If you are prone to allergies, you may benefit from wearing sunglasses. At least that is what a Turkish study has found.
A test group of individuals who were suffering from seasonal allergy were given a nasal spray and Claritin (an anti-allergy medication). Half the test subjects were then asked to put on sunglasses. The test subjects who wore sunglasses for the entire day had to be administered less antihistamine. They also reported less allergic symptoms in the eyes.
The NHS in the UK says that the best way to prevent allergic reactions is to remove the allergen. But this is more easier said than done. Allergens like spores, dust mites and dust will be present even in the cleanest of houses and are difficult to remove.
The reason sunglasses can prevent allergies
Sunglasses act like a block against pollen, dust and UV rays – the most common culprits that lead to allergic symptoms in the eyes. They also deflect the wind, not allowing it to blow allergens into the eyes. Seasonal allergies or the allergies that kick in during spring or early summer are mostly caused by pollen. The average person blinks around 15,000 times everyday, but pollen can still manage to get in.
Did you know that eye allergens can also affect the nose? The nasolacrimal duct, otherwise known as the tear duct connects the eyes with the nasal cavity. So if you have ever been affected by an ocular allergy and a nasal allergy at the same time, know you know why.

Type of sunglasses used in the study
The researchers used large, wraparound sunglasses. These may not be stylish, but they are effective. To prevent allergies, the amount of air that circulates around the eyes has to be decreased. As the open space between your eyes and the eyeglasses increases, the risk of allergy also increases.
There are many types of sunglasses that cover the entire eye, for example sports sunglasses. These are trendy and no one will say that they are oversized. If you are a women, you can also wear bug eye sunglasses. These are fashionable versions of the large size sunglasses.
The good news is, all styles of sunglasses offer some protection, because pollen and dust are not the only allergens. UV rays can also cause allergies. UV blocking sunglasses can prevent symptoms that arise because of UV rays.
