5 Conditions That Can Cause Blurry Vision

April 7, 2026, 4:12 PM
At Olson Optical, we help patients understand that blurry vision is not a condition to ignore. Sometimes it comes from a simple prescription change, but it can also point to a larger eye health issue. Our approach to optometry focuses on identifying the cause early, protecting long-term vision, and recommending the right treatment based on what we find during a comprehensive eye exam.

1. Refractive Errors

Nearsightedness, farsightedness, and astigmatism are some of the most common reasons for blurry vision. These problems happen when light does not focus properly on the retina. We diagnose refractive errors during an eye exam and may correct them with updated glasses or contact lenses that match your visual needs.

2. Dry Eye

Dry eye can make vision fluctuate throughout the day, especially during screen use, reading, or driving. When the tear film becomes unstable, the surface of the eye cannot stay smooth and clear. We evaluate tear quality, identify contributing factors, and recommend treatment that may include lubricating drops, changes in visual habits, or other supportive care.

3. Cataracts

Cataracts can make vision look cloudy, dim, or hazy. Many patients also notice more glare at night or trouble reading in low light. We look for cataracts during routine visits and monitor how much they affect daily life. When needed, we guide patients through the next step in care.

4. Glaucoma

Glaucoma can damage the optic nerve and affect vision gradually. In many cases, it does not cause obvious symptoms at first. That is why regular eye exams matter. We screen for glaucoma, track suspicious changes, and help patients protect their sight through early detection and ongoing management.

5. Macular Degeneration

Macular degeneration affects central vision and can make faces, words, and fine detail harder to see. We use eye exams and diagnostic evaluation to look for early signs and help patients respond quickly when changes appear.
