When it comes to the question of whether you should replace your glasses if your myopia (nearsightedness) decreases, there are several factors to consider. First and foremost, it's essential to understand that changes in your prescription can occur over time due to various reasons, including age, eye health, and lifestyle factors.
In your case, you mentioned that your right eye's prescription has decreased from 800 degrees to 700 degrees. This change is significant enough that it warrants consideration for a new pair of glasses or at least new lenses. Here are some points to consider:
1. Visual Clarity: If your current glasses are no longer providing the optimal clarity for your vision, it is advisable to get new lenses that match your updated prescription. Wearing glasses with an outdated prescription can lead to visual discomfort, eye strain, and headaches, especially if you spend long hours reading or using a computer.

2. Adaptation Period: If you decide to replace your lenses, be aware that there may be an adaptation period as your eyes adjust to the new prescription. This is particularly true if there is a significant difference in the prescription between your two eyes. Your brain will need time to reconcile the differences in visual input from each eye.

3. Daily Variability: It is true that your vision can fluctuate daily due to various factors such as fatigue, stress, or even hydration levels. However, if you consistently notice that your vision is clearer with the new prescription, it is a strong indicator that you should proceed with the change.
4. Consultation with an Eye Care Professional: It is always best to consult with your optometrist or ophthalmologist regarding your specific situation. They can provide personalized advice based on a comprehensive eye examination. If your vision fluctuates significantly, they may recommend monitoring your vision over a short period before making a decision on new lenses.

5. Impact on Eye Health: Wearing glasses that do not match your current prescription can potentially lead to further eye strain and discomfort. In some cases, it may even contribute to worsening vision over time. Therefore, ensuring that your glasses are up-to-date is crucial for maintaining good eye health.

6. Long-term Considerations: If your myopia continues to decrease, you may find yourself needing to update your prescription more frequently. This is not uncommon, especially in younger individuals whose eyes are still developing. Regular eye exams are essential to monitor these changes.

In summary, if your right eye's prescription has decreased, it is advisable to consider replacing your lenses to ensure optimal vision and comfort. While daily fluctuations in vision can occur, having the correct prescription will help mitigate discomfort and support your overall eye health. Always consult with your eye care professional to make the best decision for your specific needs.
