one or both eyes.The etiology of conjunctivitis determines how you treat it. In a week or two, viral conjunctivitis normally goes away on its own, however artificial tears or cold compresses can help ease symptoms. To treat bacterial conjunctivitis, you might need to use antibiotic eye drops or ointments. To control the immunological reaction, antihistamine eye drops or oral medicines can be used to treat allergic conjunctivitis. After the irritant is eliminated and the eye is washed with clean water, irritant conjunctivitis frequently gets better.It is crucial to follow proper hygiene practices in order to stop conjunctivitis from spreading. This entails not sharing towels or pillowcases with someone who has conjunctivitis, routinely cleaning hands, and refraining from touching the eyes. If someone in your home has pink eye, you should wash their linens separately and thoroughly clean all surfaces. The chance of conjunctivitis spreading can be greatly decreased by following these steps.
