Recently, my eyes are particularly itchy. What's going on?

The eyes are particularly itchy, mostly caused by allergies, which can be allergic conjunctivitis or acute contact dermatitis. It can be caused by a wide variety of allergens. Allergic conjunctivitis is caused by hypersensitivity of eye tissues to allergens. For example, pollen, corneal contact lenses, etc. can cause immediate allergic conjunctivitis; drugs generally cause delayed allergic conjunctivitis. It is manifested as itching of the eyes, eyelid edema, conjunctival hyperemia and edema. Plant pollen can cause seasonal allergic conjunctivitis, normal onset in spring. House dust, animal fur, etc., can cause perennial allergic conjunctivitis. Please go to the hospital for specific treatment, find allergens, symptomatic treatment.
