The Pupil Height Of Different Eyeglasses Frames Is Also Different

The importance of eyeglasses online cheap frame adaptation. Pupil height is the vertical distance from the pupil to the lower edge of the lens.

The vertical distance from the pupil to the bottom of the lens is the pupil height. So, the pupil height of different frames is also different.

The height of the eyes is slightly different from left to right. This is why the pupil height is also different. Some customers are also like this. So it is important to pay attention to both single lens (which is our standard nearsighted glasses) and multifocal (anti-fatigue, progressive, etc.) lenses.

In theory, when we wear and process eyeglasses online cheap, we should align the optical center of the lens with the position of the pupil.

I usually say that when wearing single-lens glasses, the height of the pupils is not very important. Experienced individuals will adjust the height of their pupils themselves. It is also best to refer to the actual installation of old glasses.

According to theory, the optical center of the lens I am holding in my hand (the red dot in the middle) should be aligned with the pupil of the eye.

However, in reality, our optical center is often lower than the pupil position. The reason is actually quite simple. Our eyes are a dynamic environment for use.

The glasses are fixed, and even multi-focus is fixed. Moreover, the visual and optical axes do not coincide, and their intersection is the viewing angle.

The difference in pupil height between the two eyes refers to the difference in optical center height between the left and right lenses. Wearing glasses is a dynamic use. We look at the distance from afar and focus on close range, and our line of sight positions differ.
