What is lens refractive index

The lens refractive index is the ratio of the speed of lighting in real vacuum to the spread of light in the lens material, which reflects the lens's refractive ability to light.

At present, mainstream resin lenses on the market are: 1.56, 1.60, 1.67, 1.71, 1.74 and other types.Under the same prerequisite, the higher the refractive index of the lens, the thinner the lens, the lighter.

Speaking of this, many friends are very happy, of course, I hope that they can be equipped with a light and thin glasses!But don't ignore another problem: Generally, the higher the refractive index of the lens, the lower the number of Abbe, and the more obvious the color scattered.Because the scattering will affect the imaging effect of the medium, we measure the imaging quality of the lens through Abei.The higher the number of Abe, the smaller the color scattered, the clearer visual effect.Abe's number is too low, which will make the lens a rainbow pattern, affecting the user's visual clarity.

Therefore, the higher the refractive index is better, the better the lens refractive index must be selected to better protect the eyes.

What is the refractive index of polarized lens

The refractive index of polarizing lenses is not high. Generally, the refractive index of the selection of myopia below 500 degrees is 1.56. If you need to consider the thickness of the glasses, you can also choose the refractive index of 1.60 and above.The price of polarized lenses with higher refractive indexes such as 1.71, 1.74 is also higher, and you need to customize it. You can choose according to your own needs.

Generally speaking, polarizing glasses do not need to be worn all the time, and mostly use it during outdoor sports, so the ordinary 1.56 refractive index can meet most of the requirements.

The benefits of high lens refractive index

1. For people with a height, wearing thick lenses all day not only easily cause visual fatigue, but also easily cause compression or cause the glasses to decline or pain in the ears.The high refractive index lens refractive index will be relatively thin and lighter, and it is usually relatively comfortable to wear.

2. Too thick lenses will not only make the wearer have a sense of depression, but also affect the aesthetics of the wearer. The relatively thin lens will look better.

3. Compared with low refractive lenses, high refractive lenses are better than lenses with low refractive indexes than lenses with lower refractive indexes.

How to choose the right lens refractive index

1. Patients with myopia below 200 degrees are recommended to use a 1.50 refractive lens.

2. Patients with myopia below 600 degrees are recommended to use a 1.56 refractive index lens.

3. Patients with myopia below 800 degrees are recommended to use a 1.60 refractive index lens.

4. Patients with myopia below 1000 degrees are recommended to use a 1.67 refractive index lens.

5. Patients with myopia below 1000 degrees are recommended to use a 1.74 refractive lens.

Ski shoes can be cleaned. Specific methods: First use a soft brush to brush the surface of the shoes, and then wipe it with a wet towel. Apply one direction, of course, some shoe powder will fall. This is the first time. After all wipe it, brush it with softly, so that the Flour will be covered evenly, and the other on the surface of the shoes will also be affected. clean up.Then apply the shoe powder again, and add the place where there is no uniform in front. If you need it, you can use it The soft brush is properly applied to the brush evenly.What needs to be reminded is that you cannot clean the inner liners of Ski shoes, take it out to dry, and then put it back.

2. Can Ski shoes be blown with a hair dryer?

Ski shoes can be blown with a hair dryer, but you need to pay attention to methods and safety. It is recommended to use cold or low -end hot air to avoid high temperature damage to the upper and materials.

1. First of all, it is important to choose the right hair dryer mode and temperature.Generally speaking, it is recommended to use cold or low -end hot air for drying.Because too high temperature may cause the upper and internal materials of Ski shoes to be damaged, and may even cause hidden safety hazards such as fire.Therefore, when drying Ski shoes, you must avoid using high temperature or strong wind.

2. Secondly, we need to loosen the laces of Ski shoes so that the air can flow inside the shoes.In this way, the hair dryer can more effectively scatter the moisture inside the shoes and speed up drying.At the same time, we also need to pay attention to keeping the hair dryer from a certain distance from Ski shoes to avoid excessive distances that cause too much calories and damage the shoes.

3. In addition, in order to ensure the drying effect of Ski shoes, we can also consider using some auxiliary tools.For example, some desiccants or newspapers can be placed inside the shoes to help absorb the moisture in the shoe.At the same time, put shoes in a good ventilation place, it also helps to speed up drying.

4. It should be noted that although the hair dryer can dry the Ski shoes, it does not completely replace the natural drying.Therefore, in the case of conditions permit, we still recommend that the Ski shoes are dried naturally as much as possible.This can better protect the material and performance of the shoes and extend its service life.

Third, Ski shoes daily maintenance and storage method

The daily maintenance of Ski shoes also needs meticulous care.After each skiing, make sure that the buckle of the Ski shoes is fastened to keep the shoe shape.If there are snow in the Ski shoes, remove the inner shoes and wipe it separately, and dry it naturally in the warm place. Do not use heating or stove to bake to prevent the outer boots from being heated.After the snowy season is over, completely clean the inside and outside of the Ski shoes and dry it.In order to keep the shoes dry, it can be plugged into the newspaper and exhibited in a dry and humid place.Such daily maintenance can ensure that Ski shoes are in the best state and extend their service life.

