I suspect the discomfort when switching glasses is that the inter-ocular distance is different between the two glasses (one is likely right or "more right"). You have the right correction, but it is off-axis WRT your pupils with one pair.
When I go to my $$$ optician, the technician marks my pupils on the blanks in the frame that I've selected using a sharpie (before the glasses are made) and adds the inter-ocular measurement to the glasses information. When I put on the resulting glasses, I don't have any eye strain symptoms and my vision is good (instantly).
When I went to cheap storefront glasses places (I don't do that any more) and I put on the resulting glasses, I get a "stress" signal from my eyes and then they adjust to work with the suboptimal glasses but the eye strain is always there.
- AdrianB1 7y agoMy optician friend is doing the inter-ocular distance right, he showed me the process while he was cutting the lenses on a high-end computerized machine. But the only difference between my glasses are the frames, there are some differences in the frames that makes a difference in the final product. I guess it is the angle between the lenses, even a small difference can be creating the discomfort. It takes me a few hours to adjust.
