1. The difference between myopia swimming and ordinary swimming moster

The shape of myopia swimming is no different from the general swimming mirror, just add the number of myopia on the spectral lens of the swimming moster,Replace the flat lens of ordinary swimming moster into a BeltAlphabeticmyopia lenses, so that patients with myopia can have clearer vision when swimming, which can improve the body sensation and quality of swimming.It is a Swimming goggles formulated for the specialty of Youshui enthusiasts who are in myopia.

The price of myopia goggles is not very different from the general swimming moster.A pair of myopia goggles is about 150 yuan to 400 yuan.It is understood that the price of the myopia swimming moster is also determined by the brand and the color of the optic lenses based on the myopia mirror.

2. Is myopia goggles the same as normal degree?

The degree of glasses worn in peacetime in myopia goggles is different, because people in the water will react in the water and use the swimming moster.Under normal circumstances, the degree of the Swimming goggles itself is about 100 less than the number of glasses worn by usual.Therefore, you must wear suitable glasses when swimming, so as to avoid affecting your vision.

3. How to choose the degree of myopia swimming moster

When choosing the degree of myopia goggles, be careful. If the number of myopia is within 150 , you do nt need to wear a swimming mirror when swimming. You can wear ordinary swimming moster normally.Although there will be a refraction in the water, if the degree of myopia is relatively low, most of them will not feel.

If your eyes have both myopia and astigmatism, then when choosing a swimming moster, you should add half the basis.Watching things when swimming will be very clear and will not affect your vision.And the degree of swimming moster is also very standard, so it will not hurt the eyes after wearing.

If the degree of the two eyes is different, you can also split the lens when buying a swimming moster.Then wear the goggles according to the degree of the left and right eyes. This is the most reasonable method, because there will be many emergencies under the bottom of the water. If myopia is very serious and wearing ordinary shadow mirrors, it will affect the visual vision.Essence

1. How to sell myopia goggles

1. Pure myopia crowd

Because the distance between the light in the water and the distance between the swimming mirror distance is closer than the frame, it is generally better to choose lower than the usual myopia 50 to 100 degrees (note: but not to wear higher than the usual degree, otherwise you will dizzy underwater)EssenceHowever, if you have a high requirements for corrected vision, it is also possible to choose a 25 degrees.

2. myopia crowd with astigmatism

The number of astigmatism can be divided by 2, plus the degree of myopia (the number of myopia + 1/2 astigmatism), and then subtracts 50 to 100 degrees accordingly, this is the ideal swimming mirror degree.

2. How to match the swimming mirror with myopia astigmatism

Take an example to explain it.

The degree of actual myopia and astigmatism:

Left eye: myopia (S value) -2.50 (250 degrees myopia); astigmatism (C value) -1.50 (myopia 150 degrees)

Right eye: myopia (S value) -2.00 (200 degrees of myopia), astigmatism (C value) -1.00 (astigmatism 100 degrees)

The appropriate degree of the swimming moster:

Left eye: myopia -2.50x0.86 = -2.15; astigmatism: -1.50x0.86 = -1.29

Right eye: myopia -2.00x0.86 = -1.72; astigmatism: -1.00x0.86 = -0.86

However, when the actual swimming moster is equipped with an integer degree of an increase of 50 degrees, the more suitable swimming mirror should be:

Left eye: 200 degrees of myopia; astigmatism 100 degrees

Right eye: 150 degrees myopia; 50 degrees astigmatism

However, for an example, this mild myopia plus astigmatism is actually enough to wear a flat -light mirror. There is no need to not be equipped with a swimming moster that is specially equipped with astigmatism.Even myopia swimming moster has rarely less than 150 degrees, basically 150 degrees or 200 degrees, and the finished swimming moster basically only has myopia swimming moster.Therefore, if the degree is high, if you want to see more clearly underwater, you must find a merchant to customize the goggles of myopia plus astigmatism.

The above is the information for reference only. If you want to match a suitable myopic astigmatism mirror, you still have to find a customized merchant for detailed consultation.

