Is it allergies?
Or is it dry eyes?

Eye allergies are responses to foreign substances like pollens, pet hair, dust, smoke, etc. Your eye allergies may be seasonal, perennial (i.e., all year long), or simply caused by contact (e.g., touching your eyes after petting a cat). 


Allergies and dry eye can present similar symptoms, and the difference between the two may be hard to tell. Symptoms may include: 

  • Burning eyes 

  • Itching 

  • Watery eyes 

  • Foreign body sensation 


The good news is that with proper care and instructions from your eye health professional, you may find relief of both dry eye and allergy symptoms.

Managing allergies

In general, avoiding allergens which may trigger the initial response is a good strategy to prevent allergies! However, sometimes it may prove to be easier said than done. Some examples to reduce your allergy exposure and contact include staying indoors when the pollen level is high, wearing sunglasses, and washing your face after exposure to allergens.


Your doctor may recommend some lubricating eye drops and lid hygiene treatments as a first line of defence. They may also recommend oral medications (antihistamines/mast cell stabilizers) and oral decongestants, which may prove to be effective in allergy relief. But these may lead to unwanted dryness of your eyes.

Nature's ingenuity to the rescue

Leveraging the intuition of nature, you can protect your eyes against allergens, reduce dehydration and irritation, and keep your tears from evaporating excessively.

Ectoine and Sodium Hyaluronate are both natural substances that can help you find relief from both allergies and dry eyes

Ectoine: nature's answer to extreme environments

There are places on our earth that are so extreme, that life just cannot seem to exist. Surprisingly, some microorganisms, called extremophiles, found their means of survival.

Among many, extremophiles "shield" themselves by producing extremolytes like Ectoine.

The "shield"

Ectoine has a strong affinity for water. Ectoine and water will tightly grab onto each other and form a physiologic barrier.


This ectoine-water “shield” protects cell membranes from contact with allergenic substances and against inflammatory responses to environmental stress (e.g., dehydration by hyperosmolar tears, UV radiation, airborne allergens)

When you thought there couldn't be more benefits

Additionally, Ectoine helps protect against the excessive evaporation of tears. Ectoine has a stabilizing effect on the lipid phase (oily layer) of the tear film.


The lipid layer is the outermost layer of our tears. Its function is to reduce the tears from evaporating. Ectoine helps increase its elasticity, causing it to spread evenly over the eye surface and protects against the excessive evaporation of tears.
