Have allergy prone persons bathe/wash hair before bed to remove pollen from the hair & skin
Change out bed linens often (weekly) and pillowcases daily if able to do so
For allergy sensitive eyes; using baby shampoo (tear-free products) to "wash" eyelashes at least once per day to remove pollens/allergens. Use a tiny amount of tear-free shampoo on soft wash cloth with warm water & gently cleanse the lashes (with eyes closed of course) rinsing well.
