When it comes to managing your vision, especially with your current prescription of 75 degrees in your left eye and 200 degrees in your right eye, there are several factors to consider regarding the use of glasses and the impact of prolonged reading or screen time.

1. Wearing Glasses Only While Studying: Your concern about whether not wearing glasses during daily activities will worsen your vision is valid. Generally, if you have a refractive error (like myopia or hyperopia), not wearing glasses during activities where you need clear vision (like walking or playing sports) will not directly worsen your prescription. However, it is important to note that if you strain your eyes frequently by not wearing corrective lenses when needed, it can lead to eye fatigue and discomfort. This discomfort might make you feel like your vision is worsening, but it doesn't necessarily mean that your actual prescription is increasing.
2. Impact of Long Study Hours: Regarding your study habits, it is true that prolonged periods of reading or screen time can contribute to eye strain and potentially lead to an increase in myopia over time. The recommendation of taking breaks, such as studying for 30 minutes and then resting for 10 minutes, is a good practice. This technique, often referred to as the 20-20-20 rule, suggests that every 20 minutes, you should look at something 20 feet away for at least 20 seconds. This helps reduce eye strain and can be beneficial in preventing further deterioration of your vision.

3. Age Factor: At 23 years old, your eyes are likely to be more stable compared to younger individuals whose eyes are still developing. Your eye doctor’s advice that your vision may not worsen significantly from not wearing glasses during non-visual tasks is generally accurate. However, the cumulative effect of prolonged near work without proper breaks can still contribute to changes in your vision over time.

4. General Recommendations: To maintain your eye health, consider the following:
- Use Corrective Lenses: Wear your glasses whenever you are engaging in activities that require clear vision, including walking, driving, or playing sports. This will help reduce eye strain.

- Take Regular Breaks: Implement the 20-20-20 rule to give your eyes a chance to relax.

- Maintain Proper Lighting: Ensure that your study area is well-lit to reduce strain on your eyes.

- Stay Hydrated and Maintain a Healthy Diet: Proper hydration and nutrition can support overall eye health.

5. Consulting an Eye Care Professional: If you notice any significant changes in your vision or if you have ongoing concerns about your eye health, it is advisable to consult with an eye care professional. Regular eye exams can help monitor your vision and ensure that any necessary adjustments to your prescription are made in a timely manner.

In conclusion, while not wearing glasses during certain activities may not directly worsen your vision, it is essential to practice good eye care habits, especially with the amount of time you spend studying. Taking breaks, using your glasses appropriately, and maintaining a healthy lifestyle will all contribute to better eye health and potentially slow the progression of any refractive errors.
