Why Do My Eyes Feel Dry in the Summer?

Do you find yourself with dry, uncomfortable eyes throughout the summer months? This is a normal phenomenon that comes down to a few different factors. In this article, we’ll explain why eyes tend to feel dry in the summer and what you can do to keep them hydrated. 

Reasons for Dry Eyes in the Summer

Sun Exposure

Increased sun exposure is one of the most common reasons for eye dryness in the summer. During June, July, and August, people tend to spend significantly more time in the sun, whether they’re on vacation, at the neighborhood pool, or taking their workouts outside. 

Without sunglasses that protect against the sun’s harsh UV rays, the tear film that keeps the eyes moisturized may evaporate rapidly. This can make the eyes feel drier than usual. 


Dehydration also tends to occur when people spend time outside in the sun. When the human body is dehydrated, it lacks sufficient water to maintain a healthy tear film, leading to dry eyes. 

Swimming in Pool Water or Seawater

The chlorine in swimming pools and salt in seawater can both dry out the eyes. Wearing goggles can prevent uncomfortable dryness if you’re planning to swim throughout the summer. 

Air Conditioning

When temperatures rise in the summer, people tend to crank up the air conditioning. AC use reduces the humidity in the air, which speeds up tear film evaporation and contributes to dry eyes. 

Summer Pollen Levels

Many people experience dryness from eye allergies in the summer months. Spring and summer are the prime months for high allergen counts, often leading to uncomfortable eye dryness for people with allergies. 

Wearing protective sunglasses or goggles while swimming, staying hydrated, using a humidifier, and seeking treatment for eye allergies can help you keep dry eye symptoms at bay. Reach out to The Eye Clinic of Florida to schedule an appointment for persistent dry eye and eye allergies.
