Plenty of people live with dry eye for months before they put a name to it. The early signs feel a lot like being tired, so it’s easy to shrug them off.
Yes, dry eye can cause blurry vision, and that blurriness usually comes and goes instead of sticking around. Once you recognize the pattern, you can describe it during your next eye exam and ask whether a dry eye assessment makes sense for you.
How Dry Eye Leads to Blurry Vision
Your eye relies on a thin coating of tears, called the tear film, to keep its front surface smooth. When that film stays stable, light passes through it cleanly and focuses on the back of your eye.
With dry eye, the tear film breaks up too fast or covers the surface unevenly. Light scatters across those uneven patches, so what you see looks hazy. Every blink spreads a fresh layer of tears across your eye. That’s why your vision may clear for a moment and then fade again a few seconds later.
Other Dry Eye Symptoms to Watch For
Blurry vision often comes with other symptoms, and it’s easy to blame them on a long day. Watch for a few of these:
- A gritty or scratchy feeling, like something’s stuck in your eye
- Burning
- Redness
- Sensitivity to bright light
Watery eyes can happen too. It sounds backwards, but when your tears evaporate too quickly, your eyes may respond by making extra watery tears that don’t solve the problem.
If you wear contacts, you might notice lenses that feel fine in the morning and scratchy by evening. Some people also see glare or halos around headlights when they drive at night.
Signs in Kids and Teens
Children rarely say “my eyes are dry.” Instead, they rub their eyes during homework, push the tablet away, or complain after a long gaming session.
Children use screens for school and for fun, so they can run into the same blinking problems adults do. Mention anything you’ve noticed at home during your child’s next eye exam.
What Causes Dry Eye
Dry eye usually starts with 1 of 2 problems. Either your eyes don’t make enough tears, or the tears they make evaporate too quickly. When tears dry up fast, the oil glands along your eyelids are often involved. These glands add a thin layer of oil on top of your tears to slow evaporation, and when they clog, your tears don’t last as long.
Your surroundings can make it worse. A car heater aimed at your face can dry out your eyes on a short drive, while ceiling fans and air conditioning do it more slowly, especially overnight.
Screens play a big role, too. People blink less often when they focus on a screen, which gives your tear film more time to break up between blinks. Contact lenses can also make your eyes feel drier because they sit right on the tear film.
When to See an Optometrist About Blurry Vision
Blurriness that clears when you blink often points to dry eye. If your vision stays blurry, doesn’t change when you blink, or keeps coming back, it’s time for a closer look. Sudden changes and eye pain shouldn’t wait. Book an appointment if any of these sound familiar:
- Sudden blurry vision
- Eye pain
- Any loss of vision
- Symptoms that don’t improve with rest or eye drops
- New glasses that still leave your vision fuzzy
How to Ease Dry Eye at Home
A few small changes to your routine can help your eyes feel more comfortable. Take regular breaks from your screen and blink a few times fully during each one. Set your monitor slightly below eye level. You’ll look down a little, and your eyelids will cover more of the surface of your eye.
Run a humidifier in your bedroom if the air in your home feels dry. Outside, wraparound sunglasses can block wind, and artificial tears can help keep your eyes comfortable during the day.
If your symptoms keep returning, our Dry Eye Clinic can help you figure out what’s behind them.
What Happens During a Dry Eye Assessment
Your optometrist will check how quickly your tear film breaks up and examine the oil glands along your eyelids. We also use imaging of your tear film and glands to see details that are hard to spot otherwise.
From there, we’ll put together a treatment plan based on what we find. Follow-up visits let us see how your eyes respond and adjust your plan if needed.
Clearer, More Comfortable Eyes Start with an Exam
You don’t have to keep blinking your way through the workday. Our optometrists can look at the surface of your eyes and walk you through what’s happening, so you can decide on next steps together.
