Can Blurry Vision Be Temporary? When to Worry
Submitted by Michael J. Elman, M.D. on October 15, 2025

Blurry vision is a common complaint that can range from a minor inconvenience to a sign of a serious eye condition. Sometimes it’s temporary and resolves quickly, while in other cases it may signal the need for immediate medical attention. At Elman Retina Group, our board-certified retina specialists in Baltimore evaluate patients daily to identify the causes of blurry vision and provide advanced treatment options tailored to each individual case. Knowing when to seek help is a crucial step in protecting your vision.
Everyday Causes of Temporary Blurriness
Not all blurry vision is a cause for alarm. Fatigue, dry eyes, or digital eye strain can cause your vision to appear hazy, especially after prolonged periods of reading or computer use. Certain medications may also cause temporary changes in clarity. Even dehydration can impact the eyes, causing blurred vision until fluids are replenished. In these cases, vision usually returns to normal with rest, hydration, or eye lubrication.
When Blurry Vision Signals an Eye Condition
Persistent or sudden blurry vision should not be ignored. Conditions such as diabetic retinopathy, macular edema, or age-related macular degeneration can affect the retina and cause lasting vision changes if untreated. A retinal tear or detachment may also begin with sudden blurriness, often accompanied by flashes of light or new floaters. These situations require urgent evaluation, as early treatment can prevent permanent vision loss.
The Role of Systemic Health
Sometimes blurry vision relates to broader health issues. Fluctuating blood sugar levels in people with diabetes may cause temporary visual changes, but they also increase the risk of long-term retinal damage. High blood pressure, vascular disease, or migraine headaches can similarly affect vision. Because eye health is connected to overall health, it’s important to share your full medical history with your eye specialist.
When to Schedule an Exam
If blurred vision is brief and resolves with rest or hydration, it may not be a sign of disease. However, recurring or sudden blurriness, especially when accompanied by eye pain, light sensitivity, floaters, or loss of part of the visual field, should prompt an immediate appointment with a retina specialist. Comprehensive exams and imaging tests such as optical coherence tomography (OCT) allow doctors to identify subtle retinal changes before they lead to significant vision loss.
