During which seasons do allergies most affect the eyes?

Seasonal eye allergies most affect the eyes in spring and summer, as this is the period of pollination. Seasonal allergic conjunctivitis, which is primarily associated to pollen, is the most prevalent form of eye allergy and its main symptom is itching, as well as redness, water eyes, swollen eyelids and a feeling of burning or of a foreign body. 

Another seasonal eye allergy that must be considered is vernal keratoconjunctivitis, which is typical in children and that also often appears in spring and summer. In this case, the symptoms are more serious because, apart from itching, vision can be threatened by the injuries caused to the cornea.
