At present, the styles of eyeglasses frames can be divided into full frame frame frame, browline frame frame frame frame, and frameless frame frame frame. There is no distinction between good and bad, and the selection is generally based on different populations and the degree of myopia.
A full frame frame is suitable for any lens, but sometimes if the frame is too small, some people may feel that their field of view is affected when looking at things.
The browline frame frame, for people with lower degrees, if the near lens is too thin, it may affect the fixation of the lower half frame edge of the lens. When choosing, caution should be exercised.
A frameless frame is only suitable for resin or PC lenses, but the screws with holes are prone to loosening, which may affect the stability of the lenses. Therefore, for people with obvious astigmatism and high lens thickness, it is important to choose carefully.
Except for obvious limitations, full frame frames, browline frame frames, and frameless frames can be freely selected. One more thing to note here is the issue of size selection.
Firstly, it is necessary to consider factors such as the wearer's facial size, pupil distance, field of view, and lens edge thickness. The size of the selected frame should be based on the pupil distance, that is, the geometric center distance of the selected frame should be as close as possible to the wearer's pupil distance, to minimize the lens displacement during installation.
Simply put, people with a wide faces should not use small and narrow frames, while those with long and thin face should not use wide frames.