[What is a racing goggles] What is the racing mirror how to extend the performance of the swimming mirror anti -fog performance life

The racing goggles actually refer to the swimming mirror that is relatively small and the streamlined shape is relatively small.Common mirrors on the market can be called a racing mirror in general, but it is still much worse than a professional racing mirror.How to choose a good swimming goggle, the appearance, material, performance, and price of each aspect of the good shogue:

Appearance: A well -made swimming moster, the lines of the appearance should be very Smooth, have a good water resistance design, the color is very soft, and it can distinguish it from the appearance that is a racing swimming mirror or ordinary swimming mirror. At the same time, it is exquisiteThe outer box packaging.

Material: The mirror sheet uses impact -resistant polycarbonate (organic glass). The headband, nasal bridge, and mirror frame are made of pure silicone material (sand gel), which is harmless to the human body, and the feel is very soft.Comfort.

Performance: In addition to the functional distinction between the Swimming goggles, the general Swimming goggles, and the myopia goggles.A good swimming moster also has high -performance anti -fog, 100 % anti -ultraviolet treatment, sealing function, and play a role in protecting and preventing damage to the eyes.

price: A well -made swimming moster, the price of a single one is between one hundred and 45 yuan. Of course, the price of some swimming moster contains the price of the brand.

How to properly keep the Swimming goggles?

1. Do not use various organic solvents when removing to avoid deformation or discoloration of swimming moster.

2. In a wet state, putting together with Swimsuits and towels for a long time will cause stains, so put in plastic Bags or small boxes after use.At the same time, keeping it in water for a long time or moisturizing will reduce the anti -fog effect of the Swimming goggles, and it will also cause moldy phenomena.Therefore, long -term collection should be placed in normal temperature and dry and ventilated places, and talcum powder should be added to maintain.

3. When Swimming goggles, please do not place in direct sunlight or extreme high temperature to avoid causing swimming mirror deformation and performance deterioration.

4. Do not use any material to directly wipe the inside of the lens to prevent the fog film.

How to extend the performance life of swimming mirror prevention fog

1. The ultraviolet rays of the sun will destroy the anti -fog performance of the Swimming goggles. Try to avoid placing the swimming moster in the sun.

2. The anti -fog performance of general swimming moster will fail at 80 degrees Celsius.Therefore, you should avoid letting the Swimming goggles contact the thermal source, and avoid placing the Swimming goggles in the storage box irradiated by the sun.

3. The anti -fog performance of the standard swimming moster can be maintained for more than 100 hours. If the mirror surface is found when it is just used, most of the reasons are that the user swims in the unclean or oil -quality water, so that the lens anti -fog surface is attached to a one.Layer oil dirt is blocked by the anti -fog effect. At this time, as long as the oil dirt on the lens with a neutralized lens is used to restore the anti -fog performance of the goggles.

4. Instructions for the use of anti -fog function: Anti -fog agents and anti -fog membranes are all hydrophilic substances. Therefore, when consumers use Swimming goggles for the first time, they should be washed with water.Performance is fully played.

Benefits of swimming

1. swimming can enhance myocardial function

When people exercise in the water, all organs are involved in it, with a lot of energy and blood circulation accelerated to provide more nutrients with sports organs.The acceleration of blood speed will increase the load of the heart, which will speed up the frequency of beating, and the contraction is strong and powerful.People who swim frequently have excellent heart function.The effect of water during swimming makes the blood of the limbs easily return to the heart and speed up the heart rate.Long -term swimming will significantly increase the heart movement, the contraction is strong, the thickness of the vascular wall increases elasticity, and the amount of blood output per combination increases.Therefore, swimming can exercise a strong heart.

2. swimming can enhance resistance

The water temperature of the swimming pool is often 26 degrees to 28 degrees, soaking in water is fast and high, and energy consumes great energy.In order to replenish the calories emitted by the body as soon as possible, for the need for hot and cold balance, the nervous system quickly responded to accelerate the metabolism of the human body, enhance the human body's ability to adapt to the outside world, and resist the cold.Those who often participate in winter swimming, due to the improvement of the body temperature regulation function, are not easy to hurt the wind, it can also improve the endocrine function of the human body, increase the pituitary function, and increase the resistance and immunity to the disease.

