Almost everyone experiences itchy eyes from time to time.There are many causes of itchy eyes, and the problem often is accompanied by itchy eyelids— especially at the
base of the eyelashes— and red eyesores and swollen eyelids.
(Spoiler alert:rubbing your eyes won't help.)

Causes Of Itchy Eyes

Most of the time,itchy eyes are caused by some type of allergy.
An irritating substance (called an allergen)— such as pollen,dust and animal dander— causes the release of these compounds called histamines in the tissues around the eyes, which results in itching, redness and swelling.

Seasonal allergies cause what's known as allergic conjunctivitis.
It's most common in dry and dusty season and is caused by high pollen counts and exposure to outdoor allergens like grass and weeds.

Perennial allergies,on the other hand,are present all year long and are caused by things like mold and dust.

Because the causes for itchy eyes are so varied, if your symptoms are lasting, getting worse, or don't subside when allergy season stops, make an appointment with your eye doctor.
