Pseudomyopia: Questions on Prescription and Eye Care - Ophthalmology

Prescription lens degree issues?


Hello Doctor, I am the person who previously inquired about the prescription glasses issue #188870.

1.
I would like to ask if, as you mentioned, the increase in pseudomyopia is not resolved, will it eventually turn into true myopia?
2.
Additionally, what methods are available for adults to reduce pseudomyopia? Or is it not possible to reduce it?
3.
If I need to look at close objects like my phone or computer, can I get another pair of glasses with the previously measured prescription of -6.75 diopters? Then, I would use the -8.75 diopter glasses for distance vision.
Would this affect my eyes? Could it potentially cause my prescription to increase? Yesterday, the ophthalmologist only said that as long as I can see well, it’s fine, and did not answer my questions about which prescription would be more suitable, leaving me quite confused.

Also, the doctor prescribed artificial tears yesterday, and after using them this morning, I felt some itchiness in my eyes.
However, I did not use them at noon, and the itchiness near the inner corner of my eyes persists.
Should I continue using the artificial tears and antihistamine drops? I felt a stinging sensation after applying them; is that a concern? Should I refrain from using them for now? Thank you, Doctor, for your assistance.

Hello: 1.
No, it may be due to the use of a dilating agent, which can temporarily lower the prescription.
Please refer to: https://bit.ly/30ou9SH 2.
Same as above.
3.
You can do so, but it is best to use the actual prescription after dilation for distance vision.
It may be unclear at first, but you will gradually get used to relaxing your eyes, and it will become clearer.
For computer use, reduce the prescription by about 100 degrees to avoid excessive eye strain.
You can continue using the drops until there is no itching.

Understanding pseudomyopia and its implications for eye care is essential, especially for individuals experiencing vision changes. Pseudomyopia, often referred to as "false myopia," occurs when the eye's focusing system is overly strained, leading to temporary nearsightedness. This condition can be particularly concerning for those who spend extended periods on near tasks, such as using computers or smartphones.
1. Pseudomyopia vs. True Myopia: If the pseudomyopia does not resolve, it can potentially lead to true myopia. This transition occurs when the eye's elongation becomes permanent due to prolonged stress on the eye's focusing muscles. Therefore, it is crucial to address the underlying causes of pseudomyopia, such as reducing screen time, taking regular breaks, and ensuring proper lighting while reading or using devices.

2. Managing Pseudomyopia in Adults: For adults, managing pseudomyopia involves several strategies. Regular eye examinations are essential to monitor changes in vision. Eye exercises, such as the 20-20-20 rule (every 20 minutes, look at something 20 feet away for at least 20 seconds), can help alleviate strain. Additionally, ensuring proper ergonomics while using screens—such as maintaining an appropriate distance and angle—can reduce the risk of developing true myopia. In some cases, the use of corrective lenses specifically designed for near tasks may be beneficial.

3. Using Different Prescription Glasses: It is possible to have different prescriptions for various tasks. If you have a pair of glasses with a prescription of 675 degrees for near vision and another pair of 875 degrees for distance, using them appropriately should not negatively impact your eyes. However, switching between prescriptions frequently can cause temporary discomfort as your eyes adjust. It is essential to ensure that the prescriptions are accurate and that you are using the correct pair for the intended task. If you find that your vision is still unclear or if you experience discomfort, it may be worth discussing with your eye care professional to ensure that your prescriptions are appropriate.

4. Eye Drops and Discomfort: Regarding the use of eye drops, it is not uncommon to experience some initial irritation or a stinging sensation when using new eye drops. This can be due to the preservatives in the drops or the formulation itself. If the discomfort persists or worsens, it is advisable to consult your eye care provider. They may recommend a preservative-free alternative or suggest a different treatment approach. If you are experiencing itching or discomfort in the corners of your eyes, it may be beneficial to continue using the prescribed drops, but monitor your symptoms closely. If the irritation does not improve, or if you have concerns about the drops, do not hesitate to reach out to your healthcare provider for further guidance.

In summary, understanding the nuances of pseudomyopia and its management is crucial for maintaining optimal eye health. Regular check-ups, appropriate use of corrective lenses, and proper eye care practices can significantly impact your vision and overall eye comfort. If you have any further questions or concerns, please consult with your eye care professional for personalized advice tailored to your specific situation.
