However, in some individuals iritis recurs at the same time each year, and an allergic cause is suspected. Preventing problems associated with iritis requires first, recognizing light sensitivity and redness of the eye require immediate examination by an eye specialist. Subsequent attacks of iritis are easily recognizable early on based on the soreness, redness, and change in vision that occur. Instituting treatment quickly will help prevent many of the long term complications. Certain medical conditions, including a disease called sarcoidosis and fungal infections, must be ruled out.
Good hygiene is a good place to start.
Clean hands, avoiding rubbing of the eyes, keeping the eyelids and lashes cleansed and scrubbed through regular hygiene is normally sufficient. At all costs avoid touching near an eye that is red and or has a discharge. You will almost certainly spread it to the other eye, as well as others around you. Colds are highly contagious, a common cause of pink eye, and spread to the eye in much the same manner as they do the upper respiratory tract - through close contact. Colds represent viral eye infections, some of which are extremely contagious.
