Why Dry Eye Symptoms Flare During Summer
Published:
If your eyes feel gritty, burning, watery, or unusually tired in the summer, warm weather may be part of the reason. Heat, sun exposure, dehydration, wind, and indoor cooling can all disrupt the tear film that keeps your eyes comfortable and your vision clear.
At Cascade Vision Center, we help patients understand what is driving their symptoms and recommend care that matches the cause, from simple home strategies to in-office options such as OptiLight IPL and radio frequency therapy.
Why Dry Eyes Often Feel Worse in Summer
Summer can increase tear evaporation and aggravate inflammation on the eye surface. When the tear film becomes unstable, symptoms such as dryness, redness, itching, burning, blurred vision, and light sensitivity can become more noticeable.
How Heat and Dehydration Affect Your Tear Film
High temperatures can speed tear evaporation, leaving the surface of the eye less protected. At the same time, seating and increased outdoor activity can contribute to dehydration, which may reduce the quantity and quality of your tears.
Even mild dehydration can make symptoms more noticeable. Drinking enough water throughout the day is a simple way to support healthy tear production, especially when you are spending more time outdoors.
Why UV Exposure Matters
Ultraviolet (UV) exposure is stronger during the summer months. Without proper protection, it can irritate the eye surface, contribute to inflammation, and worsen tear evaporation. Over time, cumulative UV exposure is also associated with conditions such as cataracts, pterygium, and macular degeneration.
Tip: wear high-quality sunglasses that block 100% of UVA and UVB rays every time you go outside. Wraparound styles offer extra protection from wind and dust. Visit our online store to find a pair that better matches your style.
How Air Conditioning and Fans Can Trigger Dryness
Air conditioning and fans can lower indoor humidity and move air directly across the eyes, which can make tears evaporate faster. Symptoms often become more noticeable during long periods in air-conditioned offices, car, or at home.
Simple adjustments can help:
- Avoid directing vents or fans straight at your face.
- Use a humidifier in your home or office to add moisture back into the air.
- Take regular breaks from screens and practice the 20-20-20 rule (every 20 minutes, look 20 feet away for 20 seconds) while blinking fully and frequently.
When to Seek Treatment for Persistent Dry Eye
If symptoms persist despite home care, recur frequently, or begin to interfere with reading, screen time, driving, or time outdoors, it may be time for a dry eye evaluation. Professional treatment can help identify the cause of your symptoms and improve both comfort and tear film stability.
At Cascade Vision Center, treatment recommendations are tailored to the type and severity of dry eye.
Our residency-trained optometrists use advanced diagnostics to determine whether your dry eye is primarily evaporative, aqueous-deficient, or mixed, then build a treatment plan specific to your needs.
