4. Myopia, 1. Astigmatism, how many degrees of swimming goggles should you choose? 10

First, understand what type of myopia you have. Myopia is divided into true myopia and pseudomyopia.

In the case of pseudomyopia, vision can be restored to a certain extent by taking proper rest and correct eye exercises, avoiding overuse of the eyes.

In the case of true myopia, proper rest and correct eye exercises can relieve eye fatigue and prevent myopia from progressing, but it cannot restore vision. True myopia can be corrected with ultra-fast all-laser surgery, but not everyone can have laser surgery. The patient needs to be at least 18 years old, have no diseases and inflammation in the eye, and have sufficient corneal thickness, etc.

Before the operation, the regular eye hospital will give the patient a very detailed examination to ensure the effectiveness of the surgery and the safety of the patient.

If you don't want to have surgery, you can consider wearing orthokeratology lenses, which not only correct your vision, but also control the progression of myopia very well. Moreover, orthokeratology lenses are very convenient, you only need to wear them when you rest at night, and you can see clearly without glasses during work and study during the day.

Most optometry in optical stores is a simple computerized optometry, which can detect the prescription, but the optometry is not accurate and comprehensive, and it is not possible to determine whether it is true myopia. At the same time, wearing glasses with inaccurate prescription can harm the eyes and deepen myopia.

It is recommended that you go to the hospital for dilated refraction (the use of cycloplegic agents to refraction the patient while at rest) to determine whether you have true myopia or pseudomyopia, and then decide on a plan to restore your vision.

1. Due to the refraction of light in the water and the distance between the swimming goggles and the eye is closer than the frame, it is generally better to choose 50 100 degrees lower than the usual myopia (note: but do not wear higher than the usual degree, otherwise you will be dizzy underwater).

For example, if the myopia is 500 degrees, then when choosing swimming goggles, you should choose 400 or 450 degree lenses. As mentioned above, the minimum power of myopic goggles is 150 degrees.

If the prescription of your glasses is less than 150 degrees, it is recommended that you wear flat goggles.

If the prescription of glasses is 275 degrees, it is recommended to choose 200 degree swimming goggles, but if you have high requirements for corrected vision, it is okay to choose to lower 25 degrees.

2. People with astigmatism can divide the degree of astigmatism by 2, add the degree of myopia (myopia power 1 2 degree of astigmatism), and then subtract 50 100 degrees accordingly, so that it is the ideal power of swimming goggles.

3. People with different degrees of myopia in both eyes should also choose different degrees of left and right eyes for consumers with different degrees of myopia in both eyes. The power selection method for each eye is handled accordingly in the above two cases.

There is basically no astigmatism in myopia goggles, so it is recommended to choose 400-degree myopia goggles.

How to choose the power of myopia goggles.

1. Due to the refraction underwater, it is recommended to choose myopia goggles that are 50-100 degrees lower than the eye power.

Because of underwater refraction, myopic goggles are 50 degrees lower and basically can't be felt; If there is astigmatism, it is advisable to add half of the astigmatism on the basis of the myopia power when selecting the power.

For example, if myopia is 200 degrees and astigmatism is 100 degrees, 200 degrees of myopia goggles are selected according to the calculation of 250 degrees of myopia.

2.The power of the two eyes is different, how to choose the right myopia goggles?

It is recommended to choose goggles that can be freely combined with glasses and frames.

If the prescription rises in the back, or the lens is damaged, it is easy to replace it, and there is no need to replace it again.

Myopia goggles should pay attention to quality, waterproof, anti-fog, and good adsorption.

People with myopia should pay attention to bacteria when swimming, and try not to get into their eyes. This is especially true for people with high myopia.

The problem of myopia has begun to move towards a younger age, and many children have been myopic since childhood. This not only brings a very serious safety hazard to children, but also makes many parents worry about the time, for children under the age of 18, because of the strong ocular accommodation at this time, it can also be improved by drugs. It is recommended to use Leyan nutrients to treat I, take it with warm water twice a day, and you can slowly reduce the degree of myopia by insisting on using it.

You can fold it down, choose 250 degrees, and the astigmatism is folded in half to the myopia.

Condition analysis: Hello friend suggests that you should best diagnose and treat the mydriasis in the hospital, which is more accurate, usually pay attention to rest to ensure that the ciliary body is fully rested and adjusted, and actively ophthalmology ** as well, I wish you good health Welcome to consult again.

Suggestions:

The choice of the power of myopia goggles is to reduce the power of your shallower glasses by 50 degrees Astigmatism does not have Your situation is 425-50 = 375 Buy 375 degrees can be so accurate may not be the original There may not be many original matches You can specially match the 350 degrees in the general specifications.

Astigmatism 2 + myopia, then subtract 50-100 degrees. This is the ideal goggle power.

400 degrees of astigmatism is relatively high, the so-called astigmatism is actually the uneven surface of your cornea, when the light enters the eye, the refractive index increases, resulting in blurry, double vision and so on. It is best to wear glasses, otherwise it will cause your myopia to deepen in the future.

Important to wear

I have a friend who has a much, much less power than me.

But her astigmatism was severe

She was just as much as I could see.

1. Pure myopic people.

Because there is light in the water.

The refraction of the line and the distance between the swimming goggles and the eye are closer than the frame, so it is generally better to choose 50 100 degrees lower than the usual myopia (note: but do not wear a higher than usual degree, otherwise you will be dizzy underwater). For example, if your myopia is 500 degrees, you should choose 400 or 450 degree lenses when choosing swimming goggles.

As mentioned above, the minimum prescription for myopic goggles is 150 degrees, so if your glasses are less than 150 degrees, then we recommend that you wear flat goggles. If you have glasses with a prescription of 275 degrees, we recommend that you choose 200-degree swimming goggles, but if you have high requirements for corrective vision, you can choose to lower 25 degrees.

2. Myopic people with astigmatism.

You can divide the astigmatism by 2, add the power of myopia (myopia 1 2 astigmatism), and subtract 50 100 degrees accordingly, so that is the ideal goggle power.

3. People with different myopia degrees in both eyes.

For consumers with different myopia degrees in both eyes, the choice of power for the left and right eyes should also be different. The power selection method for each eye is handled accordingly in the above two cases.

After going to the ophthalmology department of a regular hospital, it is your best choice to follow the advice of the optometrist to get reasonable glasses.

There are myopia swimming goggles sold on the Internet, which can be of different degrees, ** quite affordable.

You should not choose too high swimming goggles, because there is a refraction of water at the bottom of the water, and the water plays the function of glasses, but astigmatism may need to buy a height to count a little (buy the height when there is a sun outside) (it can be a little lower indoors, no problem), it feels that it should not be too high, the right eye should be matched with a power of 500 degrees (about 365---425), and the left eye should be matched with a power of 475 degrees (about 345---410), in fact, there is no need to worry You are going to get myopia goggles, that's it, it's also a business to get myopia goggles, they should have some experience, look at the picture below, you can know how your eyes feel in the water (the answer is b.).c...f) Hope to help you.
