Eye irritation, redness, and watery eyes after wearing contact lenses are often caused by dryness, allergic reactions, or improper lens hygiene. Contact lenses can reduce oxygen supply to the eyes or trap irritants, leading to these symptoms.

• Common reasons include dry eyes due to reduced tear film, sensitivity to lens material or cleaning solutions, or wearing lenses longer than recommended.
• Using lubricating eye drops like artificial tears (e.g., those containing carboxymethylcellulose) can help relieve dryness, but you should remove lenses before applying drops and wait at least 15 minutes before reinserting them.
• Persistent or worsening symptoms should prompt a visit to an ophthalmologist (eye specialist) to rule out infections or other complications.
