Thanks for your query at HCM! Adenovirus, a DNA virus which causes respiratory infections, pharyngoconjunctival fever, keratoconjunctivitis, diarrhoea, etc depending upon serotypes of virus. It spread occurs via the respiratory route and contact with ocular secretions during the acute illness among family members. Most infections are mild and require no therapy or only symptomatic treatment. You can use topical antiobitic for eyes. If your problem still persists with disturbance in vision then you must visit an ophthalmologist. Take care.
