I can’t see clearly after wearing new glasses

I can’t see clearly after wearing new glasses. Generally, we wear new glasses because the power of the previous glasses is inappropriate or damaged. To be honest, many people will encounter new problems after wearing new glasses. The following is about how to see clearly after wearing new glasses. Can't see clearly after wearing new glasses 1

This situation generally occurs for two reasons. The first is the performance of the adaptation period when just wearing it. This situation usually lasts within two weeks. The second is The situation is caused by incorrect prescription of glasses, so if your eyes need glasses, you must go to a regular hospital for a fitting.

Case analysis:

People with hyperopia usually have stronger adjustment ability. The definition of hyperopia is when parallel light rays enter the eye, and in an unadjusted state, the focus point of the light rays is behind the retina. The focus point must be on the retina to see objects clearly, so in order to see clearly, the focus point must be adjusted to the retina, so people with hyperopia usually have stronger adjustment abilities.

Astigmatism is myopia, which cannot be adjusted like general myopia, so astigmatism requires wearing glasses to correct it.

1. Can optometry test the adjustment ability of the eyes?

Yes. However, it is a special optometry. It cannot be detected by ordinary computer optometry and wearing an examination frame, and it takes a long time.

2. If the adjustment ability of the eyes is really poor, how long should I wear it before it becomes blurry?

Your inability to see clearly with new glasses has nothing to do with how well adjusted they are. The reason why you can see clearly when you are not wearing hyperopia lenses is because you have normal adjustment ability, but after wearing them, the lenses for hyperopia lenses relax your adjustment ability, making it impossible for you to adjust, so it becomes blurry. This is because you don't wear them. The reason why people with farsightedness can see clearly.

3. During the period of adapting to "adjustment ability", will it further affect my vision and make it worse?

No. Because hyperopia is innate, it will not decrease or increase after adulthood; but before adulthood, it may decrease due to external reasons. Because people with hyperopia use their adjustment power all the time every day, their eyes are prone to fatigue, and lenses for hyperopia relax their adjustment power, so wearing hyperopia lenses actually allows your eyes to rest. Since your

Your eyes are resting, so seeing far away will naturally be blurry. On the contrary, it will be easier to see close up (books, mobile phones,,,). In other words, your new pair of glasses is actually suitable for seeing near or far.

Therefore, if you want to see clearly at a distance, you must remove your hyperopia. When you really need to wear hyperopia glasses, it will probably be after the age of 50. I can’t see clearly after wearing new glasses 2

How long does it take to adapt to new glasses?

The adaptation time to new glasses usually takes one month. The eyes will have a process of adapting. When wearing new glasses, You will feel dizzy, and you may also experience symptoms such as dizziness, deformation of objects, and uneven ground in the short term. For first-time wearers of glasses, it may be due to the incompatibility of the eyes with refractive correction. If you still feel dizzy after wearing them for a month, you need to go to the hospital to see if the glasses are properly fitted.

1. Can you choose laser surgery after myopia?

Eye laser surgery is a very common surgical method in ophthalmology, and surgical treatment can be effective. It can improve corrected vision. However, if there are contraindications to surgery, the age is not reached, or there is active inflammation, general laser surgery is not allowed. After the surgery, the patient may experience dry eyes, glare, double images, changes in night vision, etc. Sequelae, some patients may develop complications such as keratoconus.

2. Can contact lenses be worn for a long time?

Wearing contact lenses for a long time can easily lead to eye fatigue, dryness, corneal hypoxia, etc. The resistance of the eyes will decrease, which will cause eye problems in the long term. Nerve paralysis. If contact lenses are attached to the eyeball for a long time, the nerve endings will be paralyzed, resulting in reduced corneal sensation.

Contact lenses absorb proteins, lipids, collagen, etc. in tears, causing them to deposit on the lens surface, breeding bacteria, and causing corneal edema, corneal neovascularization reactions, allergic reactions, etc. If you plan to wear them for a long time, you should clean your contact lenses daily to prevent the growth of bacteria and damage to your eyes.

New glasses halo

When wearing a new pair of glasses, some customers often report that the new glasses are uncomfortable and they always feel It feels awkward, uncomfortable, and feels different from the glasses I originally wore. As a result, many people have been wearing glasses that look very old and think they are quite comfortable and refuse to update them.

However, various technical indicators for testing new glasses, such as diopter deviation, optical center horizontal deviation and vertical deviation, axial deviation, etc., all meet the requirements.

What is the reason why abnormal reactions always occur after wearing new glasses? This phenomenon does not only happen to people who wear glasses for the first time.

Caused by the dispersion phenomenon

Some people are sensitive to the dispersion phenomenon, so they will feel uncomfortable when wearing ultra-thin lenses with a relatively low dispersion coefficient. For these people, they can only give up their appearance and choose lenses with a lower refractive index and smaller dispersion (which will be thicker). After all, health is more important~

The virtual image reflected from the inner surface of the lens Cause

This phenomenon is usually caused by lenses that are not coated with anti-reflective coatings. Because the reflected light reflects back and forth in the lens and then enters the eye, another very faint image will be produced, which will interfere with normal vision. In this case, just wear coated lenses instead.

The tilt angle of glasses

The tilt angle of glasses should be 8-15 degrees. If the tilt angle of the glasses is different from that of the original glasses or audition frame, 'If the tilt angle is different, you will feel uncomfortable.

Lens-to-eye distance

That is, the distance between the lenses and the eyes is incorrect. The distance between the eyes of a general audition frame is 12 mm, so the glasses you wear should also be 12 mm, otherwise you may not be able to see clearly or feel uncomfortable.

The spherical aberration of glasses

causes the distortion of vision after wearing glasses. Just like when you look at something through a convex lens, you will feel that the lines have become "concave"; when you look at something through a concave lens, you will feel that the lines have become "convex". In this case, it would be better to wear aspherical lenses.

Influences from other aspects

1. Influence from lens material

Due to the differences in refractive index, transmittance and other factors between light-white flakes, ultra-thin flakes, and resin flakes, etc. Due to differences in performance indicators such as optical power and Abbe coefficient, the wearing effect will be different for the same diopter. For example, some people feel dizzy as soon as they wear ultra-thin tablets, but they feel no discomfort when wearing white tablets, but white tablets are easy to wear.

2. The impact of the height of the nose pads of the spectacle frame on the visual effect. The height of the nose pads can directly affect the relative position of the optical center and the pupil and the distance from the rear apex of the lens to the cornea, which also affects the actual Vision effects.

For hyperopia corrected by positive lenses, the effective refractive power of spectacle lenses to the eye increases as the distance from the rear vertex of the lens to the cornea increases, and decreases as the distance from the rear vertex of the lens to the cornea decreases. For myopia corrected by negative lenses, the effective refractive power of the spectacle lens to the eye decreases as the distance from the apex to the cornea increases, and then increases as the distance from the apex to the cornea decreases.
