Should You Wear Glasses Constantly to Prevent Vision Deterioration? - Ophthalmology

When it comes to managing vision deterioration, particularly in the context of myopia (nearsightedness), the question of whether to wear glasses constantly is a common concern. The short answer is that wearing glasses as prescribed can help you see clearly, but the relationship between wearing glasses and the progression of myopia is more nuanced.


Understanding Myopia and Glasses
Myopia occurs when the eyeball is too long or the cornea is too curved, causing light rays to focus in front of the retina instead of directly on it. This results in distant objects appearing blurry while close objects can be seen clearly. The degree of myopia is measured in diopters, and as you mentioned, you have recently been prescribed glasses with a prescription of over 200 degrees.

Wearing glasses helps correct your vision, allowing you to see clearly at distances that would otherwise be blurry. This is particularly important in educational settings, such as classrooms, where seeing the blackboard is essential for learning.

Should You Wear Glasses Constantly?
1. Wearing Glasses for Clarity: If your glasses allow you to see clearly, especially for distance tasks like watching a lecture or driving, it is advisable to wear them when needed. This will not only improve your visual experience but also reduce eye strain that can occur from squinting or straining to see.

2. Impact on Myopia Progression: There is ongoing research regarding the impact of wearing glasses on the progression of myopia. Some studies suggest that wearing corrective lenses does not significantly influence the rate at which myopia worsens. However, it is essential to note that not wearing glasses when needed can lead to increased eye strain and discomfort, which may indirectly affect your overall eye health.

3. Constant Use vs. Intermittent Use: For individuals with myopia, especially those who are still in their formative years (like yourself at 24), it is generally recommended to wear glasses consistently for distance vision tasks. If you find that you are frequently straining your eyes or experiencing discomfort without your glasses, it may be beneficial to wear them more regularly.

4. Outdoor Activities: Engaging in outdoor activities is also crucial for eye health. Studies have shown that spending time outdoors can help slow the progression of myopia. This is thought to be due to increased exposure to natural light and the opportunity for your eyes to focus on distant objects, which can be beneficial for eye development.


Additional Considerations
- Regular Eye Exams: It is essential to have regular eye examinations to monitor your vision and adjust your prescription as necessary. This will help ensure that your glasses are providing the best possible correction for your vision.

- Eye Care Practices: In addition to wearing glasses, consider implementing good eye care practices. This includes taking regular breaks during prolonged near work (like studying or using a computer), practicing the 20-20-20 rule (every 20 minutes, look at something 20 feet away for 20 seconds), and ensuring proper lighting while reading or working.

- Discuss with an Eye Care Professional: If you have concerns about your vision or the progression of myopia, discussing these with an eye care professional can provide personalized advice and recommendations tailored to your specific situation.


Conclusion
In summary, wearing glasses as prescribed is important for clear vision and can help reduce eye strain. While the direct impact of wearing glasses on the progression of myopia is still being studied, it is generally advisable to wear them when needed, especially for distance vision tasks. Additionally, incorporating outdoor activities and maintaining good eye care practices can contribute positively to your overall eye health. Always consult with your eye care provider for personalized advice and regular check-ups.
