A comfortable pair of discount prescription glasses requires comprehensive consideration of parameters, including the weight of the frame, the refractive index of the lens, the distance and height of the pupil, and the style, size, and face shape of the frame.

Learn more about the overlooked frame parameters, and when choosing frames, understand the significance of these parameters.

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

The length of the temple determines whether your discount prescription glasses can be hung on your ears, playing a role in balancing weight. The width of the eyeglasses legs can also affect the overall comfort of wearing.

Generally, eyeglasse frames are divided into two types: movable nose pads and integral nose pads. Plate frames are mostly integral nose pads that cannot be adjusted, which is very unfriendly for friends whose nose bridge is not very three-dimensional. Wearing them will cause them to slide down. However, movable nose pads can be adjusted to achieve a comfortable fit.

Various frame parameter information is usually marked on the temple, nose bridge, or lining, making it easy to find. If your prescription is relatively low, or if you choose to wear contact lenses with a frame, then the style can be more flexible.
