During summer, hot winds, dust, pollen, chlorinated pool water, and intense ultraviolet (UV) radiation can harm eyes. Over time, these factors increase the risk of dry eyes, irritation, infections, and various eye conditions.

According to the U.S. Centers for Disease Control and Prevention (CDC), prolonged UV exposure can increase the risk of serious eye diseases without proper protection. Ophthalmology experts note that many summer eye problems stem from seemingly harmless habits.

Rubbing itchy eyes

Dust, pollen, and sweat are more prevalent in summer, making eyes prone to itching and discomfort. However, rubbing eyes can push irritants deeper, transfer bacteria from hands to the cornea, and damage eye tissues.

According to Timesofindia, instead of rubbing your eyes, apply a cold compress with a clean cloth or use artificial tears. Frequent hand washing and avoiding touching your face after being outdoors also help reduce the risk of irritation.

Inadequate hydration

Dehydration can reduce tear production, making eyes prone to dryness, grittiness, redness, or burning. Individuals should drink water regularly throughout the day, especially in hot weather or during extensive outdoor activities.

Direct fan or air conditioner airflow

Airflow from fans or air conditioners can accelerate tear evaporation, worsening dry eye conditions. Those with dry eyes should avoid direct airflow and consider using a humidifier to maintain indoor air moisture.

Wearing contact lenses for too long

Heat, wind, and dry air can increase eye discomfort when wearing contact lenses. Users may experience grittiness, burning, or irritation. To mitigate this, adhere to recommended wearing times, maintain proper hygiene, and switch to glasses if eyes show signs of dryness or redness.

Lack of UV eye protection

Many people wear sunglasses to reduce glare but pay little attention to UV protection. Similar to skin, eye tissues can also be damaged by ultraviolet radiation.

According to Verywellhealth, prolonged sun exposure increases the risk of cataracts, macular degeneration, and photokeratitis. Experts recommend using UV400 sunglasses or those blocking 99-100% of UVA and UVB rays when outdoors. Wearing a wide-brimmed hat and limiting outdoor time during peak sun hours also helps reduce the impact of UV rays on eyes.

Extended time in air-conditioned rooms

Spending too much time in air-conditioned rooms reduces air humidity, causing the tear film to evaporate faster. This results in dry, red, gritty, and tired eyes.

To minimize this impact, take regular eye breaks, blink frequently, and apply the 20-20-20 rule: every 20 minutes of screen time, look at an object about 6 meters away for 20 seconds to relax your eyes and maintain natural moisture.