3. swimming can help fat burning weight loss

When swimming, the body is immersed in water directly. The water is not only resistant to resistance, but also the heat conduction performance is very good. The heat dissipation speed is fast, so it consumes a lot of calories.It's like a ripe egg, the cooling speed in the air is far less fast in cold water. Experiments have proved that the calories consumed by Running in the standard swimming pool for 20 minutes are equivalent to the same speed on the land for 1 hour on land.The calories consumed in 14 degrees of water for 1 minute are as high as 100 kcal, which is equivalent to the calories emitted in the same temperature air.It can be seen that exercising in water will make many people who want to lose weight and achieve more effort. Therefore, swimming is one of the most effective movements to maintain body figure.

4. swimming can improve the flexibility of the body

When swimming, people usually use the water's buoyancy to lie down or lying on the water in the water.Due to the reduction of the impact on the bones during the ground motion, the chance of the bones is reduced, and the Bone joint is not easy to deform.The resistance of water can increase human movement intensity, but this intensity is different from the equipment training on the land. It is very soft. The strength of the training is easily controlled in the oxygen field.The muscles can make the whole body Smooth and beautiful.

5. swimming can help relieve stress and depression

Endorphin is a kind of good hormone that can improve people's emotions. swimming can effectively stimulate the secretion of endorphins and help people alleviate the pressure of daily work and life.

When people swim, the water of water, sweat, and fat glands in water plays a good massage effect, promotes blood circulation, and makes the Skin Smooth and elastic.In addition, during the water, it greatly reduces the stimulation of the Skin in the sweat.

7. swimming can shape muscle lines

People can strengthen the strength of the whole body through swimming.Running can improve people's legs, and swimming requires muscle coordination force in all parts of the whole body, so it can exercise the muscles of the whole body.Leg -kicking back, pulling water on both arms, stretching back, tightening abdomen to increase the strength of the legs and maintain the stability of the hip. The basic movements of these swimming make every piece of muscles of the whole body HIGH.Avoid the effect of pit fathers such as muscle unevenness that may cause equipment exercise.

8. swimming can improve Bone quality

Once upon a time, many people sneered at the view of "swimming can improve Bone quality". After all, it seems that only weight exercises can achieve this goal. However, a study published in the "Applied Physiology" magazine supports this view.Because there are some moral disputes on the human body's Bone inspection directly, the researchers then used mice as a research object and divided them into three groups: the Running group, swimming group, and control group (non -exercise).Studies have shown that Running can best increase Bone density, and compared with the control group, the swimming group does better, whether in the Bone density or the increase in the weight of the thigh Bone.It can be seen that if you want your bones to be healthier, swim!

9. swimming can reduce inflammation risk

As we all know, swimming can help enhance myocardial function and improve cardiovascular health. Related research further confirms that aerobic exercises such as swimming can help reduce inflammation risks and prevent diseases such as cardiology caused by this.In addition, reducing the inflammation risk in the entire system can also alleviate the deterioration of many other diseases and benefit a lot.

10. swimming can relieve sporty asthma

There is no more sadness than dyspnea during exercise! Compared with the dry gym or Outdoor gym in air, people can breathe wet air and improve respiratory function during swimming.Studies have confirmed that swimming can not only relieve the symptoms of asthma, but also fundamentally improve the health of the lungs.The most typical example is the Korean swimming player Park Tae -hyun.

Researchers from Australia have studied a group of children participating in swimming training courses, and with another group of children who did not study swimming,Group.The results show that children who often swim often have faster and better in terms of grasping language, learning cycling, building self -confidence, and physical development.In addition, because swimming needs to repeatedly calculate the distance of the tour, people who swim frequently are also excellent in terms of arithmetic!

12. swimming can prolong life

Everyone knows that exercise can improve health and extend life, but research has further confirmed that swimming has done the best in these two aspects.Researchers at the University of Southern California tracked and observed for 32 years of men aged 20-90 years old. The results showed that men with swimming habits are lower than men who are Running, walking or not exercising often in terms of mortality rates.Nearly half.It can be seen that if you want to live long, swimming is definitely a good dose!

Disadvantages of swimming

1. Suitable to suffer from infectious diseases
