Blurry Vision: Possible Causes and Solutions

Things look very blurry..?

[Date] 2004/07/30 [Question] Inquirer: GD90 / Female / 21 Recently, I've been seeing things a bit blurry and white...
I can't quite describe it...
It's somewhat like the feeling you get after staring at a bright light for too long and then looking away, but it's not just a fixed point; everything I see looks like this.
I went to a clinic for an examination, but the doctor said he couldn't find anything wrong.
I asked if it was due to worsening myopia, and he said it wasn't.
He suggested that I schedule a detailed examination at a larger hospital, but I want to know the cause first since I currently can't find the time.
This blurriness happens not only when looking at distant objects but also when looking at close ones.
Even when I try to closely examine my fingernails, I have some issues.
I hope to get a response.
Thank you...

Chang Yan-Rui Hello, your condition is likely related to floaters, which often occur in myopic individuals in their 20s.
Most of the time, they cause semi-transparent, unclear objects to float in front of your eyes, but a small percentage may be related to retinal detachment, so it is essential to have a dilated retinal examination by an ophthalmologist.
Additionally, more severe dry eye syndrome may also present similar symptoms, so a thorough examination is necessary.
Thank you, and I wish you a speedy recovery.
However, I believe I have already undergone a dilated examination, and the doctor said there were no abnormalities on the surface of my eye.
He suspected there might be bleeding inside my eye, which is why he recommended a detailed examination at a larger hospital.
But I haven't hit my eye, so is it possible to have bleeding inside the eye? I wear contact lenses, and they are disposable ones.
Some people have suggested that I might have retinal vascular proliferation, which could lead to blurred vision.
Is that possible? Also, I went to an optical shop yesterday for a vision check, and they said I only have an increase of 50 degrees in one eye!

First, please do not panic, as it is reassuring to know that your eyes are generally fine.
However, based solely on your description, it is really difficult to provide you with a definitive answer.
Intraocular hemorrhage...
given your age, while it is not impossible, the likelihood is quite low.
If possible, please visit the ophthalmology department at Taipei City Hospital, Zhongxing Branch, where you will receive a more detailed response.

More Info

Blurry vision can be a frustrating and concerning symptom, especially when it affects your daily activities and overall quality of life. Based on your description, it seems that you are experiencing a persistent haziness in your vision, which is not limited to a specific distance but affects both near and far sight. This can be indicative of several underlying issues, and it's essential to explore these possibilities to find an appropriate solution.

Possible Causes of Blurry Vision
1. Refractive Errors: Although your recent eye exam indicated only a minor increase in your prescription, it's still possible that your vision could be affected by uncorrected refractive errors. Nearsightedness (myopia), farsightedness (hyperopia), and astigmatism can all lead to blurry vision. Even slight changes in your prescription can impact your visual clarity, especially if you are relying on outdated lenses.

2. Dry Eye Syndrome: This condition occurs when your eyes do not produce enough tears or when the tears evaporate too quickly. Symptoms can include a gritty sensation, redness, and blurred vision. Dry eyes can be exacerbated by environmental factors, prolonged screen time, or wearing contact lenses, especially if they are not properly maintained.

3. Floaters and Visual Disturbances: As you mentioned having a history of floaters, it's important to note that these can sometimes be accompanied by other visual disturbances, such as blurry vision. Floaters are usually harmless, but they can be a sign of more serious conditions like retinal detachment, especially if they are accompanied by flashes of light or a sudden increase in their number.

4. Cataracts: Although cataracts are more common in older adults, they can develop in younger individuals due to various factors, including trauma, certain medications, or underlying health conditions. Cataracts can cause a cloudy or blurry vision, and they typically progress slowly over time.

5. Neurological Issues: Blurry vision can also be a symptom of neurological conditions, including migraines or other disorders that affect the visual pathways in the brain. If you experience other symptoms such as headaches, dizziness, or changes in coordination, it may warrant further investigation.

Recommended Solutions
1. Comprehensive Eye Examination: Since your initial visit did not yield a definitive diagnosis, it is crucial to seek a comprehensive eye examination at a specialized facility. This should include a dilated fundus examination to assess the retina and vitreous for any abnormalities.

2. Update Your Prescription: If you have not had your prescription updated recently, consider getting a new pair of glasses or contact lenses that accurately reflect your current vision needs. Even a small change in prescription can significantly improve clarity.

3. Manage Dry Eye Symptoms: If dry eyes are suspected, consider using artificial tears or lubricating eye drops to alleviate symptoms. Additionally, practicing the 20-20-20 rule (taking a 20-second break to look at something 20 feet away every 20 minutes) can help reduce eye strain.

4. Monitor for Changes: Keep track of any changes in your vision, including the frequency and duration of blurry episodes. If you notice an increase in floaters or flashes of light, seek immediate medical attention.

5. Lifestyle Adjustments: Ensure that you are maintaining a healthy lifestyle, including a balanced diet rich in vitamins A, C, and E, omega-3 fatty acids, and antioxidants, which can support eye health. Staying hydrated and managing stress can also be beneficial.

6. Follow-Up Care: If your symptoms persist despite taking these steps, follow up with your eye care provider. They may recommend additional tests or referrals to specialists, such as a retinal specialist or a neurologist, depending on your symptoms.

In conclusion, while blurry vision can be caused by various factors, it is essential to pursue a thorough evaluation to identify the underlying cause. Early detection and intervention can significantly improve your visual health and overall well-being. Don't hesitate to seek further medical advice if your symptoms continue or worsen.
