Blurred Vision: Eye Health Concerns and Solutions - Ophthalmology

Hello! Thank you for your detailed question regarding your eye health concerns. It sounds like you're experiencing a complex set of issues with your vision, particularly with the differences in clarity between your left and right eyes, as well as some discomfort and symptoms like increased tearing and nasal congestion.

Firstly, the difference in visual clarity between your two eyes can be attributed to several factors, including the degree of refractive error (myopia, hyperopia, astigmatism) and the health of the eye structures themselves. Given that you have high myopia (over 800 degrees in one eye and nearly 700 in the other), it's not uncommon to experience variations in visual acuity. The fact that your right eye has increased flashes of light and feels weaker could indicate a few possibilities, such as fatigue of the ciliary muscle (which helps focus the lens), or even early signs of retinal issues, especially in the context of high myopia.

The term "偏視" (which translates to "strabismus" or "squint") suggests that your eyes may not be properly aligned, which could also contribute to the blurred vision and discomfort you are experiencing. This misalignment can lead to double vision or difficulty focusing, particularly when using both eyes together. It's crucial to have a comprehensive eye examination to assess for any underlying conditions that could be causing these symptoms.

Regarding your symptoms of increased tearing and nasal congestion, these could be related. The eyes and nasal passages are interconnected through the nasolacrimal duct, which drains tears from the eyes into the nasal cavity. If you have chronic nasal congestion, it could potentially affect tear drainage and lead to excessive tearing. Additionally, if you are experiencing eye strain from prolonged screen time, this could exacerbate discomfort and lead to symptoms like redness and tearing.

To address your concerns, here are some recommendations:
1. Regular Eye Exams: It's essential to have regular check-ups with an eye care professional. They can monitor your vision and eye health, especially given your high myopia and the symptoms you're experiencing.

2. Corrective Lenses: Ensure that your glasses prescription is accurate. If you're still experiencing blurred vision with your new glasses, it may be worth revisiting your optometrist or ophthalmologist to reassess your prescription. Sometimes, a slight adjustment in the lens power or type (e.g., progressive lenses, bifocals) can make a significant difference.

3. Eye Strain Management: Since you mentioned being a heavy smartphone user, consider implementing the 20-20-20 rule: every 20 minutes, take a 20-second break to look at something 20 feet away. This can help reduce eye strain.

4. Artificial Tears: If you are experiencing dryness or excessive tearing, using preservative-free artificial tears can help maintain moisture in your eyes and alleviate discomfort.

5. Nasal Congestion: If your nasal congestion is persistent, consider consulting with an ENT specialist. They can evaluate whether there are underlying issues such as allergies or structural problems that may be contributing to your symptoms.

6. Healthy Lifestyle: Maintaining a balanced diet rich in vitamins and antioxidants (like lutein and zeaxanthin) can support eye health. Staying hydrated and getting adequate sleep is also crucial for overall well-being.

7. Limit Screen Time: Reducing the amount of time spent on screens, or using blue light filters, can help minimize eye strain and improve comfort.

In conclusion, your symptoms warrant a thorough evaluation by an eye care professional to rule out any serious conditions and to ensure that your corrective lenses are appropriate for your needs. With the right management and care, many of these issues can be addressed effectively. Don't hesitate to seek further medical advice if your symptoms persist or worsen. Your eye health is important, and taking proactive steps can lead to better outcomes.
