Normal cheap eyeglasses near me frame should have a consistent forward tilt angle, with the front and back sides placed, both legs on the ground, and the legs folded together to overlap. Pay attention to the front-to-back order, which includes the forward tilt angle, pile head, mirror legs, and foot covers.

The normal curvature of the cheap eyeglasses near my frame should be straight or slightly curved inward. 0-6 degrees are commonly considered normal.

If you wear a glasses frame with abnormal curvature for a long time, after getting used to it for a long time, the next pair of glasses often inexplicably does not adapt. It can also cause the legs of both glasses to expand outward, making it easy for the glasses to slide down. Method: The metal mirror frame is directly broken (method as above), and the plate must be heated before breaking.

The cheap eyeglasses near my nose pad must adhere to the nose to the maximum extent possible to minimize "pressure" (as physics calls it). The ideal state should be to place the double support leaves on the bridge of the nose bone (feel the hard part of your nose, that's it).

If it doesn't fit properly, there are specialized pointed tools available. It's best not to adjust the nose pads by yourself. This requires real skills to adjust. Here is also a note: nose pads can only be adjusted if the forward tilt angle is consistent. Otherwise, it is very likely that no matter how you adjust it, you cannot adjust the nose pad properly.

The amplitude of the two eyeglasses' legs should be the same, otherwise, the force will be uneven, causing one lens to stick to the face and the other to move away from the face. You can choose to tighten or loosen the legs with a larger expansion range, depending on whether the frame is loose or tight. If the tension is appropriate, you can loosen it while tightening it.
