Hello! Thank you for your detailed questions regarding your eyeglass prescription changes and eye health concerns. Let's address each of your queries one by one.

1. Wearing Old Glasses: If you find that your old glasses (with a prescription of -3.00 diopters) allow you to see clearly for your usual activities like reading and using the computer, you may not need to switch to the new glasses (with a prescription of -4.00 diopters) immediately. However, it’s important to consider that your vision may not be optimal for distance viewing, which could lead to eye strain over time. If you experience discomfort or headaches after prolonged use of the old glasses, it might be beneficial to transition to the new prescription.

2. Alternating Between Two Pairs of Glasses: Alternating between two pairs of glasses with different prescriptions can be manageable, but it may lead to some visual discomfort initially as your eyes adjust to the different lens powers. This adjustment period can vary from person to person. However, it is unlikely to cause your prescription to worsen directly. The progression of myopia (nearsightedness) is influenced by factors such as genetics and visual habits rather than simply switching between glasses. It’s essential to monitor how your eyes feel when switching between the two pairs.

3. Choosing Between Old and New Glasses for Reading: Since your new glasses include prism correction for your right eye due to your exophoria (outward eye misalignment), it is generally advisable to wear the new glasses when engaging in activities like reading or using the computer. The prism helps align your eyes better, which can reduce eye strain and improve comfort during prolonged tasks. If you find that the new glasses provide clearer vision and reduce discomfort, they would be the better choice for your visual tasks.

4. Impact of Prism Lenses on Prescription: Wearing prism lenses does not inherently worsen your prescription. The purpose of the prism is to help with eye alignment and to alleviate symptoms associated with strabismus (eye misalignment). However, if you find that you are straining to see clearly with the new glasses, it could lead to discomfort, which might make you feel like your vision is deteriorating. It’s crucial to ensure that the new glasses are properly fitted and that the prescription is accurate. If you experience persistent discomfort or visual issues, it would be wise to consult your eye care professional for a follow-up.

In summary, while it’s okay to wear your old glasses if they provide clear vision for your daily tasks, transitioning to the new prescription, especially for activities requiring precise vision, is advisable. Monitoring how your eyes respond to the new glasses is essential, and if you have any concerns about discomfort or changes in your vision, don’t hesitate to reach out to your eye care provider. Regular eye exams and proper lens prescriptions are key to maintaining good eye health and ensuring that your vision remains stable.
