The cheapest eyeglasses can provide good corrected vision for people with refractive errors, which is their biggest advantage. Wearing glasses can help them see things.

Myopia lenses are concave lenses, whose physical property is that they shrink when looking at things, and the higher the degree, the more obvious it becomes. When fitting discountglasses, it is necessary to ensure that the pupil and the optical center of the lens coincide.

Since the eyeball rotates in daily life, it is inevitable to see things through an eccentric area, which can cause distortion and deformation of the view. The more the gaze reaches the edge, the more obvious the deformation becomes, and the feeling of turning back and shaking is the main problem that people may feel dizzy when wearing glasses.

The best solution to minimize distortion in viewing is to choose a smaller eyeglass online frame (with the center of the frameset close to the pupil distance); Choose visually optimized lenses; Choose lenses that are suitable for refractive index and are as thin as possible to minimize distortion when looking at things.

How to choose a frame for high myopia? The frame pupil distance should be close to the actual pupil distance (with the eyes in the middle of the frame), should not be too small, and should not be pinched (both too large and too small are prone to slipping).

Glasses must be stable when worn, and for high myopia, consideration should be given to adding heavier lenses in front. It is recommended to choose full-frame lenses as it is not easy to see thick lenses visually. Try to choose board materials as much as possible. The thickness of the board and the thickness of the covering part.
