When it comes to understanding blurry vision, particularly when you notice that only the center of your vision is clear while the edges appear blurred, there are several potential causes and considerations. Your symptoms, including itchy eyes and the presence of floaters, suggest a few possible conditions that may be affecting your eye health.

Firstly, the blurry vision you describe, where the center is clear but the edges are not, could be indicative of several issues. One common cause is astigmatism, a refractive error that occurs when the cornea or lens of the eye is irregularly shaped, leading to distorted or blurred vision at all distances. Another possibility is that you may be experiencing symptoms related to dry eye syndrome, which can cause discomfort, itchiness, and blurred vision, especially when focusing on screens or reading for extended periods.

Regarding your question about the medications prescribed by your doctor—chloramphenicol (an antibiotic) and a lubricant eye drop like護康視 (which is likely a preservative-free artificial tear)—it is generally safe to use both medications simultaneously, but you should follow the specific instructions provided by your healthcare provider. Typically, it is recommended to wait a few minutes between applying different eye drops to ensure that each one can be absorbed effectively without washing out the previous drop.

As for your concern about dry eyes, this condition is characterized by a lack of sufficient lubrication on the surface of the eye, leading to symptoms such as itchiness, redness, and blurred vision. Factors contributing to dry eyes include prolonged screen time, environmental conditions (like wind or dry air), and certain medications. If you suspect you have dry eye syndrome, it is essential to discuss this with your eye care professional, who may recommend additional treatments or lifestyle changes to help manage your symptoms.

Regarding the increase in floaters, these are typically harmless and are caused by changes in the vitreous gel inside the eye as we age. However, if you notice a sudden increase in floaters, especially if accompanied by flashes of light or a shadow in your peripheral vision, it is crucial to seek immediate medical attention, as these could be signs of a retinal tear or detachment, which requires prompt treatment to prevent vision loss.

In summary, your symptoms of blurry vision, itchiness, and increased floaters warrant a thorough evaluation by an eye care professional. They can provide a comprehensive eye exam to determine the underlying causes of your symptoms and recommend appropriate treatments. Additionally, maintaining good eye health through regular check-ups, proper hydration, and taking breaks during prolonged screen time can help mitigate some of the discomfort you are experiencing. If you have any further questions or concerns, do not hesitate to reach out to your healthcare provider for personalized advice and treatment options.
