Deep myopia is really troublesome, I have been really perceptual from the eyes of the first year of high school to the current 500-degree myopia, I have astigmatism in both eyes, except for the eyes to see things is particularly hard...
In this case, it is best to wear glasses that are full-rim, as astigmatism can easily be affected by the slightest movement of the glasses. Your glasses may not be able to be cured if they are not in the right prescription or if the lenses are moved. In fact, LZ does not need to replace the lens within a month, the important thing is to pay attention to it, no matter how busy you are with work and study, you should let it rest when your eyes feel tired.
When the eye reaches a certain level of myopia, it is difficult for it to continue to deepen.
-
If you have never worn astigmatism lenses before, if you wear them now, there will be an adjustment period, and your astigmatism is on the high side, if you are in doubt, it is recommended that you go to another optician to check the axis position, if there is no problem, you do not need to change the lenses.
-
Hurry up and change, otherwise it's not good for the eyes, I used to be in the same situation as you, and then I went to change, how long did you wear the glasses before, if you wear them for many years, the power of the new glasses can't be increased so much at once, the eyes can't adapt, you can improve it by about 30 degrees to see clearly, I used to reduce the power of the good.
-
I guess it's because you don't have astigmatism at all, and the optician gave you the wrong optometry! You can go to the opticians next to the school to have it checked.
-
If it doesn't work, you still have to change it, just a pair of eyes.
-
There are two possibilities for new glasses to feel a little archy, one: your lenses have astigmatism, and two: the glasses that are processed are too long or the curvature of the glasses frame is relatively large. It's a bit uncomfortable to see, and it takes about 5-7 days to get used to the new glasses.
-
First of all, it is important to understand that modern technology cannot replicate glasses with different frames of the same power. In addition to the power, there are also important factors such as visual field, spectacular eye distance, optical centroid distance, and inclination, all of which cannot be completely consistent. Even the power (top power) cannot be the same, you must know that according to the national standard, 913 is also called 950 degrees, and 962 is also called 950 degrees, how can it be the same?
You calculate how far the difference is. If it is more than 150 degrees of astigmatism, the axial deviation of 2 degrees is unqualified glasses, which is stipulated in the national standard. What's more, it is impossible to make the old mirror without a little deviation, and the old deviation plus the new deviation is too much difference, so there must be a problem with you according to the original mirror, and all kinds of discomfort are the rejection reaction generated by the body.
Adaptation problems do exist, but forced adaptation only masks the problem, and in short, optometry is necessary for changing glasses.

If the power of the eye has affected daily vision, then you need to go to the hospital for accurate refraction, and then choose the right prescription, lenses and frames. For myopia, in addition to wearing suitable glasses, you also need to pay attention to:
1. The time of close eye use should not be too long, every 40-50 minutes, you should take a little rest for 3-5 minutes, and look into the distance to relieve visual fatigue.
2. Read and write, play with the computer, maintain a correct posture, the height of the table and chair should be appropriate, and the distance between the eyes and the reading materials should be about 33 cm.
3. Mix whole grains, meat and vegetables, eat more vegetables and fruits, and don't eat partially. Lack of vitamins in food is prone to night blindness and dry eye disease, and lack of trace elements chromium and calcium in food makes it easy to suffer from myopia. In addition, it is also necessary to pay attention to regular supplementation of eye vision nutrients, not from the nutrients required by the eyes, enhance the anti-fatigue ability of the eyes, and better protect the eyesight.
Fourth, when reading and writing, the light should be moderate, not too strong or too dark, and the light should come from the left front, so as not to obstruct the vision of the hand shadow. The light should be soft, if it is incandescent, it should be between 25 and 40W, and it is not recommended to read in the sun. Because the intensity of light has a direct impact on pupil dilation, too strong light will increase the intensity of eye accommodation, aggravate the intensity of eye labor, and it is easy to cause myopia after a long time.
Generally, desktop lamps should be less than 40 watts.
5. Avoid reading while walking or reading in a walking car. Because the carriage is shaking, the body is shaking, and the distance between the eyes and the book cannot be fixed, the burden on the glasses will increase. Often, this is likely to lead to myopia.
6. Actively participate in physical exercise to enhance physical fitness. As the eyeball follows the target, the ciliary muscles continue to relax and contract, and the synergistic effect of the extraocular muscles can increase the blood perfusion of the eye, promote the metabolism of the eye, and thus reduce eye fatigue. Moreover, the quality of physical fitness is also closely related to the occurrence of myopia in children.
Malnourished and weak children are prone to myopia.
7. Insist on doing proper eye exercises. By massaging the acupuncture points around the eyes to enhance the blood circulation of the eye socket, improve neuronutrition, eliminate the excessive congestion in the eye, and achieve the purpose of relieving eye fatigue, it is conducive to the prevention and treatment of pseudomyopia in adolescents, and is a good way for adolescents to self-care their eyes.
8. Eat less candy and high-sugar foods. Too much sugar will produce a large amount of acidic substances in the blood, and the acid will combine with the salt in the body, especially calcium, resulting in a decrease in blood calcium, which will affect the toughness of the eye wall, make the eye axis easy to elongate, and promote the occurrence and development of myopia.

