Protecting your eyes from bushfire smoke

The impact of bushfire smoke on the eyes 

While there is a wealth of information on the impact of smoke on the respiratory system, the ocular surface has received comparatively little attention. However, eye symptoms are among the most experienced during bushfire crises. 

“Smoke contains fine and coarse particles along with noxious gases that can wreak havoc on the delicate mechanics of the ocular surface. These particles can embed into the cornea, causing constant irritation, or they can deposit in the tear film, leading to allergy-like reactions that affect vision and disrupt daily tasks,” said Ms Sukanya Jaiswal, optometrist and PhD candidate at School of Optometry and Vision Science at University of New South Wales (UNSW). 

Education and preparation are key 

Suki and her team’s research through UNSW endeavours to provide early insights into preventative care measures that can protect our eyes during future bushfire crises. 

With a hotter than average summer predicted and the potential threat of another rampant bushfire season ahead of us, it's a crucial time for Aussies to be informed about bushfire smoke exposure and how to mitigate its impacts on the ocular surface.  

Persons with pre-existing eye surface disease such as dry eye disease or with pre-existing respiratory disease are warned to be especially alert and take precautions, as they have greater risk of eye problems with exposure to bushfire smoke. 

By staying vigilant about eye health during bushfire events, we can take steps to protect our vision and well-being in the face of these natural disasters.
