Can riding glasses ski

If you want to ride a bike, it's good to wear glasses. If you want to wear sunglasses, you need to wear glasses with degrees

In fact, avoiding light is not to weaken the light as sunglasses do. It is mainly to absorb and reflect the ultraviolet light under strong light and the cold strong light under the sun. Because in the strong light environment, the sun reflects all kinds of rays and strong light on the road or other environment, which will cause eye fatigue, sour and other discomfort. The common riding glasses do not have the kind of sunglasses, They are mainly light color, which can effectively absorb and reflect rays to prevent eye fatigue. Third, sand prevention, that is to say, to prevent dust and flying insects from entering the eyes, which is often encountered when riding in windy and sandy environment or in the wild, that is to say, to play a direct role in practice. In fact, the first and the second of the three major performances of riding glasses are particularly important. The principle of turbulence of the windlass, and even some fully sealed designs, and the material of the lenses directly determine the performance and grade of the riding glasses.

Most riders ride on roads, and on a sunny day, roads reflect sunlight better than mud or grass. Because of the different riding posture, cyclists have more time to look directly at the road than ordinary cyclists, and thus receive more ultraviolet reflection? The eye absorbs ultraviolet ray for a long time can cause cataract! Most of the cyclists have tears in their eyes and foreign bodies in their eyes, right? If you are riding in winter covered with snow everywhere, or in Tibet covered with ice and snow all the year round, the sun reflects on the snow and directly shines on your eyes, you are easy to suffer from "snow blindness". Riding glasses can greatly protect your eyes from these injuries.

Skiing is a whole body exercise, which is beneficial to the exercise of limbs, heart and lung. However, if you don't do some auxiliary exercises before skiing, it may be harmful to your health. Here are some suggestions from foreign ski experts.

1. Training: no sport like skiing can keep the body bent for a period of time and put the knee under pressure for 4 to 6 hours. So more training is very helpful for skiing. Squatting training, flexibility training and uphill riding are all effective training methods. 4. Lie on your skis and try to stand up. If not, do more stretching. Swimming training can quickly improve cardiopulmonary function and flexibility. 5. Arthritic knee joint dysfunction is fatal to skiing. It can be improved in three ways: using glucosamine to lubricate the joints, injecting other drugs to lubricate the knees, or seeking the help of a physical therapist. A friend with arthritis had better ski new snow. 6. Older skiers are better equipped to wear soft snowshoes, and the comfortable posture is medium standing posture. There is also the use of new equipment.

7. Snow stick

People who are most likely to be injured after falling are usually holding the snowstick with their thumb through the holding strap, so many people do not recommend using the holding strap. 8. Fixator in recent decades, the technical improvement of fixator is very limited. Fixators that can be released on both sides of the toes and heel may be better, but there is no clear data to suggest that this reduces the risk of knee ligament injury. The most common problem in skiing is that the fixator is too tight.

Unless you jump, race or slide on a hard snowpack, the retainer setting should be below the recommended value. The damage caused by automatic disengagement of fixator is far less than that caused by failure to open fixator.

When skiing, beginners can try to keep balance with a holder.