Of course, you've gotten used to your glasses, and the prescriptions of the past should be different from the ones you have now, and your glasses haven't gotten used to them
Maybe your new glasses are very different from your original prescription, and if you don't want to wear glasses, go for laser surgery
It's better to do it early
-
There are several possibilities: 1: Whether the spectacular distance (the distance between the posterior surface of the lens and the apex of the cornea) is changed.
2: Whether the interpupillary distance of glasses or the interpupillary distance of one eye has changed. 3:
Changes in shaft position are also possible. 4: Lens quality problems.
Wait. If you don't understand, ask me again.
-
What is the reason why I can't see clearly when I wear the glasses I just weared, and my eyes are uncomfortable? The experience of the opticians tells you!
-
Do you have this phenomenon when you try it on at an optician? The new glasses have just been fitted with two or three days, and the adaptation cycle is normal. Do you say that wearing the previous one has been restored, is it back to normal size, sharpness?
-
It's good to get used to it, just like when I was a child.
-
It is probably caused by the change in the distance and inclination angle between the glasses and the eyes of the new glasses and the old glasses, and the pupil height is different from before.
It is recommended that you go to the optical store where you have glasses and ask them to adjust it for you.
-
First of all, the adjustment of the frame will not change your interpupillary distance, the interpupillary distance of the person is a fixed value, it may be that the distance between your glasses frame and the eye has changed, so that the relative glasses power changes. In addition, the brand of spectacle lens, refractive index, Abbe number is different, and the astigmatism and aberration of spectacle lenses are different, which is also related, but it will generally be automatically adapted.

Hello, please don't wear strict glasses to see a centimeter wide line, only glasses have been with 4 years, please ask the question in**Thank you!
-
New BAI glasses and power change are possible.
DU can cause dizziness, visual distortion, etc. The degree of adaptation will vary according to the adaptability of each DAO individual.
However, your prescription doesn't change much, and this discomfort shouldn't last long. Wear them for a week (if wearing new glasses is really uncomfortable, you can reduce the wearing time appropriately). If you still can't get used to it, it is recommended to go to the place where the glasses are prescribed to check the prescription.
There is also a situation where there are problems with the processing of glasses, such as interpupillary distance, pupil height, astigmatism axis, etc., which may have deviations in processing, but the state has clear standards for these deviations. It is best to check whether the glasses are processed or not.
If it is a processing problem or an optometry problem, the optical store will replace the lens for free.
-
It may be that your prescription has deepened too much at once, and your eyes can't adapt to the glasses that are matched according to your actual prescription. Generally, inserts will be made before the glasses are fitted, and the final glasses will not be fitted until you are used to the appropriate prescription.
-
The new glasses need to be used to, and it will be fine in two days! I've been like this since the beginning, I've encountered it.
-
Obviously, there is something wrong with the eyes.
-
Is there something wrong with the glasses? You can take it with someone else.
-
Hello! This is your discomfort with the new glasses!
But did you have astigmatism when you measured it?
If the measurement is accurate, it will not have a bad effect on your eyes!
-
My friend, I'm also short-sighted.
1. The degree of myopia decreases.
2. The quality of the lenses is not good.
3. The brightness is strong in the place you are.
4. Your retina has not yet adapted to the new glasses.
You need to get used to it slowly.
-
Friend: 1: Do you wear glasses with the same prescription as you used to be?
If it's different, then you have to look at how much your corrected vision is. For example, if you can see the eyesight, then the glasses you wear are yes, then you can adapt to this for a few days. If you still can't get used to it, you can reconfigure a pair of glasses with a lower prescription and you can see a vision of 1 0
2: Did you wear aspherical lenses before If so, it depends on whether you are wearing aspherical lenses now If it is not aspherical, it is normal for such a phenomenon to occur You can go to the store where you have glasses to see
3: See if your vision is balanced Let's say your vision in both eyes is: Right eye Left eye can achieve balance of vision in both eyes.
The glasses you wear now are. Count the right eye and the left eye, then the new pair of glasses will not be able to achieve binocular visual acuity. Then it is normal for such a phenomenon to occur.

Does your child's glasses feel smaller? Is it normal, thanks.
is normal, the possible reasons are:
1. The prescription may be much longer during this period. >>>More
The new glasses look blurry in the near distance??
Dear, you are obviously a problem with eye adjustment, you try it, take your glasses a little farther away and wear them to see if you will not see clearly, I am confident, you will definitely see clearly. >>>More
This situation is naturally not good for the eyes, one eye is clear and the other eye is blurry, which can easily lead to the uncoordinated sight of objects in both eyes, and the objects seen by both eyes are not well integrated in the brain, and they will feel difficult and unable to adapt. In the long run, the left eye will be overused, and the fusion and stereoscopic vision of the two eyes will not be well established. It is recommended that you go to a regular optician. >>>More
Cooking headphones is just a way to soften the diaphragm, and the effect of this method is limited and subtle. >>>More
Big brother, first of all, you are using the wrong medicine, colds are caused by viruses, amoxicillin is an antibiotic, and it is ineffective against viruses. This is the misuse of antibiotics and can lead to bacterial resistance. >>>More
