There are various causes of pink eye but the main cause is virus. Other causes of pink eye include bacteria, allergies, chemical exposure, certain diseases, contact lenses and fungi among others. The symptoms of the conjunctivitis include eye redness, itching eyes, increased tearing of the eye with clear or whitish liquid that is slightly thick, blurred vision, eye pain, sensitivity to light, a gritty feel in the eye, overnight formation of crusts on the eyelid resulting from yellow or grey tearing of the eye. Symptoms due to viral infection can be easily transferred from one eye to the other eye. The doctors diagnose the pink eye through eye examination or a swab of the lining is taken for analysis. The treatment of the pink eye depends on the cause. For chemical exposure or viral infection, the pink eye ends up disappearing on its own in around seven to ten days. For bacterial infection, the doctors usually prescribe a mild antibiotic eye drops or some ointments meant for killing the bacteria on the pink eye. The soothing of bacterial or viral infection can be achieved by application of warm compresses on the eye when closed. The treatment of pink eye caused by allergy is achieved by the allergen that caused it is avoided or removed. The allergic pink eye may also be soothed by cool compresses. Since this infection is contagious, it is spread by coming into contact with drainage from an infected eye. Good hygiene is the best way to prevent spread of pink eye by observing the following; washing your hands often, not sharing towels, eye cosmetics, handkerchiefs, handling, and cleaning contact lens equipments properly (WebMD). The complications of the pink eye are re-infection within the school or the household if the preventative measures are not followed. It is advisable that the children should go back to school after getting better or after begging the antibiotic treatment to prevent spreading the infection (WebMD).
The article did not accurately describe the science. Most likely, there is a need to understand the mechanism behind the normal eye that prevent it from this infection and why the infection likely affect the children. For instance, it could have explained that conjunctiva is always exposed to bacteria and irritants but the tears contain antibodies and enzymes that protect the eye by killing the bacteria.
The article increased my understanding about the pink eye as it clearly describes the conjunctivitis in a systematic and simpler way from its description, through causes and treatment to prevention.
The improvement of the article to explain more clearly on science is through provision of data that is analyzed in order to prove some points such as results showing that viral infection is the common cause of pink eye. It should also explain why the children are most affected by the infection. That is, the process that makes them susceptible to the infection.
In conclusion, pink eye or the conjunctivitis is the inflammation, swelling or infection of a membrane that lines the eyelids. The infection is contagious and it is common in children. The common cause of pink eye is through a virus while other causes include bacteria, allergy among others.
