you might have allergic reaction
or infective conjunctivitis
you need to consult eye doctor
donr touch your hand to eye and keep separate your all things .
it is infectious ,so there is chance of spreading to other people also
apply antiobiotic drops like oflox
three to four time a day
wash your eye with cold
avoid sunlight ,dusty and windy environment.
i hope i have answered your question.
