I don t know how to wear glasses online

After getting the glasses list, let's first take a look at it and divide it into two parts, where the part marked with r represents the right eye, and the part marked with l represents the left eye. Each part has three groups of numbers, among them: the first column of numbers is represented by s, which represents the degree of our myopia or farsightedness, if the front of this column of numbers is a positive sign, it means farsightedness, if the front of this column of numbers is a negative sign, it means that it is myopia, and the numbers above represent the degree, for example, positive represents one for farsightedness, and negative for two.

The symbol in front of it still represents myopia or hyperopia, for example, positive, representing 150 degrees of hyperopia, and negative representing one....

Hello, I don't know what kind of data do you give to glasses, go to a regular professional optical store to optometry, clearly say that only optometry is not glasses, it is best to --- a fair transaction to charge, and then go to **Find Chen Qifengs

You're kidding, if you don't have glasses without testing, how can it work? It is very important to wear glasses, you must go to the ophthalmology department of a regular hospital to check the optometry, and then wear genuine glasses, otherwise it will hurt the eyes.

To tell the truth, online glasses are really bad for the eyes, not to mention that they can't be fit, and there may not be after-sales service, and although they are cheap, the quality is not guaranteed!

Personally, I recommend that you go to the optical store to buy, it is best to buy the best lenses, which is also beneficial to the eyes, and I personally think that many brands are good: Schumann and Mingyue are very good! Hope it helps!

The R and L on the list of visual acuity represent the right eye and the left eye. "Ten" stands for farsighted glasses, "—stands for myopic glasses, and D stands for power. The details are as follows:

Unaided visual acuity: Unaided visual acuity is the eye's own vision, which is indicated by letters. r：

Unaided visual acuity in the right eye, L: unaided visual acuity in the left eye. Corrected visual acuity:

Visual acuity after wearing corrective glasses, and visual acuity should reach 1.0 after wearing corrective glasses. The diopter is denoted by " ", " which indicates farsightedness. "- indicates myopia.

Criteria for judging myopia: the degree of myopia is greater than 50 degrees of myopia, and the value of the column is greater than 50d, 50d-300d is mild myopia, 300d-600d is moderate myopia, and more than 600d is severe myopia.

Criteria for judging hyperopia: hyperopia greater than 50 degrees is farsightedness, and the "" column on the vision examination sheet is greater than 50d, 50d-300d is mild hyperopia, 300d-600d is moderate hyperopia, and greater than 600d is severe hyperopia. The difference between 50 degrees of myopia and 50 degrees of hyperopia is the normal degree of vision.

Through the data of vision examination and optometry examination, the visual acuity condition of the eye can be determined, and whether the eye vision meets the standard, whether it has myopia, astigmatism and farsightedness. The value of the vision test slip is used to determine whether glasses are needed to correct vision.

To open a brand glasses franchise store, you should be familiar with the local market environment and consumer demand, and then choose a good glasses brand, and choose a professional team to develop it, so that the reputation and quality are guaranteed.

There are professional instruments that can measure the power of glasses, and it is difficult to get accurate data by visual inspection. Myopia glasses are concave lenses, and things can be seen through the glasses to shrink, and the more obvious the shrinkage, the higher the power. Farsighted glasses and reading glasses are convex lenses, and the ** seen through the eyes is magnified, and the higher the power, the more obvious the magnification is seen, and at the same time there is a certain degree of distortion.

If there is astigmatism in the lens itself, the image seen in the vertical and horizontal directions is of different length, and you will need to go to the hospital to wear glasses.

R or OD on the hospital optometry sheet: for the right eye, L or OS: for the left eye, the degree is expressed in D, and 1:00D is commonly referred to as 100 degrees.

In addition to this, a positive sign on the optometry sheet indicates farsightedness and a negative sign indicates nearsightedness. Usually pay more attention to the safety of children's eyes, to avoid children are ignorant and playful to irradiate their eyes with lasers, which is very harmful. For the sake of the child's future, you should protect your child's eyes, and you can also let your child do eye exercises.

Hope it helps.

Questions. <>

This is what the doctor gave ().

Then because of some circumstances I can only dictate to the optician, I changed how to say ().

l is left. r is right.

The optometry sheet of myopic eyes mainly includes three parts, the front part is usually marked with a capital English letter S in front, which means that the spherical lens means the degree of myopia, if it is written in front, it proves that it is 100 degrees of myopia. After this is the capital English letter C, which represents the cylindrical mirror, that is, the degree of astigmatism, if there is astigmatism, a number will appear in this position, and there will be a degree behind this number.

