Hayfever is one of the most common allergic reactions and affects over 400 million people worldwide and is on the increase. Pollen can set off an allergic reaction in the conjunctiva which becomes inflamed causing watery, red and itchy eyes.
One of the most common ways to treat hay fever is by taking anti-histamine tablets. Histamine is the main chemical released during an allergic reaction. By taking the tablets, you can combat itchy and watery eyes. Anti-histamine eye drops are also available if necessary.
