Struggling with New Glasses: Headaches and Vision Issues Explained - Ophthalmology

I recently got new glasses, but I'm experiencing dizziness when wearing them. Please help, thank you?

---

I have been wearing glasses for over ten years, and my eyesight has progressed into the high myopia category.
I have changed more than ten pairs of glasses, including glass, plastic, spherical, and aspherical lenses.
I always go to the same ophthalmology clinic (because I feel comfortable and have never experienced any discomfort).
Currently, my myopia and astigmatism measurements are as follows: right eye - 850, 2.25*180; left eye - 775, 2.25*175.
Due to long-term glasses wear, I have separated my glasses into those for near vision (with a lighter prescription) and those for distance vision (with a full prescription).
The two pairs of aspherical plastic lenses have been worn for over five years, and the lens coating has deteriorated significantly.
In mid-May, I decided to replace the lenses for both pairs since the frames were still usable.
However, trouble arose! The two new pairs of glasses caused dizziness upon wearing.
Let me explain the situation for each pair of glasses separately:
1.
Distance Vision Glasses (full prescription, spherical glass lenses): When fitting the new distance vision lenses, the staff at the clinic mentioned that my current prescription is the same as five years ago, and that my myopia and astigmatism have stabilized.
Since I was not changing the frames, they suggested using the old prescription data for the lenses.
I agreed, and for durability, I switched from aspherical plastic lenses to spherical glass lenses (Vision HENG WMT HI).
A week later, when the new lenses arrived, I tried them on and immediately felt dizzy.
I informed the staff, who discovered that the focal length was incorrect and adjusted the frame's temple to the left.
The staff explained that this adjustment was necessary to align the lens focal length with my eyes.
They also mentioned that if I needed to remake the lenses, due to my high myopia, the new lenses would end up being uneven in thickness, with one side thin and the other thick, leading to an imbalance in weight.
After hearing this, I was skeptical but decided to try wearing the misaligned glasses.
Initially, there was some improvement, but within five minutes, the dizziness returned.
I informed the staff again, and they suggested that my dizziness might be caused by switching from aspherical to spherical lenses.
They noted that no one makes glass aspherical lenses anymore and advised me to try wearing the new lenses for a month and report back if there were issues.
If it didn’t work out, I would have to switch back to aspherical plastic lenses.
Now, after wearing them for over a month, the dizziness has somewhat improved, but new problems have arisen:
1.
My eyes feel strained; when I take off the glasses, I immediately feel a relaxation of the muscles around my eyes.
2.
When I use these glasses to read a book or newspaper for 1-2 minutes and then look at a clock five meters away, I find it difficult to see the three-centimeter numbers clearly.
My eyes need time to refocus before I can see them clearly.
3.
If the frame shifts or moves, I immediately feel dizzy.
4.
The glass lenses are heavy, leaving marks from the nose pads on my nose.
After wearing them for a month, I still have issues.
What should I do? According to the staff, no one makes aspherical glass lenses anymore, and remaking spherical glass lenses would result in one side being thin and the other thick.
Is this true? My eyes have become accustomed to aspherical lenses, so will I only be able to get plastic aspherical lenses in the future? The glass lenses cost 2500, but as they mentioned, switching to aspherical plastic lenses (Hoya) would cost 4950, which is a significant price difference.
Is this accurate?
2.
Near Vision Glasses (lighter prescription, spherical plastic lenses): Since these glasses are for indoor use, they are less prone to wear and tear, so I opted for spherical plastic lenses, which are cheaper.
The staff mentioned that for near vision, both eyes should have their prescriptions reduced by 150 degrees.
I agreed to this, but then the problems arose:
1.
Upon trying on the new glasses, I noticed that my left eye was noticeably blurrier, and there was a difference in clarity between my two eyes.
When I informed the staff, they replied that I could not simply increase the prescription for the left eye because it was blurrier.
Both eyes must maintain the same reduced prescription of 150 degrees.
If I wanted to increase the left eye's prescription, the right eye's actual prescription would also need to be increased.
In simple terms, the right eye is reduced by 150, and the left eye must also be reduced by 150; it cannot be right eye reduced by 150 and left eye reduced by 100.
Is there really such a regulation? What should I do about the blurriness in my left eye?
2.
I never expected that these near vision glasses would also cause dizziness.
When I informed the staff, they said this was due to my temporary inability to adapt to the spherical lenses, similar to the issue with my distance vision glasses.
They advised me to wear them for a month and report back if there were any problems.
If it still didn’t work, I would have to switch back to aspherical plastic lenses.
Now, after wearing the near vision glasses for over a month, my left eye is still noticeably blurrier, and I still experience dizziness! Both pairs of glasses cause dizziness, which is incredibly frustrating.
It feels like I spent over three thousand dollars only to suffer.
If I switch to aspherical plastic lenses as they suggested, the total cost for both pairs of lenses would be over nine thousand, not including the frames.
The price difference is significant.
If glass lenses are only available in spherical form, and if what they say is true that my eyes will reject spherical lenses, will I only be able to get the more expensive and less durable plastic aspherical lenses in the future? It feels like I am being forced to buy the most expensive products step by step.
What should I do? I kindly request assistance from professional doctors.
Thank you in advance!
