Skiing is a common outdoor sport in life. Generally, it needs to wear professional ski clothes and ski shoes, and also wear goggles. This can protect the eyes, avoid snow blindness, and prevent eye protein degeneration and eye damage!
Is goggles for skiing to prevent eye protein degeneration
It has a certain effect.
When skiing, the ultraviolet ray in the sun will have photochemical effect on the surface tissue of the eye, which can make the protein coagulate and denature. This means that if you do not wear goggles, the naked eye will fall off and necrosis of corneal epithelium after being exposed to the reflected sunlight in the snow for a certain period of time, which usually occurs in 3-12 hours, most of which occur in about 6 hours. The surface of the cornea is like the skin of a baby, very smooth and delicate. When the corneal epithelium is necrotic and exfoliated, it will bring many eye irritation symptoms, such as foreign body sensation, tingling, photophobia, and tears. The eyes feel unable to open, and the tears on the eye surface will increase.
At the same time, for most ice and snow sports, such as short track speed skating, wearing goggles is actually to avoid sports injuries. Qualified goggles can prevent eye burns caused by ultraviolet rays, effectively filter light harmful to eyes, and maintain brightness and wide vision. The professional goggles can also protect the eyes from the cold wind impact caused by high-speed movement on the ice.
What do you wear goggles for skiing
1. Prevent snow blindness.
2. Prevent eye irritation caused by high wind.
3. Increase the clarity of visual objects.
4. Prevent eye damage caused by foreign objects. Special goggles also have special uses, such as anti ultraviolet, anti fog, etc.
5. Provide physical protection for eyes
In the ice and snow sports, athletes can run fast. Take the sled race as an example, the maximum speed can reach 145km/h. The speed and passion pursued by ice and snow sports are often accompanied by the splashing of ice particles. In this case, the ice particles are caught in the strong wind, and goggles provide a protective barrier for athletes' eyes to avoid eye injuries.
6. Moisturizing
During the competition, the air is cold and the movement speed is fast. The tears on the surface of the athletes' eyes will evaporate rapidly, resulting in very dry eyes, which will affect the performance.
Precautions for skiing
1. Warm up exercise is indispensable. Before formal skating, you must warm up and press the leg to twist the waist.
2. Before skiing, skiers should carefully understand the height, width, length, slope and direction of the ski path, and select a suitable ski path according to their own level.
3. Control the distance with others. When skiing, beginners should keep a certain distance from others to avoid collision.
4. Never blindly seek speed. Learn to maintain speed, step by step, and act according to your ability. Skiers must slide slowly or stop sliding in places with crowded ski trails, poor visibility or even obstacles.
5. Clothes are warm and sharp. Can wear knee pads, wrist guards, can play a certain role in protection. Wear gloves and earmuffs in cold weather. Wipe off sweat and wear clothes in time after practice to prevent colds and frostbite. When exercising, you can take a pot of ginger tea to drive away cold and prevent colds.
