Hay fever is a common allergic reaction to pollen, and it usually gets much worse as spring’s warm weather arrives, with plants bursting into bloom and grasses ripening.
Hay fever can cause a range of symptoms, including itchy, watery eyes.
How hay fever affects the eyes
When pollen comes into contact with your eyes, it can cause an allergic reaction. This reaction causes your eyes to produce more tears, which makes them watery. Your eyes could also react by becoming itchy, red, swollen, and irritated.
Hay fever can sometimes cause more serious eye problems:
Allergic conjunctivitis: your eyes become red, itchy and watery, and hence bright sunlight may hurt your eyes
Vernal conjunctivitis: chronic allergic changes that lead to under the lid changes and more serious eye irritation
Blepharitis: causes your eyelids to become red, itchy and flakey.
