It is of great significance to have a better understanding of the frame parameters when choosing an eyeglass online frame. The larger the frame shape of the glasses, the larger the retained lens area and the overall weight of the glasses will increase. If the degree is higher, the thickness will also be relatively more pronounced.

The wider the bridge of the nose, the larger the machining size calculated together with the frame. If the pupil distance is relatively small, the lens may need to be moved too much due to the distance between the pupil center and the machining center (increasing the amount of movement), ultimately resulting in the lens edge being too thick and even unable to be processed.

The ideal state is that the optical center of the eyeglasses online cheap lens is directly in the middle of the frame so that the processed glasses are thin and beautiful. The length of the mirror legs determines whether your glasses can be hung on your ears, playing a role in balancing weight. The width of the mirror legs can also affect the overall comfort of wearing.

Generally, the frame is divided into two types: a movable nose rest and an integral nose rest. The panel frame is mostly an integral nose rest and cannot be adjusted, which is very unfriendly to friends with fewer three-dimensional nasal bridges. Wearing it will slide down, while the frame of the movable nose rest can be adjusted to achieve a comfortable fit.

The discount prescription glasses frame parameter information is usually indicated on the mirror legs, nose bridge, or lining, making it easy to find. We avoid choosing frames that are too large when choosing lenses. If you have a lower degree or choose to wear contact lenses with a frame, then you can be more flexible in terms of style.
