Dry Eyes in the Summer Heat? Causes, Remedies, and Prevention Tips
Toronto summers are filled with sunny days, backyard barbecues, and fun family outings—but they can also bring an unexpected nuisance: dry, irritated eyes.
While dry eye syndrome is often associated with winter, the summer heat, increased outdoor activity, and constant air conditioning can leave your eyes feeling scratchy, tired, or even burning.
If you or your children are experiencing these symptoms, you're not alone. Understanding the causes and knowing how to treat and prevent summer dry eye can help keep your family’s vision clear and comfortable.
Why Summer Triggers Dry Eyes
Several seasonal factors contribute to dry eye symptoms, especially in urban environments like Toronto:
Heat and sun exposure: High temperatures can increase tear evaporation, especially on windy days or when you’re spending hours outdoors.
Air conditioning: Whether you're indoors at home, shopping malls, or in the car, A/C reduces humidity, drying out the eyes.
Outdoor allergens and pollution: Summer pollen, smog, and dust—common in city air—can inflame the eyes and reduce natural tear production.
Dehydration: Being active in the heat without proper hydration can affect tear consistency and eye comfort.
Children, seniors, and contact lens wearers are particularly susceptible.
Simple Remedies and Prevention Tips
Thankfully, managing dry eye in summer is easier with a few proactive steps:
Use preservative-free artificial tears: Lubricating eye drops can restore moisture. Look for preservative-free options to avoid irritation, especially for frequent use or kids.
Stay hydrated: Encourage your family to drink plenty of water, especially during outdoor activities or sports camps.
Wear sunglasses outdoors: Wraparound UV-blocking sunglasses reduce sun exposure and protect from wind and dust.
Limit A/C exposure: At home, use a humidifier to balance dry indoor air. In the car, direct vents away from your face.
Practice the 20-20-20 rule: For screen-heavy days, remind kids to take a 20-second break every 20 minutes by looking 20 feet away to reduce eye strain.
When to See a Doctor
If over-the-counter remedies aren’t helping, or symptoms persist—such as excessive tearing, redness, or blurry vision—it’s time to consult an optometrist. Chronic dry eye may require customized treatment or prescription drops. If you think you need to speak with someone, you can book an appointment with us here.
