When it comes to understanding prescription changes for eyeglasses, it's important to consider several factors that can influence your vision and comfort. Here’s a comprehensive breakdown of your questions and concerns.

1. Should You Switch Back to Old Glasses?
If you've recently received a new pair of glasses and are experiencing discomfort, such as dizziness or blurriness, it may be wise to revert to your old glasses temporarily. This can help you determine if the new prescription is the cause of your discomfort. It's not uncommon for individuals to take some time to adjust to a new prescription, especially if there has been a significant change in the lens power. However, if the discomfort persists beyond a few days, or if you feel that your vision is worse than with your old glasses, it’s advisable to consult with your optometrist. They can assess whether the prescription is appropriate or if further adjustments are necessary.

2. Does Wearing Glasses with a Prescription Too Close to Your Current Needs Cause Myopia to Worsen?
The concern that wearing glasses with a prescription that is too close to your current needs can worsen myopia (nearsightedness) is a common belief. However, the relationship between glasses prescriptions and the progression of myopia is complex. While wearing an incorrect prescription can lead to eye strain and discomfort, it does not directly cause myopia to worsen. Myopia progression is influenced by various factors, including genetics, environmental factors, and visual habits. That said, wearing the correct prescription is essential for optimal visual comfort and to prevent unnecessary strain on your eyes.

3. Are There Effective Exercises to Reduce Prescription Strength?
The idea of exercises to reduce the strength of your glasses prescription is a topic of debate. While some proponents of vision therapy suggest that certain exercises can help improve visual function, there is limited scientific evidence to support the claim that these exercises can significantly reduce myopia or the need for corrective lenses. Common exercises include focusing on distant objects, eye rolling, and practicing relaxation techniques. However, these should not replace regular eye exams or the use of prescribed corrective lenses. If you are interested in exploring vision therapy, it’s best to consult with an eye care professional who specializes in this area.

In summary, if you are experiencing discomfort with your new glasses, it’s reasonable to switch back to your old pair until you can consult with your optometrist. They can provide guidance on whether your new prescription is appropriate and discuss any potential adjustments. Additionally, while the idea of exercises to reduce myopia is appealing, it’s crucial to approach such claims with caution and rely on professional advice for managing your vision health. Regular eye exams and following your eye care provider's recommendations are the best ways to ensure your vision remains stable and comfortable.
