The rule for selecting discount prescription glasses frame height is that, when the overall looseness is appropriate, the frame size (the sum of lens width and center beam width) and your pupil distance should be smaller and thinner.

The more the shape of the lens is cut, the thinner the lens. Myopia lenses are thickened from the center to the outside, with thinner and lighter shapes. A thicker frame can cover the thickness, making it look thinner. This is the visual effect, like frameless lenses that are completely exposed, it must look thick.

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 consideration, making it difficult to choose a frame with a center distance that is completely consistent with the pupil distance.

So when choosing a frame for high myopia, all you need to do is follow one principle, which is to get as close to your pupil distance as possible. If it is slightly larger than one's actual pupil distance, during processing, it is also possible best place to buy eyeglasses to ensure that the customer's pupil distance matches the optical center of the glasses through teleportation.

For height measurements, the center-to-center distance of the eyeglass online frame is relatively small. People with high myopia should not choose large frames just to look good. This is just like the seller show and buyer show we watch when shopping online, it's easy to overturn.

There is also a standard for the allowable error between the optical center of the glasses and the actual pupil distance, and the allowable error value varies depending on the luminosity.
