Write to me and ask me if I should spend this money on a progressive film.
In fact, the price of Progressive is not too expensive now. If the economy allows, for people who are short-sighted and have started to suffer from presbyopia, I still recommend getting Progressive.
Because we now have a lot of needs for close-up viewing. You need to use a computer for work, and you have to look at your mobile phone from time to time. If you only wear a pair of ordinary glasses and then change to fancy glasses for close-up viewing, you need to wear ordinary glasses when looking far away. nearsighted glasses,
Not only is it cumbersome, it requires switching between two pairs of glasses to see far and near, and just taking out the flower and putting it on is basically equivalent to telling the people around me that my eyes are old and I am getting old, which is also quite embarrassing. Therefore, for those who are just starting to have presbyopia, they must understand the gradual progress.
But after all, most people are not familiar with Progressive Eyes (or spectacle prescriptions), and a pair of Progressive Eyes can cost thousands of dollars, and the cost of trial and error is indeed relatively high. If you want to get spectacle prescriptions to avoid pitfalls, you must understand the following common problems:
Trap 1. Do not do an eye examination, just get glasses
Solution: Find a professional institution or go to the ophthalmology department for an eye examination in advance.
After the age of 40, the risk of many eye diseases increases, such as glaucoma. Sometimes vision loss is not just a change in the degree, it may be a problem with the eyes itself.
Presbyopia is a decrease in the elasticity of the lens, and as we age, the lens may also become cloudy, known as cataracts. For people with obvious cataracts, progressive is not suitable.
There are also some people who may also have problems with eye position and have obvious strabismus. People with large degrees of strabismus are not suitable for gradual progression.
Therefore, before optometry, you must first go to the ophthalmologist to check whether there are other problems in the eyes, whether there is strabismus, etc. It is clear that it is only presbyopia, so let's consider the fitting gradually.
Trap 2. Don’t ask anything, just go to optometry
Solution: Fully communicate and tell the optometrist your specific situation and needs.
If you want to get a pair of progressive glasses that suit you, fully communicate with the optometrist and explain your needs are very important. Of course, you should do the same with regular glasses
Experienced optometrists or optometrists will also guide you to ask you some questions when fitting you. For example, I may ask you these questions for your reference.
1 Age: Generally speaking, for younger people, such as people in their 40s, the degree added under the progressive lens will be lower, and it is easier to adapt
2. Glasses wearing situation in the past: How long have you been wearing this pair of glasses now, and do you usually wear them? It mainly depends on whether the prescription of your previous glasses is suitable, and whether it will be difficult to adapt to the new glasses because the prescription of the new glasses has changed too much.
3. Ordinary eye habits and occupation: Evaluate your vision of far, medium and near, which will help you confirm more suitable parameters and choose products.
4. Have you ever worn Progressive? If you have, it will be easier to adapt. When choosing products, try to be the same or similar to before. If you have not worn it before, choose the appropriate product according to your eye needs, and try it on if you have the conditions.
Trap 3. Just take the prescription of the computer optometry strip and insert it for you to try it on
Solution: Check whether to use a comprehensive refractometer, and familiarize yourself with the general fitting process first
The computer optometry is only used for objective optometry. Generally, before the formal optometry, a computer optometry strip will be used to initially evaluate your degree, and then the comprehensive optometry will be used for subjective optometry, that is, to adjust and determine the final prescription according to your subjective feelings. mirror parameters.
The progressive glasses matching process mainly includes three parts: a priori find out the degree of seeing far away; determine the degree of addition, that is, the degree of seeing near; and try them on.
1. Check out the degree of seeing far
This process is the same as our usual glasses. There are a few important points. Friends who have had an optometry may also have an impression. Let me tell you what's going on.
1) The optometrist always asks you whether you can see red clearly, green clearly, or the same.
Why ask this? The main purpose is to confirm the spherical mirror. For ordinary people, it is the degree of myopia. If the red is clear, it means that the current degree is not enough; if the green is more clear, it means that the degree is higher; when the two are almost clear, it means that the degree is relatively appropriate.
2) Is there any line that looks different? This is mainly to confirm the axis of astigmatism.
3) More professional optometry will help you confirm the dominant eye.
Although we usually see things with both eyes, in fact we mainly use one eye, so when correcting, we must ensure that the dominant eye is clear enough, otherwise it will be uncomfortable to wear glasses.
The inspection of the dominant eye is also simple. Use your hands to spell out a diamond-shaped gap, place it in the middle of your eyes, and then select a target, first look at the target through this gap, and then close your left and right eyes respectively, you can see What is targeted is your dominant eye, and what you can't see is just your non-dominant eye.
2. Determine the degree of addition
The routine is to determine the degree of downgrade needed to see near 40cm, which is your presbyopia degree. Generally, the degrees of presbyopia corresponding to different ages are: 45 years old is about 150 degrees, 50 years old is about 200 degrees; 60 years old is about 300 degrees.
3. Try it on
According to your personal reading habits or special occupations, etc., adjust and confirm the final parameters through try-on.
Trap 4. The selected frame is not suitable
Solution: Result a more experienced optician to give you advice and try it on .
Some people especially like large frames, and some people prefer small frames because of their high degree, but in fact, you should choose a suitable frame according to your interpupillary distance and face shape. For progressive fitting, because the lenses gradually transition from top to bottom, and there are enough areas for far, medium and near vision, it is not always possible to choose a frame that is too narrow.
Trap 5: The selected lens is not suitable, only choose the expensive one, not the right one
After selecting the frame, it is necessary to choose a more suitable new product based on whether there is a history of gradual wearing in the past, specific eye needs, reading posture, and the size of the prescription.
Generally speaking, you need to get used to wearing it gradually for the first time. It is not that if you choose an expensive product, you will be able to adapt better.
Generally speaking, there are two more common designs for progressive: one is a balanced and rigid design, which has a wider far zone and a near zone, but the range of fancy distance is smaller, and the swimming is stronger, simple In other words, the field of view is relatively large, but it will be more difficult to adapt. The other is a balanced and soft design. The field of vision will be smaller when looking far and near, but the astigmatism is small, and the swimming is soft, so it will be easier to adapt.
There are also some products that take into account the advantages of the above two through the golden ratio design, which not only guarantees a large field of view, but also has soft swimming and is easy to adapt. Although it is not very expensive, it is very suitable for people who have a first-time fitting.
Trap 6. Only gave you glasses, but didn't tell you how to use them better
Wearing the right progressive glasses is not the end, especially for the first-timers, you have to learn how to use your glasses better.
I just put on Progressive in the early days and felt a little dizzy. Don’t worry, you can follow the principle of moving your head more and turning your eyes less, don’t worry.
What do you mean? That is, you sit indoors and wear glasses to look at it. When you look far away, your vision is normal. It is easy to enter the aberration zone, and it is easy to feel the volume. After the relatively static state adapts to the new glasses, it gradually transitions to walking, sports, driving and other scenes.
If you still feel that the dizziness has not improved after two weeks of wearing it in a sitting state, you may need to check again and communicate with the optometrist to see if the lens is not suitable, and find out the specific reason and solution.
By avoiding the above, you can basically get a suitable pair of progressive glasses for you. Believe me, when you really get used to progressive, you will sigh how convenient this visual experience is.
