The final thickness of a pair of glasses, if you can choose an ideal frame, basically solves half of the problem. You can consider the appropriate cheapest eyeglasses frame size as the foundation, everything else is built on this foundation, and the foundation is of utmost importance.
If you care about thickness, you should at least choose the cheapest eyeglasses frame that matches the size first. You can consider putting everything else aside for now, after all, this pair of glasses will accompany you every day and night, except for sleeping.
If the gap between the frame width, center beam, and pupil distance can be reduced, then it can be made thinner. Finally, if cuts a little edge, the effect will be much better.
You can see that the gap between the frame width and pupil distance has been reduced, and the edge thickness has decreased, resulting in a significant reduction.
If you have high astigmatism, you also need to pay attention to the shape of the lens. If the astigmatism axis is at a 180-degree angle, try to choose a flat frame with a narrower upper and lower angle. On the contrary, if the astigmatism axis is at 90 degrees, try to choose a frame with a narrower lens width, which can reduce a lot of weight and edge thickness.
Try to choose the cheapest eyeglasses frame with a high pupil point close to the geometric center of the frame, so that the upward and downward movement of the lens is less, which can avoid water droplet-shaped lenses.
Otherwise, the height of the lens will make the lower edge very thick, and the pupil height will be too high, which will cause deformation and depression when viewed up close, and also greatly affect vision.
