Are optician optometry all free, which is the right optician optometry or hospital optometry?

Not confident enough in their own optometry level.

The optical store gives you optometry data, in fact, it is equivalent to not giving it, because there is no guarantee that the frames you wear online will suit your face shape, whether the frame size is suitable for this luminosity, and because the online fitting masters do not have high-tech optometry and assembly equipment.

There are four parts to the process of fitting glasses: an accurate optometry, choosing a frame, lens thickness, and adjusting the glasses.

1. Accurate optometry sheet. The data of the optometry sheet includes the degree of myopia or farsightedness of the left and right eyes of the optician, as well as the interpupillary distance of both eyes. If there is astigmatism, the degree of astigmatism and the axis position of the astigmatism are also required.

2. Be cautious when choosing a frame. The shape of the spectacle frame is very important, in principle, a square or rectangular face is suitable for an oval or rectangular frame with a certain curvature, a round face is suitable for any shape of frame other than a circle, and an oval or melon seed face is generally suitable for any shape of frame. Frame size is also important, and only those that fit your size are more comfortable.

The larger the frame, the heavier the weight, and the higher the requirements for the refractive index of the lens.

3. Whether the glasses are suitable for you depends on the thickness of the spectacle lens. The thickness of the lens is directly related to the refractive index of the lens. The higher the refractive index at the same power, the thinner the lens.

The refractive index can be selected within 300 degrees, the refractive index can be selected at 300-500 degrees, the refractive index can be selected at 500-800 degrees, and the refractive index can be selected above 800 degrees74 refractive index.

4. After the glasses are selected, you also need to make adjustments according to your face shape when you take the glasses, such as whether the nose pads fit the bridge of the nose, whether the hooks of the temples are just hanging on the ears, whether the glasses are chucked, etc., so that the glasses are adjusted to be more comfortable to wear.

To open a glasses franchise store, you must choose a strong brand, so that the franchise can be guaranteed, so that entrepreneurs can rest assured, and the success rate of opening a store will be high.

No, some are free and some charge money. But if you're sure to buy his glasses, it's definitely free optometry.

Optician's refraction is accurate.

It is a mistake to think that hospital optometry must be good in the first place. Because the doctors in the hospital are mainly eye disease examinations**, and optometry and glasses are mainly corrective. Eye disease examination and optometry are two different things, each with its own specialty.

At present, except for a few hospitals with optometrists with excellent optometry skills, the optometrist skills of many hospitals may not be better than that of some optometrists in optical stores.

Optometry precautions in opticians.

Medical optometry glasses generally cost dozens of yuan, which is more expensive than ordinary optometry glasses, the reason is that ordinary conventional optometry refers to the optometry in general optical stores, and its purpose is only to let refractive people see objects clearly, and the operation methods and steps are relatively simple. Medical optometry must first have a high-precision, high-cost comprehensive optometry.

Secondly, the optometrist is required to be an optometrist who is familiar with clinical ophthalmology and optometry. Professional "medical optometry" is a complex medical process. As a medical act, medical optometry must be performed to ensure accurate glasses and a pair of glasses that are both comfortable and can play a role in health care.

Optometry is to check the concentration of light after entering the eyeball, and it measures the degree of convergence and dispersion between the examined eye and the emmepic eye based on the state of the emmetropic eye. Because many people will almost get involved with glasses in their lives, optometry is one of the most basic, most commonly used but important jobs for optometrists, so as far as the term optometry is concerned, it is very familiar to both ophthalmologists and ordinary people in social life.

There are many methods of refraction, which can be divided into dilated refraction and small pupil refraction in terms of whether or not to make the eye adjust to rest. From the method of refraction, it can be divided into other refraction and subjective refraction.

As far as optometry equipment is concerned, in addition to conventional equipment such as optometry lens boxes and ophthalmoscopes, there are also computerized refractories and comprehensive refractors. The computer refractor has been over-promoted, but through a large amount of data analysis, although the computer refractor is the crystallization of high technology, it can only make a preliminary screening of the refractive state, and can never use its results as the standard of refraction.

The comprehensive refractor integrates a variety of inspection functions, since the birth of the early 20th century, it has been continuously improved and developed, it can not only check the diopter of the spherical lens, but also correctly detect the astigmatism and astigmatism axis, in addition, it can also make correct judgments on the eye position, adjustment and binocular monovision function, etc., and master and use the comprehensive refractor, which is the key measure to improve the level of optometry.

Hello, it is a pleasure to serve you and give you the following answer: Optometry is an important part of the optical store and a key step in determining the prescription of glasses. Generally speaking, the optometry service of the optical store is between 100-200 yuan, and the specific ** can vary according to the different optical stores.

The main steps of optometry are: 1. Check your eyesight: First, the optometrist will check your eyesight to determine if your vision has changed and whether you need to change your glasses.

2. Measure your eyes: Next, the optometrist will measure your eyes using a professional instrument to determine the power of your eyes. 3. Determine the power of glasses

Finally, the optometrist will determine the most suitable prescription for your glasses based on your vision and the power of your eyes. Optometry is a technical process that requires a professional optometrist to ensure that your glasses are properly prescribed.
