What Is Allergy?


An allergic reaction can be a nuisance, but it’s one of the immune system’s many responses to invaders that enter the body.

Allergies are quite a unique immune response, though, because the immune system reacts to substances that are not necessarily harmful. These are called allergens, and they are often objects from your surroundings.

Pollen, dust, and pet dander are common allergens in the environment. Many are sensitive to various types of food, too. They’re not harmful substances, but you just happen to be allergic to them.

Once allergens enter the body, the immune system see them as a threat and produces antibodies to attack them. This immune response causes allergic reactions like runny nose, sneezing, coughing, rashes or hives, and watery eyes.


What Are Seasonal Allergies?


Do you get allergies more often during certain times of the year? Then, that could be due to seasonal allergies, also known as hay fever or allergic rhinitis.

Seasonal allergies are quite common, and they affect over 25% of adults in the United States, according to a 2023 report from the Centers for Disease Control and Prevention (CDC).


What Makes Allergies ‘Seasonal’?


Spring, summer, and fall are the best seasons to enjoy nature. Unfortunately, these times of the year are not always blissful for people with seasonal allergies.

Plants release pollen during these seasons, which is mixed into the air. When inhaled, pollen can easily get trapped in the mucus membrane, and if you have a seasonal allergy, this could trigger a reaction.

Common allergens according to the season:

  • Tree pollen: Spring, between February and April
  • Grass pollen: Summer, between June and July
  • Ragweed: Fall, from August and can last through mid-September

  2. Atopic keratoconjunctivitis commonly affects older people who have experienced allergic dermatitis and can cause corneal damage when not treated.
  3. Contact allergic conjunctivitis occurs when protein builds up from tears and contact lenses, which causes eye irritation and vision problems.
  4. Giant papillary conjunctivitis is a severe form of contact allergic conjunctivitis when papules or fluid sacs develop on the inner eyelid.


Dry Eyes vs Allergies


Most symptoms of eye allergy are similar to dry eyes, but these are different conditions that affect your vision.

While eye allergies are triggered by allergens, dry eyes are often caused by the lack of moisture on the eye’s surface.

Dry eyes can be caused by environmental factors like dry air, sunlight, smoke, and strong winds. However, they can also be caused by aging, hormonal changes, eye strain, and some medications.

You may need medication and other remedies to relieve the symptoms when allergies affect vision. However, eye protection and eye rest can offer relief in most cases for dry eyes.


Home Remedies and Treatment for Eye Allergies


Seasonal allergies and types of eye allergies with milder symptoms can be easy to manage.

Eye drops formulated with antihistamines, decongestants, or corticosteroids are common treatment options for eye allergies. These can help reduce itching, swelling, redness, and inflammation to improve your vision during allergy season.

However, always consult your healthcare provider to determine the best allergy eye drop for you.

You can also opt for simple home remedies to relieve the common symptoms of eye allergies. You can apply a cold compress over your eyes for a few minutes to reduce the symptoms.

During allergy season, using an air purifier may also help reduce the allergens in your surroundings.


How to Protect Your Eyes from Allergies


If you are prone to allergic reactions, whether seasonal or year-round, you should be proactive about protecting your eyes from environmental irritants to lessen your reactions.

Here are some ways you can do to protect your vision:

  • Monitor pollen forecasts. If there are high pollen counts, stay indoors as much as possible.
  • Wear eye protectors like sunglasses to lessen contact with pollen and other allergens if staying indoors is not possible.
  • Keep your windows closed during peak allergy seasons, or keep an air purifier in your room or workplace.
  • Make sure your hands are clean before touching your face and eyes to reduce chances of contact with allergens.
