What is the appropriate difference between the actual pupil distance and the center distance of the discountglasses frame when choosing a frame for high myopia? In theory, the closer the center distance of the frame, the better, and the more aesthetically pleasing it will be.

However, in fact, when choosing a frame, personal preferences, materials, styles, etc. are taken into account, and it is difficult to select a frame with a center-to-pupil distance that is completely consistent.

So when choosing a frame for high myopia, there is only one principle to follow, which is to get as close to your pupil's distance as possible. If it is slightly larger than one's actual pupil distance, during processing, the pupil distance can also be ensured to match the optical center of the discountglasses by moving the center.

It is more suitable for height measurement, as the center distance of the frame is relatively small. There are standards for the allowable error between the optical center of glasses and the actual pupillary distance, and the allowable error values vary depending on the luminosity.

Choosing a small frame for high myopia is not wrong, but for people with large faces, what if the frame is too small to fit? People with high myopia with a large head are prone to situations where the size of the lens ring is appropriate when choosing a frame, but the legs are too narrow on both sides, causing them to pinch their faces and fall.

So, when choosing a frame, it is important to pay attention and try to choose frames with widened legs. What is a widening design? It is a design that extends outward at the frame post so that while the size of the eyeglasses ring remains unchanged, the width on both sides of the eyeglasses legs can be increased to meet the comfort of customers with larger heads.
