A problem in any part of the eye can cause sudden blurry vision, but when present in only one eye, it may be a medical emergency. It should be evaluated and treated by a physician as soon as possible — to prevent permanent damage and vision loss.
Sudden blurry vision may be the body’s warning about a serious health problem. Prompt medical treatment can lead to the best possible outcome.

The following warning signs may be an indication of a serious eye problem. If you experience even one of these, seek emergency medical services immediately for evaluation and treatment:
- sudden unexplained change in your vision (e.g., blurred vision)
- eye pain
- eye injury
- signs of a stroke, such as a facial droop, one-sided weakness, or difficulty speaking
- marked vision impairment — especially if only in one eye
- loss of one aspect of the visual field
- sudden blurred vision secondary to a weakened immune system due to conditions like HIV or chemotherapy treatment
