What could cause unilateral eye redness, increased moisture, and difficulty fully opening the eye during a common cold, and is an evaluation by an ophthalmologist recommended if these symptoms persist despite general medical treatment?
A viral infection can easily spread to the eye, causing viral conjunctivitis. This can lead to redness, extra watering, and mild swelling that makes it hard to open your eye fully. While this usually resolves on its own with rest and warm compresses, it is important to monitor it closely. If these symptoms persist despite general cold treatment, or if you develop severe pain, vision changes, or light sensitivity, consulting an ophthalmologist is highly recommended.
