What Factors Will Make New Glasses Uncomfortable?
Some people maybe feel uncomfortable after changing new glasses. You will guess whether some powers are wrong or you are taken in ?
Here are several discomforts you feel probably:
1. Dizziness, nausea, headache
2. Eyes are tight, and there is pressure on temples or eyebrows
3. Things are out of shape when seeing from the edge of lens
4. When going downstairs, the stairs are deformed, the ground is uneven, and the screen becomes trapezoidal when looking at the phone
5. Pain in one or both eyes
6. Seeing far away is clear, looking near is tired and unclear, you need to look hard or blink to see clearly
7. Sometimes you see two things
8. When looking at things, there is glare and virtual shadow, things are not real
9. People can’t see clearly when looking straight at the level and can see clearly when lifting up the lenses or pull down the glasses a bit.
10. Degree of power is improved, but the vision is decreased
What factors will make new glasses uncomfortable? This includes the incompatibility caused by technical problems in the store, as well as the incompatibility caused by various wearing and the patient's own problems. After all, whether a pair of glasses is comfortable to wear or not is determined by a combination of many reasons, and there are problems in any link. It may cause discomfort.
1. The degree is not suitable.
Generally speaking, there is a problem with the optometry, the optometrist is not responsible enough, the technical level is limited, the optometry equipment has not been tested for a long time, the optometry environment is not good, too many interference during inspection, and the optometry time is too short, In short, the optometry is not accurate. For this kind of problem, the glasses should be replaced, not replaced.
2. Astigmatism.
Many friends report that the new glasses are deformed. The trapezoid shape of the mobile phone, dizziness and headache may be related to astigmatism, especially if you wear astigmatism for the first time, or wear low astigmatism degree before. Now degree the axis has been adjusted, it will cause discomfort. Most of these discomforts will disappear after a short period of adaptation.
3. Binocular balance is broken.
There is a difference between the dominant eye and the non-dominant eye. If you are wearing glasses, when you change the lens and adjust the power, it will break the balance of the eyes, which will cause discomfort, eye tension, swelling and pain in one eye, or even headache. There is also a situation where the degree of power is obviously improved, but the vision is decreased. These problems are often related to the breakdown of the binocular balance.
4. Binocular vision function problems.
Except seeing distant objects clearly, our eyes also need to see near objects, switching between distances, binocular monocular vision, fusion, etc. However, when our power increases too fast, or when we wear inappropriate glasses for a long time, there will be problems with our vision. If we change our glasses again, we need to re-adapt and re-adjust. During this period, one thing will become two, and it will be difficult to see close and things are easy to fatigue. These problems are often caused by poor adjustment ability or abnormal eye position. Most of them can be recovered by wearing glasses for a period of time, if the problem is serious, it needs to be recovered with visual training.
5. Pupil distance, pupil height problem
Once there is a difference in pupil distance, wearing glasses will definitely be uncomfortable. Because everyone’s pupil distance is different, but the frame size is same. If the pupil distance is too small, the optical center of the lens needs to be moved during processing and to make sure to move the optical center of the lens to the position corresponding to your pupil.
If the pupil height is wrong, it will also cause discomfort in wearing and can't see clearly. You need to push the glasses or press to see clearly.
6. Processing level
The pupil distance may be related to the inspection by the optometrist, but the processing aspect is the responsibility of the processor. Whether the processor carefully inspects the relevant parameters of the lens, whether the quality inspection is completed, and whether the processing is strictly based on the data. Whether the left and right eyes of the lens are reversed.
7. Adaptation cycle of special functional lenses
As the age increases, the accommodative power of the eyes decreases, and ordinary lenses can no longer meet the daily needs of eyes. Therefore, according to the recommendations of optometrists, some people choose progressive lenses. Such functional lenses with add have or do not have astigmatism area, which will affect the adaptation before wearing
Of course, the visual range of progressive films is getting larger, and the astigmatism area has been adjusted. However, when some people wear them for the first time, they will feel uncomfortable, such as such as feeling uneven when going up and down stairs, wavy feeling on the ground, need to turn the head to see the side and so on. Although these are not so good, the progressive lens solves the problem of eyes blurring at close range due to the decreased accommodation ability. Generally, the adaptation period of this kind of lens varies with age, from 1 to 3 weeks.
8. Wrong way of wearing old glasses
Many friends like to take off the glasses with one hand, or press and break the frame of the glasses when they are deformed and continuing to wear them. In fact, this is a very bad habit, especially for people with astigmatism. This will cause more serious problems, because when the frame is deformed, the distance between your glasses and other data are also changed. If you don’t adjusted your glasses well and adapted to the wrong frame data for a long time, it will become uncomfortable when you change new glasses because you cannot adapt to the new correct data, and even if all the data is correct, you will still be uncomfortable.
