Your vision might be blurry at night due to a few reasons, often related to how your eyes adjust to lower light conditions.
Possible Causes of Blurry Night Vision
According to the provided reference, blurry night vision can often be attributed to:
- Refractive Errors: Uncorrected or under-corrected refractive errors like nearsightedness, farsightedness, or astigmatism can significantly impact your night vision. If you need glasses or contacts but aren't wearing them (or your prescription is outdated), your vision may be blurry, particularly in low light.
Detailed Explanation
When it's dark, your pupils dilate to let in more light. If you have a refractive error, this dilation can make the blurriness more noticeable. Here's a breakdown:
- Nearsightedness (Myopia): Difficulty seeing distant objects clearly, which worsens at night.
- Farsightedness (Hyperopia): Difficulty seeing near objects clearly, and this can also cause strain and blurriness at night.
- Astigmatism: Blurred vision at all distances due to an irregularly shaped cornea. Nighttime glare and blur can be more pronounced.
What to Do
If you experience blurry night vision, consider the following:
- Eye Exam: Schedule a comprehensive eye exam to determine if you have a refractive error or if your current prescription needs updating.
- Corrective Lenses: Wear your prescribed glasses or contact lenses consistently, especially at night.
- Discuss Concerns: Talk to your eye doctor about your specific nighttime vision issues. They can provide personalized advice and rule out other potential causes.
