Blurry Vision That Comes and Goes? It Might Be Dry Eye

Ever notice your vision gets blurry while reading, working at the computer, or driving—but then suddenly clears after you blink? This on-again, off-again clarity is a textbook sign of tear film instability, a key indicator of dry eye disease.

At Eyes on the Lake in Milwaukee, Dr. Vaugn Schneider sees patients with this exact symptom almost daily. The good news? Once you understand what’s happening, you can take steps to fix it.

What’s Really Causing the Blur?

Your eye’s surface is coated in a thin layer of tears called the tear film. This film is essential for maintaining clear, stable vision. Every time you blink, you refresh that layer.

When your tear film breaks up too quickly or doesn’t evenly coat the eye, it leads to momentary blurring. Blink, and it clears—until the next time it dries out.

Common Causes of Tear Film Instability

Meibomian Gland Dysfunction (MGD): These glands produce the oily layer of the tear film. If they’re blocked or atrophied, your tears evaporate too quickly.
Incomplete Blinking: Especially common with screen use. If you’re not fully blinking, your tear film doesn’t spread properly.
Poor Tear Quality: Even if your eyes make enough tears, the composition may be unbalanced—too little oil or mucin.

Does This Sound Like You?

Vision is clear in the morning but gets blurry during the day
Reading or screen time causes hazy, inconsistent focus
Blinking makes your vision snap back into clarity
Dryness, grittiness, or eye fatigue accompany the blur

These are all strong indicators of ocular surface disease, and often go overlooked.

How Dr. Schneider Can Help

At Eyes on the Lake, we go beyond basic eye exams to evaluate the health of your tear film and the function of your meibomian glands.

Your personalized treatment plan may include:

Meibomian gland imaging to assess atrophy or blockages
IPL therapy to restore gland function and reduce inflammation
Blink training and digital hygiene coaching
Nutrition and hydration recommendations to improve tear quality
Artificial tears or prescription drops tailored to your tear profile

You Deserve Clear, Consistent Vision

Blurry vision that fluctuates isn’t just an annoyance—it’s a sign that your eyes aren’t functioning at their best. Treating the underlying cause gives you back control, clarity, and comfort.
