There are three primary types of pink eye, also called conjunctivitis, viral conjunctivitis, bacterial conjunctivitis and allergic conjunctivitis. Eyes can be watery and even bright lights can bother vision along with redness, eye pain and puffy eyelids. In conclusion, pink eye can be caused by viruses, bacteria and allergens. You can use some allergy medications to control the symptoms of allergic conjunctivitis. If you are indoors, you need to shut up the window, run your air-conditioner to filter the allergens and use the vacuum to clean the dust. Whereas you go our door, you may need to wear sunglasses. With timely rescue, most bacterial forms of conjunctivitis can be treated with antibiotic drops, but it will cause serious damage to the eye if left untreated. In addition, if viral infections are diagnosed, the drainage from the eye is contagious for about two days after antibiotic treatment, although it is still without medical treatment. It tends to resolve on its own. So it is not possible to be cured in 24 hours whatever form of conjunctivitis.
