Key Takeaways

  • Screen time and dry eye can lead to discomfort behind your eyes.
  • Pain behind a single eye can indicate tension or a migraine.
  • Sudden vision changes indicate the need for prompt medical attention.
  • Taking regular screen breaks can help reduce daily eye fatigue.
  • Routine visits to an eye doctor in Vancouver, WA, support long-term vision health.

If you’ve been experiencing pain or discomfort that feels like it’s coming from behind your eye, you may be wondering what’s going on and how to find relief. Our team at Precision Eye Care understands that this type of discomfort can make day-to-day activities difficult, which is why we want to help you understand what may be causing it and how to find relief.

Pain behind your eyes can stem from a few causes, including digital eyestrain, dry eye, or sinus pressure. Some cases of discomfort can be handled at home, but if you experience sudden vision changes, severe pain, or pain that persists or worsens, seek prompt medical or eye care.

Common Sources of Pain Behind Your Eye

Digital Eyestrain and Fatigue

In our increasingly digital world, many of us spend hours each day looking at computers and phones. Staring at screens for long periods can make your eye muscles work hard to maintain focus, which can contribute to discomfort over time.

On top of that, we tend to blink less when looking at screens, which can add to symptoms of dry eye disease.

Dry Eye Disease

When your tear film is healthy and balanced, it keeps your eyes lubricated and comfortable without you really thinking about it. But if something is wrong with this system, it can lead to uncomfortable dry eye symptoms.

If you notice any of these signs, you may be experiencing dry eye:

  • A gritty, scratchy feeling, like a piece of sand is stuck in your eye.
  • Excessively watery eyes, which can be your body’s response to the irritation.
  • Red or irritated eyes.
  • Blurry vision that comes and goes.

At Precision Eye Care, we have the tools and technology to treat your individual case of dry eye, so you can get back to feeling comfortable.

Sinus Issues and Pressure

Your sinuses sit right behind and around your eye sockets. When a cold or allergy inflames these cavities, they fill with fluid and swell against the surrounding nerves, which can cause discomfort behind your eyes.

Why Pain Happens Behind Only One Eye

Migraine Headaches

Pain on one side of your face can sometimes indicate a migraine headache. These intense episodes can disrupt your entire day and make normal tasks feel impossible. If you have a migraine, you may be experiencing some of these symptoms:

  • Intense throbbing focused entirely behind a single eye.
  • Visual disturbances, such as flashing lights, shimmering patterns, or blind spots.
  • Discomfort that increases when you encounter loud sounds or bright lights.

If you notice severe vision changes alongside intense pain, that’s a sign to seek emergency eye care promptly.

Dental Issues and Jaw Tension

Your facial nerves connect your jaw directly to the area around your eyes. If you clench your teeth at night, that can put intense stress on these shared nerve pathways and send referred pain to your eye area.

Sometimes dental issues can cause pain in other places in the body. A tooth infection, for example, can send pain all throughout the face, including the eye area. If the discomfort gets worse when you bite down, it’s a good idea to book an appointment with your dentist.

When to Seek Emergency Eye Care

Signs You Need Immediate Help

In many cases, eye discomfort fades with rest and hydration. However, certain symptoms require a prompt visit to an optometrist to protect your long-term vision. If these signs sound familiar, it’s a good idea to seek professional care as soon as you can:

  • The discomfort develops very quickly and is very intense.
  • You experience sudden or significant changes in vision, like blurriness, flashes or floaters, or a noticeable drop in vision quality.
  • You have a high fever combined with eye pain, which could indicate an infection.

Glaucoma Symptoms

Some types of glaucoma occur when fluid inside the eye cannot drain properly, causing eye pressure to rise quickly. This condition requires rapid medical intervention to help protect your optic nerve (which sends signals to the brain) from lasting damage.

If you notice pain, halos around lights, or nausea, you should seek emergency eye care promptly.

How to Reduce Eye Pain at Home

In cases that aren’t emergencies, it can be helpful to know how to find relief at home.

The 20-20-20 Rule

An easy way to manage digital eye strain is to give your eyes a short break from the devices. The 20-20-20 rule is easy to remember and helps your eye muscles relax and reset during long work shifts. Every 20 minutes, look at something 20 feet away for 20 seconds.

Simple Home Adjustments

Small environmental changes can improve your daily comfort. These basic steps can help support a healthy tear film and reduce muscle strain. For dry eye, we can provide a microwaveable eye mask to support oil flow in the glands lining your eyes.

If you work on a computer, try to make sure that your screen and the room around you are in similar lighting, lower your screen brightness to reduce glare, and try to look slightly down at your computer instead of straining your neck to look upwards.

How an Eye Doctor Can Help

Dry Eye Therapy

For some people, persistent dry eye requires more than just over-the-counter drops. Our team at Precision Eye Care provides comprehensive eye care, including innovative dry eye therapy. We offer options to help keep your eyes comfortable and hydrated, including modern technology, medical skin care, and gentle esthetic treatments.

Modern Frames and Routine Eye Care

If your prescription is outdated, it may be causing some of your discomfort. In that case, updating your glasses can help reduce strain and sharpen your vision. A routine exam also gives the eye doctor a chance to catch early warning signs of larger health issues.
