Optometry is not only a technology, but also an art, because
It has almost no fixed model and measurement standard, although glasses are basically.
Positive and negative cutting, convex and concave flat, but the recipient is thoughtful and psychologically active.
People. Everyone's age, sex, physique, eye adjustment, refraction of refractive stroma
Force, retina, visual cells, visual pathways, visual centers, etc. The nature of work, work
Working hours, living conditions, living and working habits, eye habits, vision requirements
Different requirements, so no matter how high the optometry technology is, these factors are not considered (especially
Is a psychological factor), glasses may not be suitable. 1897 strategy-
Tony did an experiment on himself. He put on a mirror and got on the horse.
I saw that everything outside was upside down and it was difficult to walk, but he insisted.
After wearing it for a while, the object I saw came again and the symptoms disappeared completely.
Yes But when he took off his glasses, he saw the object upside down for a while.
Suddenly back to normal. In fact, this is the role of visual psychology, visual psychology
In harmony with the proprioception system, so visual psychology can be exercised and
Experience, which requires our optometrist to have an optometry prescription.
Fully understand and fully estimate that glasses will be produced when they are worn in front of patients.
What kind of prognosis has a prognosis for patients. For example, patients with high astigmatism
Wearing glasses for the first time, tell them that they may have visual distortion and stick to it.
Wearing it will make this feeling disappear. The forecast should also include the possibility of wearing glasses
Other discomfort symptoms that may occur later, this situation is normal, the
How to adapt, how long this symptom will last, etc. Only in this way can we.
It will make patients psychologically prepared for adaptation and will cooperate with adaptation. Especially progressive multifocal.
It is more important to order glasses and teach patients to use them correctly.
Without this prediction, once the patient has uncomfortable symptoms,
No matter how to explain it, patients will get suspicious and think that the optometrist is shirking.
Responsibility, thus losing the trust of fitting personnel and optical shops [1]. So, one
The optician must have a high professional level, skilled technology and good quality.
Quality, can be competent for this job.
1 the influence of vision on psychology
When people see beautiful things, they will feel happy, while they see disgusting things.
There is a boring heart, in the night sky without reference, if there are clouds, it will
See the stars or the moon through the clouds, but if you use branches or other static cracks.
As a reference, you will see clouds, not stars or the moon.
Light passes through, so the former is an optical illusion and a visual psychological error.
Judgment. Under a tall and isolated building, if you look at it, you will have a building.
The illusion of leaning to one side. If you look down from above, this feeling will
More obviously, if you close your eyes, this feeling will disappear and you will often work at high places.
People don't feel this way. The so-called "once bitten, twice shy" is due to
Because the bitten person sees the snake that bit him, he will have "fear" about the snake-shaped well rope, such as
He didn't see the snake that bit him, so he wouldn't be afraid of the well rope and "look at the plum to quench his thirst".
People who haven't eaten plum and don't know plum can't quench their thirst when they see plum.
Yes, these two idioms are the true portrayal of visual psychology. The optometrist is optometry.
In the process of writing, we often encounter some problems caused by visual psychology. Whether there is astigmatism.
The vision was distorted before correction, but the patient did not feel any change except blurred vision.
Shape, this is because it lived for several years, more than ten years without even wearing glasses.
For decades, I have been living in the cognitive experience of things. Once I put on my glasses to correct it, I am
The improvement of vision produces visual distortion at the same time, because it changes the original.
The illusion caused by that deformed habit.
1. 1
A 67-year-old woman's optometry result was -20.50ds/- 1.00dc× 90.
(r), -20 00DS/- 1 50DC× 85 (L), corrected visual acuity was 3.9.
(0.08), we tried-10.50ds (R) and-10.00ds (L) for the first time.
Its main complaint: "No, it's too clear and too bright for me to accept". Blurred dozens.
Years, a little clearer, but not used to it; A 19 middle school student, optometry.
The results are-3 00ds/-1.25dc×180 (r), -2 75DS/- 1 00DC×.
