Eye redness: due to excessive use of vasoconstrictor eye drops can happen, what is called rebound vasodilation (conjunctivitis medicamentosa) , so better use in moderation, not to exceed 3 days at a time, and treat the cause, your ophthalmologist can help. Cold water isn't expected to cause eye redness, best wishes
