Understanding Smoke from Wildfires and Its Impact on Your Eyes

Each year, wildfires affect communities across California, sending thick smoke into the air that can linger for days or even weeks. While many people focus on how wildfire smoke affects the lungs and breathing, it’s equally important to understand how it impacts the eyes. The small particles, chemicals, and gases carried in smoke can cause irritation, discomfort, and even long-term eye issues if exposure continues.

At Li & Liao Optometry, we care about the health and comfort of your eyes, especially during challenging wildfire seasons. Here’s what you need to know about smoke exposure and how to protect your vision.

Wildfire smoke contains a mix of fine particles, ash, and toxic gases that easily irritate the eyes. Even short-term exposure can cause:

• Redness and irritation
• Excessive tearing or watery eyes
• A gritty, burning, or stinging sensation
• Sensitivity to light
• Blurred vision

For those who already deal with dry eye syndrome or allergies, smoke exposure can make symptoms worse. Prolonged exposure to smoke may also increase the risk of infection or more serious eye conditions, especially if the surface of the eye becomes inflamed or damaged.

Certain groups are more sensitive to wildfire smoke, including:

• Children and older adults
• People with chronic dry eye or allergies
• Contact lens wearers
• Those with preexisting eye conditions like blepharitis or conjunctivitis

 

1. Stay Indoors When Possible

When smoke levels are high, limit outdoor activities. Keeping windows and doors closed reduces exposure to airborne irritants.

2. Improve Indoor Air Quality

Run air purifiers with HEPA filters to remove fine particles from indoor air. If you use central air conditioning, make sure the filter is clean and set to recirculate indoor air rather than bringing in smoke-filled outdoor air.

3. Wear Protective Eyewear and Masks Outdoors

If you need to go outside, wear wraparound sunglasses to block airborne particles. A well-fitted N95 mask also helps reduce smoke inhalation and keeps irritants from reaching your eyes.

4. Use Lubricating Eye Drops

Artificial tears can help rinse away particles and keep your eyes moist. Use preservative-free drops to avoid added irritation if you’re applying them frequently.

5. Avoid Rubbing Your Eyes

While it’s tempting to rub irritated eyes, doing so can worsen redness or even cause scratches on the cornea. Instead, rinse with sterile saline solution or artificial tears.

6. Take Out Contact Lenses if Irritated

Smoke particles can cling to contacts, making symptoms worse. If you notice discomfort, remove your lenses and wear glasses instead until conditions improve.

7. Schedule an Eye Exam if Symptoms Persist

If irritation, redness, or blurry vision continues after smoke exposure, it may be time to see an optometrist. At Li & Liao Optometry, we can examine your eyes, recommend treatment, and ensure there’s no lasting damage.

Wildfire smoke has become a regular challenge in California, but that doesn’t mean you have to suffer through eye discomfort. With the right preventive steps and professional care when needed, you can keep your eyes healthy and comfortable throughout fire season.
