Year-round or seasonal allergic conjunctivitis
When environmental allergies cause dry eyes, individuals may experience certain eye symptoms, e.g.

Vernal keratoconjunctivitis and atopic keratoconjunctivitis are more serious forms of eye allergy. Men with neurodermatitis or asthma are particularly affected.

Giant papilla conjunctivitis is a more severe form of allergic contact conjunctivitis.
The conjunctivitis symptoms listed above are the large papillae, but one can also experience:

A person can take home steps to manage and treat dry eye. This includes environmental controls and combinations of over-the-counter and prescription drugs.
ACAAI recommends reducing allergens in the environment:
- Wear glasses instead of contact lenses
- Wash hands after handling animals
- Use a dehumidifier to control mold in your home
- Stay indoors as much as possible during times of high pollen counts and closed windows
- Wear sunglasses or goggles outdoors to prevent pollen from entering your eyes.

When you talk to your doctor
Because there are many causes of dry eye, you should call your doctor if dry eye persists or if your symptoms don’t improve. A doctor can identify and diagnose other causes of dryness.
Doctors often ask about symptoms and examine the affected eye. According to the American Optometric Association (AOA), your doctor will check for:
- What the eyes look like on the outside, including the shape of the eyelids and how a person closes their eyes
- What the eyelids and cornea look like under bright light and magnification
- The amount of tears a person produces
- Nature of human tears
If your doctor suspects an allergy, he may recommend allergy testing.
An irritant such as pollen, smoke or pet dander, an underlying medical condition, or a drug reaction can cause dry eyes.
Dry eye usually causes redness, pain, and itching. Taking over-the-counter medications and taking steps to avoid exposure to allergens can help.
If you can’t control dry eye, you should see your doctor.