What are the functions of the car navigation instrument?

1. Location upload: The satellite positioning instrument will upload the parsed position to the background server through the mobile Internet.

2. Real -time positioning: The satellite positioning instrument can collect information about satellite in real time and analyze the information.

3. Session function: After the satellite positioning instrument is positioned, the time accuracy can reach nano seconds.

4. Oil break function: The satellite positioning instrument can remotely break the oil. After the oil is broken, the vehicle will be turned off and will not be started.

5. Speed alarm: You can set up speed warning prompts in the navigator. The alarm will be alarm during the prescribed road section and prescribed operating time, and the bee singer installed in the car makes a noise.

6. Automatic navigation: voice prompts to turn, turn around, etc. The screen shows the information of the map, the location of the car, the speed of the car, the distance between the distance of the destination, and the departure of the driving track also provides a re -planning route function.

7. One -click alarm: The satellite positioner supports the one -click alarm function. In emergency situations, you can send alarm for help.

8. electronic dog function: Through the speed measurement information recorded in the library, the pronunciation reports prompt early warning information in advance.It should be noted that if there is no recorded information point of the ground gallery, the prompt will not be issued, and some car navigator electronic Dogs do not have its own radar chip's unable to warn the flow speed measuring instrument.

precautions for the use of car navigation instrument electronic Dogs

1. It is best to mobilize the car first, and then insert some cigarettes.After the navigation is over, unplug the cigarette lighter, and then insert it after the car is launched next time. This will help protect the machine battery and extend the service life of the battery.

2. After use, follow the order of shutdown: close the page first, then shut down, and finally unplug the plug.Some car owner pictures are convenient, and the plug is pulled directly after use. It never shuts down.

3. Do not put the electronic dog in the sun for a long time and expose the sun. The larger temperature difference not only affects the battery life, but also affects the touch sensitivity of the LCD screen.It is best to put it away after use, do not put it in a prominent position on the car, so as not to provoke a thief.

4. It is best to charge for about 10 hours in the first three times, so that the battery power storage capacity is maximized.

5. Do not let the navigation screen contact sharp objects.

6. The electronic dog function of the navigator is not necessarily accurate and perfect. Some sections do not prompt speed warning, but there are mobile speed measured vehicles for radar speed measuring. Therefore, you cannot just rely on the navigator electronic Dogs to reverse the speed.Of course, to abide by traffic order and control speed in the specified range is the safest.

7. Pay attention to the update of the internal data of the navigator and the upgrade of the electronic dog to avoid the warning prompts cannot be received in a timely manner due to the inadequate data update.

1. What is a Bone Belt

Bone Bone refers to a kind of knee protective gear that protects people's knee joints, which consist of fabric and rubber hose or EVA alien strip.mountain climbing, ball movement, etc. are used to prevent damage caused by movement.

2. What is the role of the Bone band

The knee is an extremely important part in exercise, but also a relatively fragile and easy -to -injury part. It is painful and difficult to recover when injured.point:

1. Fixed Bone

Due to the special location of the cymbal Bone, there are no other bones around the surrounding Bone connecting it. The Bone Bone will be prone to shift during a large intensity exercise, and the Bone Bone Belt mainly plays the role of stabilizing the Bone, thereby avoiding the shift of the Bone.

2. Relieve the loss of half -moon board

The half -moon board is one of the indispensable compositions in joint composition, which mainly plays a role in increasing joint stability and buffering shock.It is precisely because of the functional characteristics of the Moonboard. It is easy to bring losses in exercise.The Bone band played a upper and lower effect. By selecting the rubber hose with the proper hardness and thickness, it can reduce wear.

3. health care and nursing effect

The harmonious sports such as Running and mountain climbing damage to the knee, especially fast Running or down the mountain, causing pressure and loss to the knee joint cannot be underestimated. At this timeIt can also effectively avoid pain and play a good health effect.

Third, there are any side effects on the Bone band band.

Wearing a Bone Belt can protect the knee and half -moon board, but if it is not worn, it may bring some side effects to the body. Under the case of improper use, the side effects of the Bone band are mainly:

1. Weak muscle strength

The main function of the Bone band is to provide support for abnormal bones, which can reduce the force of bones and muscles.After a long time, it may lead to insufficient muscle strength, and physical reactions such as weakness and numbness of the lower limbs and numbness of the legs and feet may be not conducive to normal work or walking.

2. Affects blood circulation

The blood vessels in the legs have the effects of transporting blood and oxygen. If the patient wears the Bone tightly, it is easy to compress the Skin and subcutaneous blood vessels, resulting in poor blood flow.Due to insufficient blood supply, it may cause response such as cold legs and feet, weakening perception, and is not sensitive to the response to hot and cold.

3. increase pain

Long -term improper use of the Bone band may cause sterile inflammation, tissue and nerve damage, and cause patients with persistent pain. Generally, it is dull pain or tingling, which affects normal life and work.