The determination of the power of glasses needs to be measured with a degree focus, usually the letter R represents the right eye, the letter L represents the left eye, the letter DS represents the spherical lens, and the difference between farsightedness and myopia should also be included, such as the minus sign represents myopia, the plus sign represents farsightedness, if it is DC, it represents astigmatism, and between 0-180 degrees represents the axial direction. If you need to determine the power of glasses, you can go to a professional hospital or optical store to measure, if you need to replace the glasses, you need to re-measure the prescription, and the final prescription of glasses should also be determined according to the results of optometry.

Hope it helps.

Questions. So what do you mean by my astigmatism?

I don't know too much here.

You can send it directly to the optician.

Questions. Just, the optician from Japan said, I'm going to send this to ** and then. Said he couldn't read.

I'll give you a suggestion.

You go to JD.com or ** and find an optical store.

Customer service asks.

I don't know about it, I don't understand.

Questions. Soga, line.

<> eye examination is usually right and then left, with the upper R being the data of the right eye and the lower L being the data of the left eye. The first column of numbers is the degree of farsightedness or myopia, "+ represents farsightedness," - represents myopia, and it is generally measured three times to take the average. The second column is the astigmatism, and the third column is the astigmatism axis.

Whether the online glasses are accurate depends on the specific situation. First, whether the optical store is professional, the technical level is uneven, and some stores are purely small workshops, and the technology is not guaranteed. The second is whether the data you report is suitable, such as myopia.

Power, pupillary distance, etc., have a great impact on the wearing of lenses. The third is whether the material of the spectacle lens is ***, and the difference has a great impact on vision correction. Therefore, it is recommended to choose a physical store for optometry and wear the appropriate glasses according to the actual situation, so as to protect your eyesight.

Glasses on the Internet is still not very reliable, children must go to a regular hospital for optometry, wear glasses, this is the most correct, don't figure a ** low, children's eyes are very important, must go to a regular hospital is the most correct, don't believe those statements on the Internet.

As long as you give the right prescription, there should be no problem with the prescription of the mesh lens.

As long as it's not a special degree, the general power has nothing to do with **, so if they don't do it accurately, it won't do them any good. There must also be after-sales.

If it is estimated by a computerized refractor, there will be an error, because the automatic computer refractor still has an error, which is only known to the optical store, and the accurate prescription can only be obtained after the lens audition. The prescription of computerized optometry cannot be used as a basis for dispensing glasses.

There will still be some inaccuracies in online optometry, because the human eye may change the power of the eyes in different time periods, and I may change the power of the eyes under different learning levels, so try to choose some instruments with higher precision to minimize these errors.

It is best not to match glasses online, but to go to the physical store to match some high-quality products, at least there is quality assurance;

Opticians can take prescriptions for free and then don't have glasses, which is generally not feasible.

Most optometrists.

Free refraction, and finally tell the degree of crack imitation void, but will not give the refraction data. Because they know that the data must have to go somewhere else to get glasses. If you go to a physical store to buy glasses, you will generally have optometry, and if you want optometry data, then you must want to get glasses online.

Optician's refraction accuracy.

A large part of it has to do with optometrists, optometrists have to receive a lot of customers every day, if they want to buy glasses, then she will be happy, if she just wants to optometry, she will definitely not give optometry well.

In this case, the eye data she told is likely to be fake. Of course, this can't be generalized, there are still some optometrists, even if they don't buy glasses, they will still give a very accurate test.

Yes, but it mainly depends on the requirements of the optician, and usually when you get glasses, the optician will perform an optometry first and then decide on the right lens according to the prescription.

If the store has a free optometry program, you can go to optometry for free. However, if it is to determine the true power of your eyes, it is recommended to go to a professional and regular optical store for optometry, if you have myopia or other vision problems after optometry, it is necessary to pay attention to it and correct it in time.

If the eye has myopia or other vision problems, it is necessary to correct the bad eye habits when attacking, but the refractive problem of the eye can not only be found through a kind of vision, but also need to be refraction, optomy, and even a comprehensive refractor for a detailed examination to clarify the problem of refractive error in the eye. It is recommended that you choose a regular optical store for a detailed eye examination to obtain systematic and comprehensive examination results. If you need glasses, you should also choose a regular optical store, don't choose blindly.

If you invest in opening an optical store to start a business, you should predict in advance in terms of capital budget, how many square meters of optical store needs to shoot the approximate amount of funds, and at the same time, you also need to budget to account for a rent and daily expenses of your own store, so as to give yourself the maximum capital turnover space.
