(1) Clear and broad visual experience

1. Selection

If the degree of the wrong myopia swimming moster, dizziness and vague vision will appear, but the degree of goggles that should be selected is not the actual degree of myopia. Because the refractive index of water is higher than that of air, the degree must be compared to the frame glasses worn by the usual frame glasses wearing it.Low.But how much should I choose?The standard provided by ophthalmology experts is:

2. What should I do if the swimming ear water is in water

Many people go swimming in summer, and often encounters ears into water. Because water has a certain tension, after entering the narrow outer ear canal, a barrier is formed and the outer ear canal is divided into two sections.The side pressure maintains the balance of the pressure on both sides of the water barrier, so that the water is not easy to flow out automatically.

Sometimes there is a large barrier in the outer ear canal, so it is easier to wrap the water around the ear canal around the after entering the ear canal.After water in the ear, the ears will be stuffy, the hearing decreases, dizziness, and is very uncomfortable, so people are often very urgent to discharge the water.Some people even use unclean clips, match sticks, small keys, etc., so that although the water barrier can be broken and the water flows out, it is also easy to damage the external ear canal and even the tympanic membrane, leading to ear disease.

Third, the water should be discharged in time after water in the ear. The most common method is:

1. Single -foot jumping method:

The ears are down, and the gravity of the water borrows the water to flow out of the ear canal down from the outer canal.

4. Side lying method:

After trying the above methods, lie down and lie on the side when you sleep at night, that is, the ears that enter the water, but do not block it, because the air pressure will affect the flow of the water after it is blocked.

Because the swimming pool or river water is not clean, the sewage causes the Skin and tympanic infection of the outer ear canal and the tympanic membrane after the ear, or it is not treated properly after the water inside the ear. Obstruct, tympanitis, purulent otitisitis.If the above symptoms occur after water in the ear, you should temporarily stop swimming and go to the Hospital for examination.

When water just enters the ear canal, it may not be deep, so the easiest way is to drain the water with one leg.You should go ashore immediately. If you are in the right ear, your head is biased towards the right, the right leg is beating, the left side, and so on. In general, the beating can be drained several times.

If the water enters deeply, it cannot solve the problem in doing so. You can use oily ear drops, such as 2%phenol glycerin drops to ear ear, and once every 3-4 hours. Generally, you can change the unclean water to replace the water.Come out to avoid otitis media.In emergency situations, you can't get ear drops for a while, but most people will prepare eye drops when swimming. Most of the swimming places will also prepare eye drops. You can also use the ear canal with eye drops that do not fail and have no ototoxicity.But afterwards, you must use oily ear droplets to replace water as soon as possible!

Therefore, for those who swim in summer, in addition to preparing eye drops, 2%phenol glycerin drops should also be one of the essential drugs.

It is inevitable that the ears will enter the water when swimming. After taking a bath, the water of the swimming pool remaining in the ears has basically flowing on its own.However, sometimes due to more earwax, a small amount of sewage retention ear canal causes inflammation of the ear.In order to absorb the remaining water and sterilize and anti -inflammatory, you can drip 3-6 drops of medical alcohol into the ear canal after the bath, and stop for a while to let it flow out naturally.

5. How to prevent the ears from entering water

1. Do a good physical examination before swimming.When there is a cricket in the outer ear canal, it should be taken out, otherwise it will easily cause pain after soaking.People with otitis media, such as perforation of the tympanic membrane, and dirty water into the middle ear, can increase otitis media.Therefore, patients with otitis media must be swimming with the consent of the doctor.

2. Use dehydrated cotton with vasel oil during swimming tightly to the outer ear canal, which can play a protective effect.

3. After swimming, excrete the accumulated water in the external ear canal.When drainage, the head is tilted to the side of the water, and the head can be drained with the palm of the same side to drain the water.If itching in the ear, you can use 75%alcohol cotton to gently wipe the external ear canal to disable the hand digging.If you feel pain in your ears, you should go to the Hospital for treatment in time.