175(L), but the best corrected vision is 4.8, and the original mirror is -2.50ds/
Audition time-1.25dC× 95 (R), -2.25dS/- 1.25dC× 85 (L).
When the cylindrical mirror is adjusted according to the original axial position, the best corrected vision is 5.0 2. Through computers and
Retinoscopy and optometry confirm that the cylindrical axis is horizontal, but the corrected vision is not good, and the patient
He also reflected discomfort, made glasses for him according to the horizontal axis, and explained his previous
The glasses were wrong and the patient agreed to adapt. After wearing glasses for two weeks, the corrected vision was
5.0+3, and no discomfort. There is a big difference between the optical center of some original mirrors and the actual pupil distance.
Older people, the younger they are, the faster they adapt after the change, and some patients refuse to adapt, then
Just a little adjustment or matching according to the original mirror. There are many patients who match for the first time, in the process of trying on.
Moderate, reflecting discomfort symptoms such as dizziness and acid eyes, reducing luminosity and correcting vision.
When the intensity drops to 4.7, it is also dizzy and uncomfortable, but it should be adjusted back to the first fit.
Number, and told me that "the adjustment is not dizzy, it is adjusted to the lowest", and the result is true.
I'm not dizzy. Theoretically, this is not the case when the difference of anisometropia exceeds 250 days.
He can see one eye, but he has myopic anisometropia with a difference of 600 days.
Compared with patients with mixed anisometropia whose phase difference is 100d, the glasses are comfortable to wear.
These are all after a detailed examination of combination, fusion and stereoscopic vision during the audition.
Only prescription glasses are given, and the patient is informed of the examination purpose and fitting method.
The patient was willing to cooperate, so the installation was successful. Textbooks record that the principle of opticians is myopia.
Is the lowest degree of the best vision (including myopic astigmatism and compound myopic astigmatism), far
Vision is the highest degree of best vision (including hyperopia astigmatism and compound hyperopia astigmatism).
But this principle can't be applied to all opticians, for example, higher height.
For the person who wears glasses for the first time, it may be unacceptable to give enough light at one time, so the light intensity can only be reduced at different times, which is not acceptable.
According to the best vision [2].
2 discussion
Eyes with higher diopter should be corrected several times when matching glasses, and finally they will be double light.
Uneven and balanced eye vision, improving vision; Optometry should be accurate and the purpose of audition should be curved.
People with poor light not only improve their eyesight, but also feel comfortable. After wearing glasses, they won't feel dizzy, and they can see things the same.
Form, not out of shape [3]. After repeated trials, it is generally necessary to audition to determine the prescription of glasses.
About 30 minutes. If you feel unwell, find out the reason as soon as possible; When you audition, ask about your past clothes.
Mirror condition, especially the change of astigmatism axis, is very important for opticians, and some people are used to it.
The axial position of glasses, so generally do not adjust, so as not to adapt to the wearer; correct
Myopia, it is best to correct the vision with low degree as far as possible; Try to accept hyperopia.
The degree of correction of the best vision, and determine the diopter according to the age, such as companion vision.
Try to wear enough degrees when you have esotropia; Common causes of unsatisfactory corrected vision are
High myopia, high hyperopia, high astigmatism, etc. Because the degree is too high, the fundus has
Changing and correcting vision is often not ideal. Amblyopia is the main reason to correct the poor eyesight of teenagers.
Therefore, patients with amblyopia should be required to strengthen their use after wearing enough degrees.
Eye training to promote the recovery and improvement of vision; Mydriasis optometry excludes labor.
Subjective factors, excluding pseudomyopia caused by ciliary muscle tension, reflect.
The true diopter also provides reliable data for the next audition, so it is 12 years old.
The following children should adopt mydriatic optometry; For monocular myopia or binocular anisometropia
Old people can consider wearing contact lenses. In a word, the purpose of optometry is
Make ametropia people improve their vision, wear comfortably and achieve the best corrected vision.
If the corrected vision cannot be improved, the reasons should be further searched [4, 5].
