Optometry Expert Dr. Kimberly Arnett Explains When a Prescription Change May Not Explain Blurry Vision in HelloNation

The Article Reviews Common Causes of Blurry Vision and Explains When Changes in Visual Clarity May Need Closer Evaluation.

FLORENCE, Ky., Oct. 16, 2026 /PRNewswire/ -- What can cause blurry vision besides a prescription change? HelloNation published an article featuring insights from Optometry Expert Dr. Kimberly Arnett of Arnett Vision Care in Florence, Kentucky, that answers this question.

The article explains that blurry vision can have many possible causes. While changes in nearsightedness, farsightedness, or astigmatism may affect visual clarity, a change in prescription is only one possibility.

According to the article, dry eye is a common cause of hazy or fluctuating vision throughout the day. Tears create a smooth surface across the front of the eye. When that tear film becomes unstable, light may not focus as clearly.

The HelloNation article also describes how digital eye strain can affect visual comfort and clarity. Extended computer or phone use may reduce blinking and contribute to dryness. Some people experience blurry vision after focusing on a screen at one distance for several hours.

Contact lens problems can produce similar symptoms. The article notes that lenses may dry out, shift slightly, or accumulate deposits that interfere with clear vision. Wearing contact lenses longer than recommended may also increase irritation and reduce visual stability.

The article explains that changes in the eye's focusing ability can also affect vision over time. Adults may gradually have more difficulty focusing on close work as the eyes lose some flexibility with age. An eye exam can help determine whether these changes are related to focusing or another cause.

However, the article emphasizes that blurry vision may involve more than a change in prescription. Changes affecting the cornea, lens, retina, or optic nerve can influence visual clarity. Cataracts, for example, can gradually make vision cloudy and reduce contrast, especially in dim light.

The article also notes that blood sugar changes can temporarily affect how the eye focuses. Certain medical conditions and medications may also affect vision. A complete health history can therefore provide useful information during an eye exam.

Optometry Expert Dr. Kimberly Arnett is featured as the source of insights for the article's discussion of these possible causes. The article explains that the timing and pattern of blurry vision can provide important clues when determining what may be affecting eye health.

Vision that becomes unclear after screen use may have a different cause from vision that remains blurry throughout the day. Symptoms affecting one eye may also require a different evaluation than symptoms affecting both eyes.

The article identifies additional symptoms that may require prompt attention, including eye pain, redness, flashes of light, new floaters, double vision, headaches, or sudden vision loss. Do not treat sudden or severe changes as a routine prescription change.

A comprehensive eye exam looks beyond how clearly someone can read an eye chart, according to the article. It may assess focusing ability, eye coordination, the eye's front surface, and internal eye health. This broader evaluation can help distinguish ordinary vision changes from conditions affecting the eye itself.

The article concludes that understanding when blurry vision began, how often it occurs, and whether other symptoms are present can help identify its cause.
