The open angle generated when the spectacles are worn refers to the angle between the frame and the temple (eyeglass leg) for maintaining a constant distance, which is the distance between the eye and the spectacle lens, when viewed from the top of the spectacles.

Conventionally, at the time of purchase of the glasses, the eyelid angle is changed by the optician's eye to deform the hinge portion or the front portion of the temple so that the angle of opening matches the shape of the face of the wearer. In this case, the adjustment of the opening angle also has an influence on the angle of the spectacle lens when worn, so that it includes adjustment so that the focus of the spectacle lens and the center of the pupil of the wearer are aligned.

However, in the case of glasses with large curves as in the case of goggles, there is a problem that the opening angle can not be obtained only by the front portion alone, but in the case of the hornet legs such as acetate, the deforming force is not good, There is a problem in that a problem occurs.

If the eyelid angle is not properly corrected, there is a problem that the focus of the spectacle lens and the center of the pupil of the wearer do not lie on a straight line, thereby interfering with the aberration and the visual field, and vomiting and dizziness symptoms in severe cases.
