Allergic Conjunctivitis
Affects Your Eyes, Though
Not For Long With Treatment

Allergic conjunctivitis is one of the types of conjunctivitis.

Conjunctivitis is a condition that affects your eyes. It makes your eyes red, itchy and watery.

You may also get a sticky film on your eyelashes.

In the morning you may find that this sticky film means that you're unable to open the eye that is affected.

There are several different types of conjunctivitis.

Allergic conjunctivitis is the type that is classed as an atopic condition.


It is caused by an allergic reaction to a substance.

The main culprits are

If you are allergic to pollen, which is at certain times of the year, it is called Seasonal Allergic Conjunctivitis. Your symptoms would affect you during the hay fever season.

Pollen comes from

  • Grasses. You would normally be affected between May and August
  • Trees. Different trees would affect you at different times. The most common allergen is birch, which is worse in April
  • Weeds. You would normally be affected around September/October

If you allergic to house dust mites, which can affect you all year, it is called Perennial Allergic Conjunctivitis.

It is very useful if you know what allergen causes your conjunctivitis. You would be able to limit contact with it, so stopping the symptoms before they start.

Symptoms Of Allergic Conjunctivitis

The main symptoms to look out for include

  • both of your eyes will likely be affected
  • the whites of your eyes will become red (hence why some people call it 'red eye')
  • your eyes will be watery, and there may be a sticky glue on your eyelashes
  • your symptoms will generally be worse in the morning if you are allergic to pollen. Look out for a runny or blocked nose, and sneezing

It is important not to rub your eyes. This can make the inflammation worse.

Also if you wear contact lenses it is a good idea not to wear them while you have any of the symptoms.

Once you have been diagnosed you can start treatment.


There are a few different treatments that you can use to improve the condition.

  • If your symptoms are mild you may not need any other treatment. Just avoid the allergen, and avoid rubbing your eyes
  • Antihistamines. These help with treating an allergy. They may reduce eye symptoms. But are more useful if pollen is the allergen. As they help to improve the runny or blocked nose, and the sneezing
  • Eye drops. These will reduce the allergic reaction. There are 2 types
    • Antihistamine eye drops. Provide quick relief. You can get them on prescription, though some are available to buy over the counter
    • Mast Cell Stabilisers. Slower to work. They provide relief over a longer period of time. So until they work fully you maybe advised to take antihistamine tablets too
  • Oral Steroids. You maybe given a short course, no longer than a week. Though they are only prescribed if your symptoms are severe. They are not recommended for long term use

This type of conjunctivitis doesn’t generally cause any major problems. It normally clears up within a few days.

If it is not improving as it should, visit your doctor.

Also visit your doctor if

  • Your symptoms change
  • Your eyes get very red, especially if it affects just one eye
  • Your eyes feel painful. They may feel a little sore with conjunctivitis, but not painful
  • You are sensitive to light
  • Spots appear at the side of your eyes

They all indicate that you may have a different condition. So visit your doctor so you can get the right treatment for the condition you have.

If you are not sure if your conjunctivitis is caused by an allergy, or if it is, by what allergy, having an allergy test maybe the answer.

Luckily allergic conjunctivitis will not normally affect your life in an adverse way. Especially in the long term.

If you limit contact will allergens, and start treatment as soon as you see any symptoms, managing it will be a piece of cake.
