Inquiry Consultation

Dear Dr.
Gao,
Thank you very much for your response to my personal inquiries; I have truly benefited from your insights.
This time, due to the delamination of my eyeglass lenses, I have come to understand many ophthalmological concepts that I previously only partially grasped or misunderstood.
I appreciate your willingness to address the public's questions through this platform.
I have the following questions for you:
1.
If the delamination of eyeglass lenses is not addressed and the lenses continue to be worn, what effects or symptoms might this have on the eyes or the body?
2.
Does wearing glasses with insufficient or excessive prescription affect the wearer's intraocular pressure? Is there a correlation between the two?
3.
For adults around the age of 40, what negative effects might occur if the eyeglass prescription is insufficient (i.e., weaker than the actual prescription)? For example, could this lead to an increase in myopia or other eye diseases?
4.
Is there an adaptation period for newly prescribed glasses? Some say that properly fitting glasses should not require any adjustment period and should not cause discomfort; however, others claim that new glasses always come with an adaptation period, which can last from three days to over a week.
Which perspective is accurate?
5.
Following the above, after wearing my new glasses (only the lenses were changed, with the right lens increased by +25 diopters, and I am unsure if there was any adjustment to the astigmatism), I experienced slight discomfort and a feeling of pressure near my right eye and temple after wearing them for about a day.
In your opinion, is this discomfort a normal part of the adaptation period, or does it indicate that the lenses are truly unsuitable?
6.
Additionally, prior to changing my lenses, I had an eye exam that resulted in a prescription of +25 diopters for the right lens (with other values seemingly unchanged).
However, I experienced some discomfort after wearing the new lenses, while the old lenses did not cause any discomfort.
I would like to ask if it is appropriate for me to request the optical shop to use the values from my previous lenses to replace the new ones.
Thank you again, Dr.
Gao.

Hello, Ah-Hsiang:

2.

3.
No, it won't happen.
4.
Yes, the eyes can get used to new glasses; there may be a transition period, which can vary from person to person.
5.
It may not necessarily be caused by the prescription.
Sometimes, an incorrect pupillary distance can also contribute.
However, new glasses might also cause such sensations.
6.
If discomfort persists, it may be better to use the original prescription.

More Info

Hello! Thank you for your thoughtful questions regarding eyewear concerns, particularly in relation to lens issues and prescription accuracy. I appreciate your proactive approach to understanding your eye health better. Let's address your questions one by one.

1. Effects of Lens Delamination: If you continue to wear glasses with delaminated lenses, it can lead to several issues. The primary concern is that the optical quality of the lenses is compromised, which may cause visual distortions, blurriness, or glare. This can lead to eye strain, headaches, and discomfort, especially during prolonged use. Over time, the stress on your eyes can contribute to fatigue and may exacerbate any underlying vision problems.

2. Impact of Incorrect Prescription on Eye Pressure: Wearing glasses with an incorrect prescription—whether too weak or too strong—does not directly affect intraocular pressure (IOP). However, if the incorrect prescription leads to significant eye strain or discomfort, it may indirectly influence your perception of pressure or discomfort in the eyes. It’s essential to have an accurate prescription to ensure optimal visual comfort and to avoid unnecessary strain.

3. Consequences of Under-Prescribing: For adults around the age of 40, wearing glasses with an under-prescribed lens (i.e., weaker than needed) can lead to several issues. While it may not directly cause an increase in myopia, it can lead to visual discomfort, eye fatigue, and headaches. Over time, if the eyes are consistently strained to see clearly, it may contribute to a decline in overall visual acuity. Additionally, prolonged strain can lead to conditions such as digital eye strain or even exacerbate presbyopia, which is common in this age group.

4. Adjustment Period for New Glasses: The concept of an adjustment period for new glasses is indeed valid. While some individuals may adapt quickly to their new lenses, others may experience discomfort for a few days to a week. This adjustment period can be influenced by factors such as the type of lenses (single vision, bifocal, progressive), the degree of prescription change, and individual sensitivity. If discomfort persists beyond a week, it may indicate that the prescription or fit is not correct.

5. Discomfort After Switching Lenses: Experiencing discomfort, such as soreness around the temples or eyes after wearing new glasses, can be a sign of several issues. It could be a normal part of the adjustment period, especially if there was a significant change in prescription. However, if the discomfort is pronounced or lasts longer than expected, it may indicate that the new lenses are not suitable for your vision needs. It’s important to monitor this and consult with your optometrist if the discomfort continues.

6. Reverting to Previous Prescription: If you find that your new lenses are causing discomfort and you had no issues with your previous prescription, it is reasonable to request that the optical shop create new lenses based on your old prescription. It’s crucial that you feel comfortable and can see clearly with your eyewear. Communicating your concerns with the optician can help ensure that you receive the best possible solution for your vision needs.

In conclusion, maintaining clear and comfortable vision is essential for your overall well-being. If you continue to experience discomfort or have concerns about your eyewear, I encourage you to follow up with your eye care professional. They can provide personalized advice and adjustments to ensure your glasses meet your visual needs effectively. Thank you for your questions, and I hope this information helps clarify your concerns!
