Sore Eyes

Sore EyesSore eyes – rather than a blocked or runny nose - are for some people with allergies the most common symptoms. Red, sore, watery eyes are especially common in hay fever, with the conjunctiva becoming inflamed and the tissue around the eyes swollen. Sore eyes can be prevented by avoiding the offending allergens. However, medication such as an antihistamine can also be used to reduce allergic eye symptoms.

What are the symptoms of sore eyes?

top of page ^

Clinically known as periorbital puffiness, puffy or sore eyes is a common symptom with many possible causes, including ocular (eye) allergy. Puffy eyes mean a swelling in the tissues around the orbit of the eyes. Sore eyes are not the same as 'bags under the eyes'. The symptoms of allergic eye disease include:

  • Sore eyes
  • Puffiness
  • Redness of the eyes
  • Itching
  • Discharge
  • Watery eyes
  • Sensitivity to light (photophobia)

What causes sore eyes?

top of page ^

Allergies are one of the most common cause of sore eyes. Exposure of the eyes to an allergen like pollen, pet dander or mould causes an over-reaction in the immune system. One major component of this reaction is the release of a chemical called histamine from mast cells, a type of immune cell. Histamine has various effects, one of which is to make tiny blood vessels around the eye swell and become leaky, thereby releasing fluid into the surrounding tissue and causing swelling.

Three of the main types of ocular allergy all have similar symptoms and all come under the heading of conjunctivitis, sometimes known as 'pink eye'. The conjunctiva are the outermost layers of tissue covering the eye itself and the inside of the eyelids. The allergic response described above also causes inflammation in the conjunctiva, as well as puffiness in the tissue around the eye. The three types of allergic (sometimes also known as atopic) conjunctivitis are:

  • Seasonal allergic conjunctivitis: This is really a form of hay fever, in which ocular, rather than nasal, symptoms predominate. It is the most common form of allergic conjunctivitis, occurring mainly in spring and summer and caused by exposure to pollen. An allergy to mould may produce seasonal allergic conjunctivitis in the autumn months when there are more mould spores around. Both eyes are usually affected.
  • Perennial allergic conjunctivitis: Less common than the seasonal condition, in the perennial form of allergic conjunctivitis, symptoms like puffy eyes occur all year round. The person often also suffers from eczema. The cause is an allergen that is present all the time such as; house dust mite, followed by animal (cat or dog) dander. Both eyes are usually affected.
  • Acute allergic conjunctivitis: This condition normally affects just one eye. Symptoms come on very rapidly and are often caused by exposure to ragwort pollen. Symptoms can be quite dramatic, with a lot of swelling. Symptoms soon clear up once the trigger is removed.


There are non-allergic causes of sore eyes, these include:

  • Lack of sleep
  • Conditions causing fluid retention, such as pregnancy and excess salt in the diet
  • Crying, when the salt in tears leads to fluid retention
  • Dysfunction of the tear glands

What kind of allergens cause eye problems like sore eyes?

Airborne allergens like pollen, mould or dust often cause eye problems. Pollen grains are readily deposited on the surface of the conjunctiva because of their size and shape. However, some people are allergic to other substances, such as the ingredients in eye make-up or contact lens solutions.

What might cause ocular contact dermatitis?

top of page ^

There are many possible causes, including exposure to:

  • Eye medications such as atropine or neomycin
  • Metal components of spectacles
  • Eye cosmetics
  • Perfume
  • Adhesive fumes

How can sore eyes be treated?

top of page ^

Limit your exposure to the symptom causing allergens as much as possible through practicing allergen avoidance. In regard to medical treatments, there are a couple of different options. Oral tablet form antihistamines are the standard treatment for sore eyes caused by allergy. The 'second generation' non-sedating antihistamines, like loratadine (Claritin) or acrivastine (Benadryl Allergy Relief or Benadryl Plus Capsules).

There are also a number of antihistamine eye drop formulations for allergic conjunctivitis such as:

  • Ketotifen (Zaditen)
  • Azelastine (Optilast)
  • Antazoline and xylometazoline (Otrivine-Antistin) which contains two different medications. The antazoline is an antihistamine, while the xylometazoline is a vasoconstrictor, which reduces swelling round the eyes by making local blood vessels contract.


If antihistamines are not effective other treatments include:

  • Topical sodium cromoglicate (Pollenase Allergy, Opticrom, Catacrom): This works by reducing the amount of histamine produced (while the antihistamine blocks its action).
  • Topical corticosteroids: Topical corticosteroids may produce thinning of the cornea or glaucoma.
  • Oral corticosteroids: should be reserved for ocular allergy with very severe and persistent symptoms and should only be prescribed under the supervision of an ophthalmologist.


With eye drops, you need to be careful to avoid infection by not allowing the dropper to touch your eye and by never using 'out of date' eye drops. If you have any questions, please ask your pharmacist.

How can I prevent sore eyes?

top of page ^

Allergen avoidance is the key to preventing sore eyes. If pollen is the problem, try the following:

  • Wear wraparound sunglasses
  • Keep car windows closed when driving
  • Wash pollen out of your hair when returning home
  • Keep an eye on pollen counts and plan your day's activities accordingly


With the perennial form of allergic conjunctivitis, try to keep down airborne household allergens by:
