Blurry Vision: Possible Causes and Solutions

Blurred vision for nearly two weeks?

I have myopia in both eyes, with a prescription of -3.75 diopters, which has remained stable for a long time.
1.
"I received the nine-valent HPV vaccine on October 17 this year." The next day, I noticed something unusual with my eyes, but it wasn't blurry.
About three days later, my vision suddenly became blurry, especially in my left eye.
Although I am unsure if there is any correlation between the two events, my left eye has been blurry for over a week, both for near and distance vision (I already have myopia).
My right eye is normal.
I visited both a clinic and a large hospital, and they told me that my eye examinations showed no issues.
2.
"Could this be due to astigmatism or presbyopia?" The blurriness feels like my eyes cannot focus...
no matter how much I rest my eyes, it remains blurry...
However, the doctors I consulted could not provide any explanations.
Six months ago, I underwent 3.
"fat grafting and capsular repair surgery," but my vision was normal post-surgery.
Could this recent blurriness be related to that? My vision suddenly became blurry overnight, specifically in my left eye, while my right eye remains normal.
4.
"Moreover, when I had my vision checked, they said my left eye has changed to -2.20 diopters, but even with -2.20 lenses, my vision is still unclear.
What could be the reason for this?" Thank you for your help, doctor.

More Info

Blurry vision can be a frustrating and concerning symptom, especially when it appears suddenly or changes over time. Based on your description, there are several potential causes for the blurry vision in your left eye, and I will address them in detail.

1. Post-Vaccination Effects: You mentioned receiving the nine-valent HPV vaccine shortly before experiencing blurry vision. While vaccines can cause temporary side effects, including mild visual disturbances, there is no established direct link between the HPV vaccine and significant vision changes. However, if your blurry vision coincided with the vaccination, it might be worth discussing with your healthcare provider to rule out any unusual reactions.

2. Refractive Changes: Given that you have a history of myopia (nearsightedness) with a prescription of -3.75 diopters, it is possible that your vision has changed. The sensation of being unable to focus, particularly if it is more pronounced in one eye, could indicate a shift in your refractive error. This can happen due to various factors, including stress, fatigue, or even changes in the eye's lens flexibility, which can lead to presbyopia (difficulty focusing on close objects) as you age. It is advisable to have a comprehensive eye exam to reassess your prescription and determine if any changes have occurred.

3. Corneal or Lens Issues: Blurry vision can also arise from problems with the cornea or lens of the eye. Conditions such as corneal edema, cataracts, or changes in the lens due to surgery could lead to visual disturbances. You mentioned having undergone surgery for fat pad retraction; while this typically does not affect vision, any surgical procedure can lead to temporary changes in vision due to swelling or healing processes. If your left eye is experiencing persistent blurriness, it may be beneficial to have a detailed examination of the cornea and lens.

4. Visual Processing Issues: Sometimes, the brain's ability to process visual information can be affected, leading to symptoms like blurry vision. This can occur due to stress, fatigue, or even migraines. If you have a history of ocular migraines, this could be a contributing factor. Ensuring adequate rest and managing stress levels can help alleviate these symptoms.

5. Optic Nerve or Retinal Issues: Although you have had comprehensive eye exams that did not reveal any significant issues, it is essential to consider that some conditions affecting the optic nerve or retina may not be immediately apparent. If your blurry vision persists or worsens, further evaluation, including imaging studies, may be warranted to rule out any underlying conditions.

6. Visual Acuity Testing: You mentioned that your left eye's vision was measured at 2.20 diopters, but wearing corrective lenses did not improve clarity. This discrepancy could indicate that the prescription is not accurately addressing your current visual needs. It is crucial to ensure that your glasses or contact lenses are appropriately prescribed and fitted.

In conclusion, blurry vision can stem from various causes, including refractive changes, corneal or lens issues, visual processing problems, or even post-surgical effects. It is essential to follow up with your eye care provider for a thorough examination and possibly additional testing to determine the underlying cause of your symptoms. Keeping a record of when the blurriness occurs, any accompanying symptoms, and how it affects your daily activities can also provide valuable information for your healthcare provider. Remember to prioritize your eye health and seek timely medical advice to address your concerns effectively.
