What Causes Dry Eye Symptoms in Summer? The 4 Major Triggers Impacting Grayslake Residents

Summer brings warmer temperatures, longer days, and more time outdoors in Grayslake. Unfortunately, the season can also bring burning, redness, watery eyes, and fluctuating vision. Understanding the most common summer dry eye triggers can help you protect your tear film and find the right treatment when symptoms persist.

1. Heat and Increased Tear Evaporation

Hot summer weather can cause tears to evaporate from the eye’s surface more quickly. This is especially noticeable during extended outdoor activities, such as walking, gardening, attending sporting events, or spending time near the lake.

Wind can accelerate evaporation even further. Without a stable tear film, the eyes may feel gritty, tired, or sensitive to light. Wearing wraparound sunglasses and taking breaks in shaded areas can reduce direct exposure.

2. Air Conditioning and Indoor Airflow

Air conditioning provides relief from the summer heat, but it also lowers indoor humidity. Dry indoor air can pull moisture away from the eyes, while ceiling fans, car vents, and desk fans may direct constant airflow toward the face.

Common signs that indoor conditions are affecting your eyes include:

•          Burning or stinging sensations

•          Redness and irritation

•          Watery eyes

•          Blurry or fluctuating vision

•          Contact lens discomfort

•          A gritty feeling that worsens throughout the day

Positioning vents away from your face, using a humidifier, and taking regular screen breaks may help reduce irritation. Persistent symptoms should be evaluated by an eye doctor in Grayslake.

3. Seasonal Allergies

Pollen, grass, dust, and other airborne allergens are more common during the warmer months. Allergies can cause itching, swelling, redness, and excessive tearing. Rubbing itchy eyes can further irritate the ocular surface and destabilize the tear film.

Allergy symptoms and dry eye symptoms often overlap, so using random over-the-counter drops may not address the underlying problem. A professional dry eye evaluation can determine whether your discomfort is related to allergies, tear evaporation, inflammation, meibomian gland dysfunction, or a combination of factors.

4. Sun, Swimming, and Outdoor Activities

UV exposure, chlorine, sunscreen, and prolonged outdoor activity can all contribute to summer eye irritation. Chlorinated pool water can disrupt the tear film, while sunscreen or sweat entering the eyes may cause temporary burning.

Dehydration can also make it harder for the body to maintain healthy tear production. Grayslake residents should wear UV-protective sunglasses, use swimming goggles, stay hydrated, and avoid wearing contact lenses while swimming unless specifically advised otherwise.

When At-Home Care Is Not Enough

Temporary dry eye symptoms may improve with environmental changes or doctor-recommended lubricating drops. However, recurring discomfort can indicate meibomian gland dysfunction, a condition in which the eyelid glands do not release enough healthy oil into the tears.

At Vision Care Grayslake, we offer OptiLight IPL, a noninvasive light-based treatment for dry eye associated with meibomian gland dysfunction. OptiLight uses precise pulses of light below the eyes to address inflammation, improve tear film stability, and support meibomian gland function. Our eye doctors can evaluate your symptoms and determine whether OptiLight IPL or another dry eye treatment is appropriate.
