The confusion regarding the use of magnifying glasses with myopia glasses and reading glasses?
Hello, doctor.
I have a prescription of L-175 and R-125, and I experience blurriness when looking at distant objects.
I have already obtained glasses for my myopia.
1.
I need to use my eyes for close work due to my job, and I can see clearly up close.
To avoid straining my eyes, can I wear my myopia glasses while using a magnifying glass, or should I not use both at the same time?
2.
I would like to get reading glasses.
An optometrist suggested that I should reduce my current prescription for the reading glasses.
Based on my prescription, he recommended L-100 and R-25 for the reading glasses.
I would like to ask you, doctor, whether the prescription for reading glasses should be based on the reduced values or should it be adjusted upwards?
Thank you for taking the time to answer my questions.
I really appreciate it.

It has become clear that a magnifying glass may not be necessary.
The need for corrective lenses depends on age and individual circumstances.

Hello! Thank you for your detailed questions regarding your vision and the use of reading glasses in conjunction with your myopia. Let's break down your concerns and provide some insights based on your situation.
1. Using Myopia Glasses with a Magnifying Glass: It is generally possible to wear your myopia glasses while using a magnifying glass. However, the effectiveness of this combination can depend on several factors, including the strength of your glasses and the magnifying glass. When you wear myopia glasses, they are designed to correct your distance vision, and if you are using them for close work, they may not provide the optimal clarity you need. The magnifying glass can help enhance your ability to see small text or details up close, but it may also introduce some distortion or additional strain if not used correctly. Therefore, it is advisable to experiment with both together to see how your vision responds. If you find that using both together causes discomfort or strain, it might be worth consulting with your optometrist for personalized advice.
2. Choosing the Right Prescription for Reading Glasses: When it comes to selecting the prescription for reading glasses, the approach can vary based on individual needs. The suggestion from your optometrist to reduce your existing prescription for reading glasses is a common practice. This is because reading glasses are typically designed to provide a comfortable focal distance for reading, which is usually closer than the distance at which your distance glasses are optimized.
In your case, with your current prescriptions of L-175 and R-125, the optometrist's recommendation of L-100 and R-25 for reading glasses seems to be aimed at providing you with a more comfortable reading experience. The idea is to reduce the prescription to accommodate the closer distance of reading materials. However, it is essential to ensure that the new prescription allows you to read comfortably without straining your eyes.
If you are considering reading glasses, it is also worth discussing with your optometrist whether you might benefit from progressive lenses or bifocals, which can provide a seamless transition between different focal distances. This could be particularly useful if you frequently switch between reading and looking at objects at a distance.
Additional Considerations
- Eye Strain and Fatigue: Given your work requires prolonged near vision, it's crucial to take regular breaks to reduce eye strain. The 20-20-20 rule is a helpful guideline: every 20 minutes, look at something 20 feet away for at least 20 seconds. This practice can help alleviate discomfort and fatigue.
- Dry Eye Symptoms: If you experience any dryness or discomfort while reading, consider using artificial tears or lubricating eye drops to keep your eyes moist, especially if you are working in an environment with low humidity or prolonged screen time.
- Regular Eye Exams: Since your vision needs may change over time, regular check-ups with your optometrist are essential. They can monitor your vision and make necessary adjustments to your prescriptions as needed.
In conclusion, wearing myopia glasses while using a magnifying glass can be effective, and adjusting your reading glasses prescription to a lower strength is a common practice. Always consult with your optometrist for personalized recommendations based on your specific vision needs. Thank you for your questions, and I hope this information helps you navigate your vision care effectively!
