The Magic of Polarizer Filter

Are the sunglasses the same? One kind of sunglasses will make the light less dazzling. It can even help the fisherman to see the situation under the water more clearly. We call it polarized sunglasses. However, what is polarized light?

We know that general light is not polarized, that is, its electric field oscillates perpendicular to the forward direction, but does not follow any particular direction; however, if polarized light is an incident, we can use a polarizing lens block this light completely.

Therefore, if the sunlight reflected from the surface of an object is polarized, we can block this sunlight with a polarizer film at a specific angle. If you drive towards the afternoon sun, the reflected light from the road will be strongly polarized and parallel to the road. At this time, wearing polarized sunglasses will block the polarized glare and let only the vertically polarized light to enter.

On a microscopic scale, this blocking effect means that the long molecules in the filter are aligned horizontally and will absorb light with horizontal polarization (the electric field also oscillates horizontally). Therefore, most of the dazzling reflections have been eliminated, but the brightness of other surrounding objects is not decreased. This is the principle of polarized sunglasses.

The fisherman uses polarized sunglasses to reduce the sunlight reflected on the water surface, but still sees the light reflected by the fish, the same principle. For unpolarized sunlight, the reflected light is mainly horizontally polarized light.

However, the light reflected from the fish is not polarized light, so as long as the fisherman wears polarized sunglasses that can block horizontally polarized light, the light reflected from the fish will pass through the fisherman’s polarized sunglasses, so the fisherman can see a fish when you can’t see the glare of the water. However, if the depth of the fish is more than 1.5 meters, the above explanation is not completely correct, because, above this depth, small particles suspended in water will scatter light, making the light become horizontally polarized light.

Polarized lenses are also used in entertainment. The so-called stereoscopic film is to use polarizing lenses to make the left and right eyes receive light with different polarization directions, respectively, so as to cause a difference in viewing angle, so a stereo effect appears. The picture on the right is the “stereo glasses” necessary for watching a stereo movie, which is just a combination of two polarizer film filters with different polarization directions.

Acupuncture work

Chinese traditional medicine is considered very effective. It consists of many unique methods of treating diseases.

Briefly on the term “acupuncture”

Acupuncture (acupuncture) is an ancient Chinese treatment method. During the procedure, the patient is injected with special needles into the biologically active points. According to Chinese theory, it is believed that the Qi energy is flowing in a person, and only this energy can ensure good health. If it starts to stagnate, various diseases occur. There are over 500 such active points on the human body. They are all connected to each other.

Acupuncture can really help with a problem with any system of the body.

How does acupuncture work?

A course of acupuncture can only be performed by a specialist who has appropriate training and a license. A person must know when and in what place to insert needles depending on the disease.

The session usually takes place in the comfort of a warm, quiet place on a soft couch. The right amount of needles is injected into a certain part of the body (depending on the problem). The patient usually feels nothing and there is no pain. The session lasts for 15-30 minutes. Then the acupuncturist takes the needles out.

Three to 15 sessions may be needed to improve your health. Everyone feels differently after the treatment. Some feel relaxed and sleepy, others feel a burst of energy.

What can and can’t be done after the procedure?

Immediately after the session, it is recommended that you just lie down for 10-15 minutes and drink water. But these are not all the rules that must be observed. For the duration of the treatment and for two weeks after it, you can’t:

  1. Take any alcoholic beverages. Keep coffee and tea to a minimum. It is better to ask your doctor how much you can drink per day.
  2. Heavy physical activity. Many people feel so energized after the first sessions that they are ready to do something and exercise around the clock. This is not the way to do it. It is better to let the body rest.
  3. Strong drugs like antidepressants, painkillers, and antibiotics are forbidden. Before starting therapy, it is better to ask a specialist about the compatibility of medications and acupuncture.

And the most important point is that for effective results, you need to take a full course of acupuncture. Some patients see an improvement after the second or third time and decide that they have had enough. This is categorically not the way to do it. Only a completed course can benefit the body.
