2. Lens eye distance, as the name implies, is the distance from the spectacle lens to the eye, usually 12MM. If the lens eyes are too far apart, patients with nearsightedness may see things unclearly, and patients with farsightedness may lead to hyperrefraction. The opposite is true if the lens eyes are too close. It is best to choose a frame with metal nose pads, which can be adjusted in height.
