Many people across the UK are already suffering with hay fever season symptoms, with hay fever season now starting as early as February and March*. 

March is the peak pollen release month for hazel, yew, alder, elm and willow trees, while birch, plane, oak and ash trees release pollen from March. 

Grass pollen season typically stretches between May and early September and oilseed rape typically peaks in May and June. 

Daniel Hardiman-McCartney MBE, clinical adviser at The College of Optometrists, says: “Pollen grains can set off an allergic reaction in the  eyes, which causes watery, red and itchy eyes. This may make your eyes and eyelids swell, and you may also experience a gritty feeling in your eyes.  

“Speak to your local optometrist for advice about the best way to manage and treat itchy or swollen eyes caused by hay fever. Optometrists are based on the high street and are your first port if call for eye health care and advice.”
