There must be something you think is right, but it's wrong. The height of the glasses frame is due to the nose support. It's caused by the height of the cheapest eyeglasses legs.

Wearing one lens far away and the other close is due to nose pads. The two legs of the eyeglasses have different external angles. Optometry data does not equal appropriate fitting data, and fitting is not just about the optometry process. If other aspects are not suitable, the glasses will still fail to be matched.

Nonspherical lenses are indeed better than spherical lenses, even if they are double-sided nonspherical, there may still be deformation around the edges. Good lenses only have less deformation.

Titanium is indeed a better material, but the quality of good alloy frames may still be much better than ordinary titanium frames. The weight composition of the cheapest eyeglasses is mainly composed of lenses, especially for high myopia.

From a long-term and health perspective, the long-term accumulation of blue light damage cannot be ruled out. In the short term and terms of comfort, blue light eyeglasses lenses do have a reducing effect on visual fatigue.

The myopia and astigmatism of the lens itself do not change, but the pupillary distance, pupil height, and astigmatism axis are likely to change. The new glasses are uncomfortable due to various possible reasons, such as high pupil height, stress, curvature, forward tilt angle, distance between the eyes, deformation of the frame, wearing posture, axial deviation, etc.

Anyone who lives long enough will age. It is a normal physiological phenomenon, characterized by a decrease in crystal elasticity and an increase in density, leading to a decline in regulatory function and difficulty in observation. You need to wear a lower degree of myopia to see up close.
