It's that time of year again: tree and grass pollen season is in full swing, and for many of us that means dealing with allergies. One of the most common complaints at this time of year is watery eyes. But why does this happen and what can we do to get relief? Let's look at the causes of watery eyes and explore some solutions.

The culprit: allergens

When your body comes into contact with an allergen - such as pollen during the tree and grass pollen season - it perceives these harmless substances as a threat. In response, your immune system goes into overdrive and produces antibodies. These antibodies trigger the release of histamine, a chemical that causes the symptoms of an allergic reaction, including watery eyes.

Why your eyes react

The histamine released during an allergic reaction increases the permeability of the blood vessels in your eyes, causing fluid to leak. This is your body's attempt to flush out the perceived threat. Histamine can also cause irritation and inflammation, leading to increased tear production as your eyes try to soothe themselves.

Finding relief

Allergy medicine

There are several allergy medications that can help manage your symptoms. Allergy pills and drops, which often contain antihistamines, can be particularly effective in reducing watery eyes by blocking the action of histamine.

Allergy nasal spray

Although it may seem unrelated, using an allergy nasal spray can also help with eye symptoms. These sprays can reduce the nasal inflammation and congestion often associated with allergies, which in turn can relieve the pressure and irritation that contribute to watery eyes.

Saline spray

A saline nasal spray or saline sprays can help remove allergens from your nasal passages, reducing your overall exposure to them. This may indirectly help to relieve your eye symptoms by tackling the root cause of the allergy.

Prescription options

For those with severe symptoms, a prescription nose spray or other prescribed allergy treatment options might be necessary. These can include stronger medications that target inflammation and allergic reactions more effectively. Always consult with a healthcare provider to find the most appropriate treatment for your needs.

Protective measures

During high pollen counts, wearing sunglasses when outdoors can help protect your eyes from allergens. Additionally, try to keep windows closed during peak pollen times to minimise indoor exposure.

In conclusion

Watery eyes during allergy season are a direct result of your body's reaction to allergens such as pollen. Understanding this process can help you better navigate your allergy relief options, from over-the-counter allergy medications to prescription nasal sprays and practical measures like wearing sunglasses. Remember, you don't have to suffer in silence; there are many solutions and allergy treatments available to help you enjoy the seasons with clear, comfortable eyes.
