Why Do Glasses Slip Easily?

We often see a lot of articles about how to choose glasses that are right for you. In my opinion, glasses should be clear, comfortable, long-lasting, beautiful and stable. Yes, the glasses should be stable when worn on the face. If the glasses are unstable, the glasses will often slide down and cause a lot of problems, especially with myopia glasses.

When matching glasses in an optical shop, they will generally test your various data, degree, interpupillary distance and astigmatism. Looking at things from the center point will produce a prismatic effect, causing eye fatigue, which will increase the degree unconsciously and cause damage to the eyes.

If the glasses slide frequently, causing the optical center point of the glasses to deviate, adjust the glasses or buy a new pair of correct glasses. The following suggestions, I hope to help you.

one. Frames don't just look good or not, fashion or not, but also the right size. If it is too large, it will be loose and easy to slide down, and if it is too small, it will not be strong and easy to slide down. If you don't choose the right glasses at the beginning, it will be inevitable to slide down later, so the choice is very important! When trying on glasses, you need to feel more whether the width and tightness are appropriate.

two. The glasses can be stably worn on the face, and there are 3 stress points:

1. The first point of force is the nose pads. The function of the nose pads is "load-bearing", and the main weight of the glasses is borne by the "bridge of the nose". If this point is not stressed, it cannot be stabilized. Especially for people with high myopia, the lens is heavy and cannot be well placed on the bridge of the nose, "top-heavy" and easy to slide down. The nose pads of the metal spectacle frame can be adjusted by yourself, the stipules on both sides should be balanced as much as possible, and the angle should be adjusted according to your own nose shape. The integrated nose pads of the sheet metal frame cannot be adjusted. Determine whether the whole pair of glasses is deformed. When laying flat on the table, whether the four points of the circle and the spleen touch the table at the same time, and if the four points are placed in reverse, whether the four points touch the table at the same time. Plate glasses are adjusted by practitioners.

2. The temple foot cover part hooks the ear. This force is also important to ensure that the glasses will not move back and forth easily. Even if the force on the bridge of the nose is not good, as long as the ears are hooked firmly enough, you can wear them when you are not exercising, but the comfort is relatively poor. Therefore, when choosing glasses, according to the size of your head, the spleen should not be too long or too short, just enough.

3. Mirror legs clip face. This part mainly depends on the width of the frame. Too wide or too narrow can make the glasses unstable and uncomfortable.

To be stable and comfortable, only the weight of the glasses can be reasonably distributed to 3 points of force. Knowing the 3 points of force, you will know how to adjust the frame when you encounter glasses that are easy to slide down. In fact, in the eyes of our glasses manufacturers, adjusting the frame is very simple, it is nothing more than strengthening the force of these three points. As for how to adjust the frame, it depends on where the specific problem is. If you don’t understand it yourself, it is recommended to ask a practitioner to adjust it, so as not to break the glasses when adjusting the glasses.
