You’re reading something on your phone, and your vision goes totally blurry for a moment. You blink a few times, and it clears up, but a few minutes later, it happens again. At Thornhill Vision Care, we know that this can be confusing and frustrating, which is why our team is here to help you understand what may be happening.
Yes, dry eye can cause temporarily blurry vision. Your tears are meant to form a smooth layer across the front of your eye, but when you have dry eye, it can cause patchiness, meaning light will scatter instead of focusing clearly. Blinking can help smooth out that layer, which is why things briefly sharpen after you blink.
Common Symptoms of Dry Eye
With dry eye, blurry vision is just 1 piece of the picture. Though everyone experiences the symptoms differently, if you have dry eye, you may notice:
- A stinging, burning, or gritty feeling, like something is in your eye
- Redness or sensitivity to light
- Excessively watery eyes, which can be your body’s response to the irritation
- Discomfort with contact lenses or after long stretches of screen time
Some people with dry eye notice that these symptoms get worse throughout the day, especially in drier environments or after focusing on a screen for hours. If this sounds familiar, you’re not imagining it, but there is real relief available.
What Leads to Dry Eye and Blurry Vision
Screen Time and Reduced Blinking
People tend to blink less often when looking at a screen. Fewer blinks mean the tear film dries out faster, and that can contribute to blurriness and discomfort over time. A simple habit that can give your eyes a chance to rest is the 20-20-20 rule. Every 20 minutes, look at something 20 feet away for 20 seconds.
Contact Lenses and Environmental Factors
Some contact lenses can affect the stability of your tear film throughout the day. Over time, that can leave your eyes feeling dry and your vision feeling less sharp. Outside factors play a role too. Dry air, wind, and smoke can all impact how quickly your tears evaporate, leaving your eyes more exposed.
Who Is More Likely to Experience Dry Eye?
Dry eye doesn’t affect everyone equally. Women going through hormonal changes, including pregnancy, perimenopause, or menopause, are more likely to develop it. Adults over 50 also tend to produce fewer tears naturally as part of the aging process. If you fall into either group and you’ve been noticing more eye discomfort lately, dry eye is a reasonable place to start a conversation with an eye doctor.
How Long Dry Eye Blurriness Can Last
How long the blurriness lasts depends on what’s contributing to it and whether it’s being addressed. For many people, blurriness tied to dry eye is temporary. It clears up after blinking, using lubricating drops, or stepping away from a screen.
Persistent blurriness that doesn’t improve with basic measures is a different situation. If your blurriness doesn’t clear with blinking, you may have another vision or eye health issue that requires evaluation.
If the blurriness keeps showing up, a comprehensive eye exam can help clarify what’s actually going on.
Dry Eye Treatment Options
At-Home Relief
For mild dry eye, there are practical steps you can take to help relieve your symptoms. Preservative-free artificial tears are gentle on the eye’s surface and can be used as often as needed throughout the day. Warm compresses applied to the closed eyelids for several minutes can help loosen blockages in the oil glands along the edges of your eyelids. Those glands contribute to a stable tear film, so keeping them flowing can help support your eye comfort.
In-Clinic Dry Eye Treatments
When at-home care isn’t enough, there are in-clinic options worth knowing about. Prescription anti-inflammatory drops can help reduce the underlying irritation associated with dry eye. Intense pulsed light therapy (IPL) and radiofrequency (RF) therapy are 2 in-clinic treatments that target meibomian gland dysfunction, a common contributing factor to dry eye in which the oil glands along your eyelids aren’t functioning properly.
Our eye doctor in Thornhill can assess whether these options are a fit for your situation and tailor their recommendations to your specific case of dry eye. We have a wide variety of options designed for dry eye, so if you feel like you’ve tried everything and nothing is working, we’d love to see you.
