Blurry Vision? Common Causes and When to Book an Eye Exam
Carlsbad, N.M. – November 10, 2026 -- If your vision has turned blurry suddenly or has worsened gradually, the cause may be as simple as an outdated glasses prescription or as serious as glaucoma. Optometrist Dr. Spencer Franz of Vision Source Carlsbad lays out the most common culprits and says when to book an exam in a HelloNation article.
An outdated prescription often causes the first symptoms
Vision changes naturally over time, and a shift in glasses or contact lens prescriptions is one of the most frequent causes of blur. Eye strain and headaches can appear long before the blur becomes obvious. A routine exam catches these changes early so the correction can be updated.
