Is the vision affected?
Is there any discharge present?
Colds are due to virus which may involve eyes as well. It is most likely a viral conjunctivitis and should resolve within a week's time. Sometimes, cornea gets involved in viral conjunctivitis and steroid drops may be required. You can see a doctor to confirm the diagnosis. Thanks.
Follow-up questions, if any, are welcome.
