Allergic conjunctivitis - what should I look out for?
It is sometimes difficult for a doctor to tell the difference between allergic and infective conjunctivitis. Particularly in the hay fever season when red, watery eyes are common. Also, some other eye conditions can cause a red eye, and may be mistaken at first for conjunctivitis.
Therefore, see a doctor if any of the following occur.
- Symptoms do not settle within a few days of treatment.
- Symptoms change (for example, light starts to hurt your eyes).
- Pain becomes worse (mild soreness rather than pain is usual with conjunctivitis).
- Spots or blisters develop on the skin next to the eye.
- Your vision becomes affected.
