Myopia
I have myopia of about 50-75 degrees in my right eye, while my left eye is normal.
I have been using dilating drops long-term and have check-ups every six months.
However, I am unsure about what maintenance methods can help correct my vision over a year and a half.
Do dilating drops really help? Is it necessary to wear UV-protective sunglasses?

Hello, Zhih-Peng: If mydriatic agents are used and myopia still persists, it indicates true myopia rather than pseudomyopia, making it difficult for the refractive error to regress.
Mydriatic agents are used to prevent further progression of myopia.
Due to the dilation of the pupils, it is essential to wear glasses for protection against excessive light and ultraviolet rays.

Managing myopia (nearsightedness) and maintaining overall vision health is crucial, especially for individuals who have been diagnosed with varying degrees of refractive errors. Here are some effective eye care tips and insights based on your situation and general ophthalmological knowledge.
Understanding Myopia and Treatment Options
Myopia occurs when the eye is longer than normal or has a cornea that is too curved, causing distant objects to appear blurry. The use of dilating drops, such as those you mentioned, is often part of a comprehensive eye examination. These drops help the eye care professional assess the retina and optic nerve more effectively. While they do not directly treat myopia, they can help monitor eye health and detect any potential issues early on.
Eye Care Tips for Myopia Management
1. Regular Eye Exams: Continue your routine of semi-annual eye exams. Regular check-ups allow your eye care provider to monitor changes in your vision and adjust prescriptions as necessary.
2. Corrective Lenses: Ensure that you are using the correct prescription for your glasses or contact lenses. If you experience discomfort or blurred vision, consult your optometrist to reassess your prescription.
3. Limit Screen Time: The 20-20-20 rule is a helpful guideline: every 20 minutes, take a 20-second break to look at something 20 feet away. This practice can reduce eye strain from prolonged screen time.
4. Proper Lighting: Ensure that your reading and working areas are well-lit. Poor lighting can cause eye strain and discomfort, especially when reading or working on screens.
5. Outdoor Activities: Studies suggest that spending time outdoors may help slow the progression of myopia in children and adolescents. If possible, incorporate outdoor activities into your daily routine.
6. Eye Exercises: While there is limited scientific evidence supporting eye exercises for myopia, some people find that focusing on distant objects can help alleviate eye strain.
7. Healthy Diet: A diet rich in vitamins A, C, and E, as well as omega-3 fatty acids, can support eye health. Foods like carrots, leafy greens, fish, and nuts are beneficial.
8. UV Protection: Wearing sunglasses that block 100% of UVA and UVB rays is essential for protecting your eyes from harmful ultraviolet light, which can contribute to cataracts and other eye conditions.
9. Contact Lens Care: If you wear contact lenses, ensure you follow proper hygiene and care instructions. This includes cleaning and storing lenses correctly to prevent infections.
The Role of Dilation Drops
Dilation drops can help in assessing the health of the retina and optic nerve, but they do not directly affect myopia progression. They allow for a thorough examination of the eye's internal structures. If your eye care provider has recommended them, it is likely for monitoring purposes rather than treatment.
Conclusion
In summary, while dilation drops are useful for monitoring eye health, they do not treat myopia directly. Maintaining regular eye exams, using the correct prescription, managing screen time, and protecting your eyes from UV light are all vital components of effective eye care. If you have concerns about your vision or the effectiveness of your current treatment plan, do not hesitate to discuss these with your eye care provider. They can offer personalized advice and adjustments based on your specific needs and circumstances.
