What Causes Dry Eyes All of a Sudden?

Your eyes feel fine 1 moment, and the next, they’re scratchy, red, and irritated. Our team at Dry Eye Relief knows how frustrating this sudden change can be and how uncomfortable it is to not know what’s causing it. 

Sudden dry eye symptoms often occur when your tear system is unable to properly lubricate your eyes. This can be due to environmental factors, a change in tear quality, or a decrease in tear production, which we can identify and begin to treat after a comprehensive dry eye assessment.

Common Symptoms of Sudden Dry Eye

Dry eye is a common condition where your tears aren’t able to lubricate your eyes properly. This discomfort can show up in several ways, often affecting both of your eyes at the same time. Common signs include:

  • A scratchy or burning feeling
  • Redness and light sensitivity
  • The sensation that something is in your eye
  • Watery eyes, which can be your body’s response to the irritation
  • Blurry vision or eye fatigue

Reasons Your Tears Can’t Keep Up

Healthy tears have a specific balance of water, oil, and mucus. This mix helps keep your eyes lubricated and clear, but when this balance is off, you might experience sudden dryness. It’s important to note that most cases of dry eye are caused by a combination of factors.

You Produce Fewer Tears

Sometimes, your body just doesn’t make enough of the watery part of tears. This can happen as you get older or because of certain health conditions. Some medications you might take for allergies or a cold can also affect tear production.

Your Tears Evaporate Too Fast

Your tears have an oily outer layer that prevents them from drying up too quickly. This oil comes from tiny meibomian glands that line your eyelids. If these glands get blocked, your tears evaporate before they can do their job. This condition, called meibomian gland dysfunction (MGD), is a very common reason for dry eye.

What Triggers Sudden Dry Eye Episodes?

Your daily life and surroundings can play a big role in why your eyes suddenly feel dry. Certain situations can make symptoms appear or feel more noticeable.

Your Daily Environment and Habits

Things like air conditioning, car heaters, or a windy day can dry out your eyes quickly. Spending a lot of time looking at a computer or phone screen also makes a difference because you might tend to blink less often, which means your tears aren’t spread across your eyes as frequently. This is often referred to as digital eye strain.

Health and Lifestyle Factors

Wearing certain types of contact lenses can contribute to dry eye discomfort for some people. Other factors, like hormonal changes, can also affect tear production. A diet low in vitamin A or omega-3 fatty acids may also play a part in eye health and comfort.

Simple At-Home Steps for Relief

You can make small changes to your daily routine that may help you feel more comfortable. These simple steps can help reduce irritation from environmental triggers.

  • Add moisture to the air: A humidifier in your home or office can help, especially during dry winter months.
  • Take screen breaks: Follow the 20-20-20 rule. Every 20 minutes, look at something 20 feet away for 20 seconds. This helps your eyes relax and blink more.
  • Use artificial tears: Over-the-counter drops can provide temporary relief when your eyes feel dry.

While these tips can offer temporary comfort, they may not address the underlying factors contributing to your dryness. For more persistent symptoms, exploring professional dry eye treatments can provide more targeted relief.

When to See a Dry Eye Doctor

If simple changes don’t provide relief and your symptoms persist, it may be time to seek a professional opinion. It’s a good idea to schedule an appointment if you experience:

  • Dryness, redness, or pain that lasts for a long time
  • Difficulty with activities like reading or driving at night
  • Changes in your vision
