It will not. Red eye is an epidemic haemorrhagic conjunctivitis, a contagious eye disease caused by a virus, which can improve on its own with symptomatic treatment. Inflammatory or neoplastic diseases of the eyelids are not contagious and cannot be passed on to family members. When encountering red eye, patients should pay attention to personal hygiene and isolation, wash their hands regularly, use separate towels and steam sterilise them, disinfect living utensils etc separately, avoid public places such as bathhouses and swimming pools, do not shake hands with others, and seek prompt medical attention.
