BEST 5 Tips For Red Itchy Eyes From Eye Allergies

The most common cause of itchy eyes is an allergy. Itchy eyes can be triggered by exposure to pollen, animal fur, mould, dust mites, make-up or eye drops. The body reacts to the trigger by releasing histamine, causing the blood vessels in the eye to dilate and irritating the nerve endings so the eyes water. When the eyes get red because of an allergy, it is known as allergic conjunctivitis .

Allergic conjunctivitis is more common at certain times of the year, although you can still have it all year round. It also causes a runny nose, scratchy throat and sneezing.

Other types of allergy can give you itchy eyes. For example, a condition called atopic keratoconjunctivitis produces an inflammation of the surface of the eye because of an allergy to a specific substance. Another condition, vernal keratoconjunctivitis , produces inflammation in the membrane on the surface of the eye. This usually affects young boys.

If you have eczema, a form of dermatitis, around your eyes this too can cause itching.

Other causes of itchy eyes include:

  • dry eye syndrome when you do not produce enough of the right kind of tears to keep the surface of your eye moist and comfortable

  • Many cosmetics , will cause a contact allergy of the eyelids, which may occur in only one eye

  • Usually there is an initial improvement of the condition after prescribed eye drops are used and then a continuing deterioration, only improved by ceasing the eye drops.
  • Bathing the eyes with cooled boiled water will give comfort as the condition improves.
  • A doctor will usually use patch testing to confirm the diagnosis and inquire about whether any non-prescribed or herbal drops have been used.

How Are Eye Allergies Diagnosed

Then theyll perform a skin prick test to determine the underlying cause of your symptoms. A skin prick test involves pricking the skin and inserting small amounts of suspected allergens to see if theres an adverse reaction.

A red, swollen bump will indicate an allergic reaction. This helps the allergist identify which allergens youre most sensitive to, allowing them to determine the best course of treatment.

The best way to treat an eye allergy is to avoid the allergen thats causing it. However, this isnt always possible, especially if you have seasonal allergies.

How To Treat Dry Eyes From Allergies

Eye Allergy, Causes, Signs and Symptoms, Diagnosis and Treatment.

There are many different treatments for dry eye ranging from over-the-counter artificial tears to prescription medications to lid procedures. Dr. Schellenberg says finding the right treatment depends on the root of the problem.

The best way to differentiate dry eye syndrome from allergies is to first have an eye exam, as they can be difficult to manage without a treatment plan from an eye doctor.

Ocular allergies are often treated with antihistamine drops. There are several over-the-counter and some stronger prescription antihistamine drops available, she says. Additionally, steroid drops may be needed if ocular allergies are severe.

Since antihistamine drops can decrease tear production, your eye doctor may recommend using preservative-free artificial tears in conjunction with allergy drops to keep your eyes lubricating and from drying out.

Before trying medications, there are several simple things you can try to see if your symptoms improve. Avoiding allergens altogether can limit the histamine production, thus decreasing the dry, itchy feeling in your eyes.

This may sound easier said than done, but avoid going outdoors when pollen counts are higher early at dawn and dusk. Keeping windows closed during the summer can keep allergens from getting in your house. Clean your house regularly to remove dust and pet dander that collects on surfaces.
