Allergies: Causes, Systomps and Treatment | Bausch + Lomb


Allergies are your body’s natural response to certain medications or substances, usually resulting in itchiness, redness, and inflammation, among other symptoms. They may occur during particular seasons of the year, or year round, depending on what you’re allergic to. If you suffer from allergies, your eyes may be affected, too. They may be red, itchy, and watery and your eyes and eyelids may even be inflamed.

What Causes Allergies?

When your body comes into contact with an allergen or certain medications, your immune system naturally reacts, producing a chemical called a histamine. Histamine binds to tissue in the eyes, causing them to enlarge or dilate, which manifest as the symptoms of allergies.

Common allergens affecting the eyes include, but are not limited to, pollen, ragweed, grass, mould, weeds, dust, and pet dander.

Symptoms of Allergies

The most common symptoms of allergies include:

  • Redness
  • Excess tearing
  • Eye Itching
  • Sneezing
  • Sinus activity

Treatments for Allergies

In most cases, an eye care professional will recognize your symptoms as allergies, but more thorough examinations may include a slit lamp evaluation.

The best way to treat allergies is by avoiding allergens. For example, if you commonly experience allergic reactions during the springtime, you probably are reacting to pollens in the air, and should try to stay indoors as much as possible. Similarly, if you get allergies every time you’re in a house with pet hair, you’d be wise to avoid animals as best you can.

Allergy sufferers can benefit from daily replacement of contact lenses with a fresh, new lenses every day.
