Dealing with dry eyes can be annoying and uncomfortable. While most people are aware of common causes, there are some surprising habits that can make the condition worse. Understanding these unexpected triggers is key to finding relief. Let’s explore some unexpected habits that could be contributing to your dry eyes.
1. Staring at Screens Without a Break
It’s easy to lose track of time when you’re engrossed in your favorite show or working on your computer. However, prolonged screen time without breaks can significantly reduce your blink rate, leading to dry eyes. Remember the twenty-twenty-twenty rule: every twenty minutes, look at something twenty feet away for twenty seconds.
Staring at screens for extended periods isn’t just tiring on the eyes, it’s dehydrating. Our blink rate decreases by about 50% during screen use, reducing the spread of tears across the eyes which naturally lubricates them. This practice leaves eyes feeling itchy and gritty. To combat this, make a conscious effort to blink more while working or watching. Incorporating specific eye exercises, like focusing on distant objects, can also help alleviate tension and promote healthy tear production.
2. Sleeping With a Fan On
While a fan can keep you cool and comfortable at night, it can also dry out the moisture in your eyes. The continuous flow of air can cause your tears to evaporate faster, worsening dry eyes. Consider using a humidifier in your room to maintain the air’s moisture balance.
Many people are unaware that sleeping with a fan blowing directly at them can contribute to dry eyes. Airflow can desiccate the tear film that protects your eyes, particularly while they’re closed and in a prolonged resting state. If a fan is necessary for comfort, try directing it away from your face and eyes to reduce the drying effect. A simple switch to a cooler sleep environment or adjusting the fan’s oscillation can make a big difference in maintaining eye moisture overnight.
3. Skipping Sunglasses on Cloudy Days
While it might seem unnecessary to wear sunglasses on days when the sun isn’t shining bright, UV rays can still penetrate clouds and wind can irritate your eyes, leading to dryness. Protecting your eyes with sunglasses can prevent irritation and keep them healthy.
Sunglasses are more than just a summertime accessory; they shield your eyes from harmful UV radiation every day, including overcast days. These rays can penetrate cloud cover and cause damage, which may contribute to dry eye conditions over time. Sunglasses also act as a barrier against wind and airborne irritants which can exacerbate dry eyes. Choosing a pair with UV protection ensures that your eyes are safeguarded against these invisible threats all year round.
4. Overuse of Artificial Tears
Although artificial tears can provide temporary relief, excessive use can actually exacerbate dry eyes. Over-reliance on these drops may mask the symptoms rather than address the underlying problem. It’s important to consult an eye care professional to determine the best treatment plan for your dry eyes.
Artificial tears might seem like a simple, convenient solution to dry eyes, but using them too frequently can lead to dependency and reduced natural tear production. Medicated drops, in particular, can contain preservatives that might irritate sensitive eyes. Instead of habitual use, focus on identifying and addressing environmental or lifestyle factors contributing to your discomfort. Consulting with an eye care specialist can help you understand your specific needs and avoid exacerbating the problem.
5. Wearing Contact Lenses Too Long
Wearing contact lenses for extended periods, especially the wrong type, can disrupt the natural tear film and lead to discomfort. Make sure to follow the instructions for your lens type and give your eyes regular breaks by wearing glasses when possible.
Lenses can constrain oxygen flow to your eyes, crucial for producing tears that keep eyes moist and comfortable. Many contact lens wearers extend the wear of their lenses beyond recommended durations, unaware of the drying effects this practice entails. The key is balance; give your eyes regular breaks and refresh them with appropriate drops. Transitioning back to glasses occasionally can significantly reduce discomfort and promote healthier eyes.
6. Not Drinking Enough Water
Dehydration can reduce tear production, leaving your eyes feeling dry and irritated. Staying well-hydrated is essential for maintaining your overall health and for keeping your eyes moist and comfortable. Aim for at least eight glasses of water a day to stay hydrated.
The role of hydration extends beyond skin and organ health—it plays an integral role in eye moisture too. Your body uses water to maintain the tear film that lubricates your eyes. If you’re working in a dry, indoor environment, or consume dehydrating beverages like coffee or alcohol, the demand for hydration increases. An easy routine change is always having water within reach and incorporating hydrating foods such as cucumbers and watermelon into your diet.
7. Exposure to Air Pollution
Air pollution and smog can irritate your eyes and worsen dryness. Consider wearing protective eyewear or avoiding outdoor exposure on days when pollution levels are high. Keeping your living space clean and air-filtered can also help mitigate these effects.
The invisible threat of air pollution not only risks respiratory health but also affects your eyes. Pollutants can interact with tears and reduce their effectiveness, leaving eyes vulnerable to dryness and irritation. On smoggy or high-pollution days, protective eyewear is an essential line of defense. At home, using air purifiers helps maintain a cleaner indoor air quality. Regularly cleaning vents and replacing air filters also supports a healthier living environment for your eyes.
