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.

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.

How to extend the life of running shoes

1. Do not wear running shoes for other sports, such as basketball, football.Different roads have a huge degree of wear on running shoes. Running on the road is far more than expenses on the forest road.In the case of conditions permit, try to run on a professional runway such as plastic.

2. Try not to run on rainy, snowy, and exposed to asphalt roads.A pair of running shoes should be "rest" for two days. Wearing the same pair of shoes for a long time will accelerate the aging and dehydration of the shoes. Proper "rest" can restore the shoe in a good state and keep it dry, which is also conducive to relieving foot odor.

3. Put/take off shoes in a gentle way.When we are in a hurry, we often stuff their feet directly into the shoes. Over time, we will cause irreversible deformation to the shoe help part.

4. run shoes will be tighter after cleaning and exposure, so don't wash shoes with high frequency.After the surface of the Running shoe appears dirt or colored marks, apply an appropriate amount of water or detergent on the old toothbrush or soft hair brush, gently wash, and then rinse it with water.Note that it is not recommended to flatten the wet shoes when it is dry. Instead, it is not recommended to put the toe to the bottom of the shoe to the wall and dry at the ventilation of the room temperature to prevent water from being immersed in the middle soles.
