Glasses for myopia?
Hello, doctor.
I have a pair of glasses that I've been wearing for three years.
A few months ago, I got a new pair with a prescription that is about 100 degrees stronger in one eye.
Since I am an artist and often work at close distances, the doctor who prescribed my glasses recommended that I wear the new pair for over half an hour, but I have been alternating between the old and new pairs.
Yesterday, when I accompanied a friend to an optical shop, the owner tested my vision and expressed strong disapproval of my alternating use of the old and new glasses.
He said that this could easily lead to presbyopia.
Is this true? However, I find that wearing the new glasses for extended periods makes me uncomfortable when looking at things up close.
If I need to paint for over four hours, will my prescription worsen quickly? What should I do? Thank you for taking the time to read my question (*^^*).

Hello, Mr.
Cao: I recommend using lower prescription lenses for long periods of drawing, as this can help reduce fatigue and is less likely to lead to presbyopia.
The ophthalmology department at Puzi Hospital in Taiwan is open Monday to Friday from 8:00 AM to 12:00 PM and Wednesday afternoons from 1:00 PM to 4:30 PM.
Please note that online responses are for reference only; it is essential to seek medical attention at a healthcare facility if necessary.
I hope to have the opportunity to serve you.
Sincerely, Gao Pilin.

Managing myopia, especially for someone who engages in close-up work like painting, can be quite challenging. Your concerns about switching between old and new glasses, and the potential for developing presbyopia (often referred to as "old-age sight") are valid and deserve careful consideration.
Firstly, it’s important to understand that myopia, or nearsightedness, is a condition where distant objects appear blurry while close objects can be seen clearly. As you age, the eye's lens naturally loses flexibility, leading to presbyopia, which makes it difficult to focus on close objects. This is a normal part of aging and typically begins in the early to mid-40s. However, the use of different prescriptions for close-up work can complicate matters.
Switching between two different prescriptions can lead to visual discomfort. When you alternate between your old and new glasses, your eyes may struggle to adapt to the different focal points, which can cause eye strain, headaches, and fatigue. This is particularly true if the new prescription is significantly stronger for close work, as you mentioned. The discomfort you experience when wearing the new glasses for extended periods could be due to the increased prescription, which may not be optimized for your specific needs in art creation.
Regarding the concern about developing presbyopia, using glasses with a stronger prescription for close work does not directly cause presbyopia. However, if you are straining your eyes by using a prescription that is not suitable for your work, it can lead to discomfort and potentially accelerate the feeling of visual fatigue. It’s crucial to have the right prescription tailored for your specific activities, especially when engaging in tasks that require prolonged focus on close objects.
To address your situation, here are some recommendations:
1. Consult an Eye Care Professional: It’s essential to have a comprehensive eye exam with an optometrist or ophthalmologist who understands your specific needs as an artist. They can assess your current prescriptions and provide guidance on whether you need a different pair of glasses specifically for your art.
2. Consider Progressive Lenses: If you find yourself needing different prescriptions for various distances, progressive lenses might be a good option. These lenses provide a smooth transition between different focal points, allowing you to see clearly at all distances without the need to switch glasses.
3. Limit Eye Strain: When working for extended periods, 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 can help relax your eye muscles.
4. Proper Lighting: Ensure that your workspace is well-lit. Good lighting can reduce the strain on your eyes when working on detailed tasks like painting.
5. Monitor Your Vision: Keep track of any changes in your vision. If you notice significant changes or increased discomfort, return to your eye care professional for further evaluation.
6. Avoid Overuse of Old Glasses: While it may be tempting to rely on your old glasses for comfort, doing so can lead to further complications. It’s best to use the most appropriate prescription for your current needs.
In summary, while switching between different prescriptions can lead to discomfort, it does not directly cause presbyopia. However, ensuring that you have the right prescription for your artistic work is crucial. Regular consultations with your eye care provider will help you manage your myopia effectively and maintain your visual health as you continue your artistic endeavors.
