Why don't the optical glasses of hurdlers fall off?

At the 33rd Summer Olympic Games, Xu Zhuoyi, a 110-meter hurdler known as the "optical glasses flying man", unfortunately missed the finals, but he attracted widespread attention and heated discussions on social media because he wore optical glasses to hurdle. "It turns out that you can do track and field with optical glasses?" "Won't glasses fall off?"... Behind this, there is a science of fitting glasses.

Whether glasses fall off is related to the size of the optical frame

When choosing a optical frame, light and comfortable are the first choice. But you can't simply pick a pair of light optical frames, especially for high myopia above 600°.

You also need to consider the matching of the frame shape with the face shape, the size of the frame, etc.

Optical frames are divided into full-frame, half-frame and frameless. Full-frame glasses are suitable for almost everyone, especially for high myopia. The "hurdlers" Olympic athletes choose full-frame. Half-frame frames are relatively light without the lower frame, and the lower frame is fixed by wire drawing, and the stability is also good. Although frameless glasses are light, they are not supported by the frame, and the connection between the lens and the temples is fixed by screws, which is not stable. It is generally not recommended for people with high degrees to wear them.

Whether the glasses fall off is related to the material

In addition to the type of frame, if you want to wear lightweight glasses, starting with the material is also a way.

Alloy and plate materials are more common. The advantages are diverse styles and high aesthetics, but there is no advantage in weight.

Titanium frames are more popular materials in recent years. They have excellent texture and lightness, but the disadvantage is that they are a little expensive.

In addition to feeling light, the weight ratio of the frame and the temples also needs to be balanced. When you wear it, you feel that the frame does not press the bridge of the nose, and the temples do not hurt the ears, and the frame will be more comfortable.

Whether the glasses fall off is related to the nose pad

Whether the glasses frame is stable or not, the nose pad is the key point, and it is also the most easily overlooked point.

For example, if you have a low nose bridge, try not to wear an integrated nose pad. It is completely unadjustable and basically cannot be supported.

S-shaped nose pads are the gospel for low nose bridges!

The S-shaped nose pad has a wide adjustment range, which can make up for the lack of nose bridge height. It can also be adjusted in all directions according to the shape of the nose bridge, so that the nose pad can be firmly attached to the nose bridge.

People with high nose bridges should give priority to straight nose pads.

Of course, if you choose nose pads according to the above method, but it is still uncomfortable to wear, you need an optician to help - adjust the nose pads.

Whether the glasses fall off is related to the temples

In order to get a pair of glasses that will not fall off even when crossing hurdles, in addition to the frame and nose pads, the temples are also very important.

The right temples can hook the ears, and the wrong temples will make your head dizzy.

The right temples need to be tried on, and you need to feel that the middle part of the temples does not pinch the face, and the back part can just hug the back of the head. Only then can you choose the right temples.

Finally, you have to put on the glasses and shake them bravely to feel the tightness of the glasses. Don't worry about them flying away. The glasses that can't be shaken off are the real suitable glasses.

It is recommended not to fit glasses online. After all, fitting a pair of comfortable glasses requires a good optician. Unsuitable glasses frames may also cause visual distortion, visual fatigue, and other conditions, which may damage the health of the eyes.

However, in order to wear glasses comfortably, in addition to fitting them well, they also need to be well maintained. Do not take off your glasses with one hand to avoid deformation of the frame. If the frame is loose, do not bend it yourself, but find a professional to adjust and repair it in time, especially the nose pads. Replace the frames and lenses regularly.

Choosing a suitable frame is not only a care for your eyes, but also a respect for your dreams. Let this professionalism and care accompany you to overcome every obstacle and sprint towards higher honors.
