Vision is a fundamental human need. If you have trouble seeing clearly, you have visual impairment. In addition to the more common symptoms of redness, increased tear production, inflammation, stinging, and pain, conjunctivitis, or "pink eye," can produce a number of other unpleasant changes in the eyes. Viruses pose a risk to the health of the eye. The virus spreads through droplets in the air and through close contact with infected people. The pink eye epidemic began in Karachi but has now expanded to other major towns in Pakistan such as Lahore. In Punjab, 86,133 incidences of pink eye were reported. Some of the symptoms of Pink Eye Flu include redness, itching, tears, and photophobia (sensitive to light).The process of releasing fluid from the eye, usually at night.
