Presbyopia/Prescription Glasses Issues

Hello, Doctor: I have been wearing stress-relief lenses for over two years.
For distance vision: Right eye: myopia -800, astigmatism -400.
Left eye: myopia -725, astigmatism -350.
The lower section is said to be presbyopia, so the prescription seems to be about 100 degrees less (since I need to look at a computer for more than 10 hours a day).
However, after getting the lenses, I can see the text on the computer, but it still feels a bit blurry.
The optician mentioned it might be due to distance.
Since presbyopia changes every 10 centimeters, they can only adjust based on the distance from the computer to my eyes, but I feel that whether I sit close or far, the result is the same and I cannot achieve clarity.
1.
I would like to ask the doctor, given my situation, is it very difficult to see clearly up close, and will it always be somewhat blurry? Currently, my distance vision does not feel very clear, and I am unsure if it is due to poor eye accommodation.
After the eye exam, it was noted that the prescription for my left eye has not changed, while the right eye has increased by 75 degrees.
The optician suggested that if I get two pairs of glasses: for near vision, I should reduce the left eye by 75 degrees, and for distance, just adjust the right eye accordingly.
I have no doubts about the distance vision, but I was never clear for near vision either.
2.
I would like to ask the doctor, if the left eye is reduced, will it only make near vision more comfortable, but not necessarily improve clarity?
3.
The optician mentioned that I could get multifocal lenses, but since I am already struggling with the stress-relief lenses, would getting multifocal lenses make it even harder for me to adjust? Additionally, a previous doctor mentioned that the brain automatically chooses the eye with better vision to see things, which is normal.
4.
Therefore, I would like to ask the doctor, does this mean that for distance vision, I tend to use my left eye, and for near vision, I use my right eye? So, is it actually unnecessary to get new glasses? Thank you, Doctor, for taking the time to respond.

Hello: 1.
Regarding the clarity issue with myopia, even with stress-relief lenses, one may still experience blurriness due to presbyopia and accommodation problems.
For prolonged computer use, it is recommended to use computer-specific glasses or multifocal lenses to enhance clarity.
Additionally, an adaptation period may be necessary.
2.
Considering your situation, adjusting the prescription for your left eye may provide more comfort when viewing nearby objects, but it may not significantly improve clarity.
Overall, multifocal lenses could be a viable option.
3.
Wearing multifocal lenses may indeed require some adaptation time; it is advisable to closely monitor your visual experience during this period, and if discomfort arises, consult an ophthalmologist promptly.
4.
The brain's automatic preference for the eye with better vision is a normal physiological response.
However, using one eye for distance and the other for near vision, while a compromise, is not as effective as having both eyes able to see clearly at all distances simultaneously, and it may require an adjustment period and can lead to discomfort.

Hello! Thank you for your detailed questions regarding your vision and the challenges you're facing with your current prescription glasses. Let's address each of your concerns systematically.

1. Clarity of Near Vision: Given your prescription of -800 and -725 for distance vision, along with significant astigmatism, it is understandable that you might struggle with clarity when looking at close objects, especially after prolonged computer use. The fact that you are experiencing a persistent blur suggests that your current glasses may not be adequately compensating for your presbyopia, which is common as we age. The adjustment of -100 degrees for near vision is a standard approach, but if you still find it difficult to see clearly at your working distance, it may be necessary to reassess your prescription. It’s crucial to ensure that the glasses are tailored to your specific working distance, which can vary depending on your setup.

2. Adjusting the Left Eye Prescription: Lowering the prescription for your left eye by 75 degrees may provide some comfort for near tasks, but it might not significantly enhance clarity if the underlying issue is related to the overall prescription or the lens design. If your left eye is not providing clear vision at near distances, simply reducing the power may not resolve the issue. It’s essential to have a comprehensive eye exam to determine if your left eye needs a different approach or if other factors are contributing to the blurriness.

3. Multifocal Lenses: Transitioning to multifocal lenses could be beneficial, especially if you are struggling with both distance and near vision. However, it’s important to note that multifocal lenses require an adjustment period as your brain learns to switch between different focal points. If you have difficulty with your current lenses, it may take some time to adapt to multifocal lenses, but many patients find them to be a worthwhile investment for improved overall vision. If you are concerned about managing the transition, consider discussing your specific needs with your optometrist, who can provide tailored advice.

4. Eye Preference for Vision: It is indeed true that the brain tends to favor the eye that provides clearer vision. If you find that your left eye is better for distance and your right eye for near tasks, this could be a natural adaptation. However, this does not necessarily mean you should avoid getting new glasses. If your current prescription does not provide satisfactory clarity for both near and far distances, it may be worthwhile to explore new options. Your optometrist can help determine if a new prescription or lens type is necessary based on your visual needs.

In summary, it seems that your current glasses may not be adequately addressing your vision needs, particularly for prolonged computer use. A comprehensive eye exam is recommended to reassess your prescription, and discussing the possibility of multifocal lenses could provide a solution that allows for clearer vision at all distances. Remember that vision changes can be gradual, and it’s essential to stay proactive about your eye care. If you have further questions or concerns, don’t hesitate to reach out to your eye care professional for personalized advice.
