Eye Discomfort: Is Your Prescription Causing Dryness and Pain? - Ophthalmology

Eyeglass issues?


Hello Doctor, I got my first pair of glasses at the age of 20 (I am currently 23), which included a prism.
When I first wore them, my eyes felt dry and painful.
After wearing them for a month, there was still no improvement.
The optical shop told me, "Since you have never worn glasses before and have always relied on your right eye, your left eye has hardly been used." They advised me to continue adapting to the glasses.
However, after almost two years, I still experience dryness after wearing the glasses for a few hours (taking them off does not cause dryness).

I would like to ask you, Doctor, whether this situation indicates that the glasses were not prescribed correctly, or if such a long adaptation period is truly necessary.
The reason I am inquiring is that I recently went to another optical shop to get new glasses and discovered that the prescription of my first pair had random variations of 0.25 to 0.5 diopters, indicating an uneven prescription.
The new optical shop informed me that wearing lenses with uneven prescriptions for an extended period could lead to problems.

So, I would like to know if the dryness and pain I experience while wearing glasses, as well as the prolonged adaptation period, could be related to the uneven prescription.
Thank you.

It is recommended that you visit an ophthalmology clinic for consultation to determine if any relevant examinations are necessary.
Thank you, and wish you good health!

Understanding eye discomfort, particularly when it comes to wearing glasses, can be a complex issue that involves several factors. Based on your description, it seems that you have been experiencing dryness and pain while wearing your glasses, which has persisted for nearly two years. This situation raises several important considerations regarding your prescription, the fit of your glasses, and your overall eye health.

Firstly, it is essential to understand that when you first start wearing glasses, especially if you have never worn them before, your eyes may need time to adjust. This adjustment period can vary from person to person, but typically, it should not last for an extended period like two years. If you are still experiencing discomfort after such a long time, it may indicate that there is an underlying issue with your prescription or the fit of your glasses.

You mentioned that your first pair of glasses included a prism correction. Prism lenses are designed to help with eye alignment issues, but they can also cause discomfort if not prescribed correctly. If the prism is not accurately calculated for your specific needs, it can lead to visual strain, which may manifest as dryness and pain. Additionally, if you have been primarily using one eye (your right eye) and neglecting the other (your left eye), this could lead to an imbalance in how your eyes work together, further contributing to discomfort.

The issue of your glasses having uneven prescription strengths (ranging from 0.25 to 0.5) is also significant. Inconsistent lens power can lead to visual distortion and strain, making it difficult for your eyes to focus properly. This can result in symptoms such as dryness, fatigue, and pain. It is crucial to have a precise and accurate prescription to ensure that both lenses work harmoniously to provide clear vision without causing discomfort.

Moreover, the sensation of dryness when wearing glasses could also be related to how your eyes are functioning. If your eyes are not producing enough tears or if there is an issue with the quality of your tears, this can lead to dryness, especially when wearing corrective lenses. Contact lenses can sometimes exacerbate this issue, but it can also occur with glasses if your eyes are not adequately lubricated.

To address your concerns, I recommend the following steps:
1. Consult an Eye Care Professional: Schedule an appointment with an optometrist or ophthalmologist to have your eyes thoroughly examined. They can assess your current prescription, check for any underlying eye conditions, and ensure that your glasses are correctly fitted.

2. Discuss Your Symptoms: Be open about your experiences with dryness and pain. This information will help your eye care provider understand your situation better and make appropriate recommendations.

3. Consider a New Prescription: If your current glasses are causing discomfort, it may be time to get a new prescription. Ensure that the new lenses are made with precise measurements to avoid any inconsistencies.

4. Explore Eye Drops: If dryness is a persistent issue, consider using artificial tears or lubricating eye drops to help alleviate discomfort. These can provide relief and improve your overall comfort while wearing glasses.

5. Evaluate Your Wearing Habits: If you find that your eyes are more comfortable without glasses, it may be worth discussing alternatives, such as contact lenses or even refractive surgery, depending on your eye health and lifestyle.

In conclusion, while some initial discomfort when wearing glasses is normal, prolonged symptoms like dryness and pain are not. It is crucial to address these issues with a qualified eye care professional to ensure that your prescription is accurate and that your glasses are suitable for your needs. Taking these steps can help improve your comfort and overall eye health.
