The significance of visual training for visual training

1. Know our eyes.

The anatomy of the eye is the same as that of a camera. We also have a very fine organ in our eyes, the lens, which is like the focuser in the camera, doing countless fine focusing movements every day to ensure that we can see objects at different distances at any time.

2. Why do eyes get tired?

The lens is the focuser of our eyes, and it is the muscles that drive the focus of the lens, just like the muscles of our arms and legs.

For example, if you sit every day, after 3 hours, you will feel backache and back pain, which is your lumbar muscle and back muscle fatigue. Similarly, after 3 hours of computer use, your eyes will be tired, we call it eye fatigue, it is the muscle of your eyes that focuses on the movement - the ciliary muscle is tired, it can't produce effective movement, your eyes can't focus.

3. Symptoms of eye fatigue.

Headache and fatigue after reading and working in close proximity;

Inability to concentrate, low efficiency in work and study;

slow reading speed and inability to remember what you have read;

difficulty transcribing notes from the blackboard;

It is not clear to see far after looking near for a long time, and it is not clear to see near after looking far away;

eye fatigue, eye pain, eye soreness, eye dryness, discomfort, double vision after reading;

text moves, jumps, swims, or floats on the paper when reading;

Occasionally, it is "serial" when reading;

Myopia is growing too fast.

4. How to alleviate eye fatigue.

Eye strain is caused by fatigue of the ciliary muscle, which the eye is responsible for regulating, or a long-term state that causes the lens to not focus quickly.

Since focusing is driven by the movement of the ciliary muscles, the strength, speed, and amplitude of the muscles can be exercised. Remind everyone that you can effectively train the ciliary muscle, change its working state, increase muscle strength and movement speed and amplitude, effectively improve focus, and make the eyes less strained.

Visual training is the most effective way to improve accommodation and reduce visual fatigue.

Fifth, visual training to adapt to the population.

Student; computer users;

People with frequent eye fatigue;

prolonged proximity workers;

Driver; Those with early presbyopia symptoms;

those who have difficulty reading at close range;

Excimer postoperative, those who are not comfortable to read closely;

Those who are tired of wearing glasses.

6. Symptoms that can be improved by visual training.

symptoms such as blurred vision, post-visual headache, tired eyes, double vision, blurred near reading, or fatigue;

After long-term close work, or when nervous, symptoms such as blurred vision, headache, and double vision appear.

There is a very slow way to see objects clearly, especially when there is a change from near to far or from far to near, such as looking near and then looking at a distant place, you need to stay for a while to see clearly, and you have to stay for a while to see far and then near to see clearly, resulting in visual discomfort and a decrease in effective visual acuity;

When driving for a long time, seeing objects will be clear and blurry, and the eyes will be tired;

Myopia is growing rapidly.

Exercising visual ability can be trained with the help of training tools, visual training home training products mainly include double-sided mirrors, vision cards, alphabets, scatter balls, collection cards, slit ruler trainers, etc. The training room consolidation training products mainly include lifebuoy cards, red and green playing cards, range series, double-layer training brackets, etc.

During the training, let the trainer experience the feeling of tension and relaxation of the eyes, and the difference between the convergence and spread of the eyes. The emphasis is on quality rather than quantity during training. Create a realistic training plan and goals, but with some flexibility.

Make the trainer aware of the following feedback mechanisms:

Positioning: Indicates the fused image in the visual space.

Parallax: Convergence and dispersion change as the fused image moves Floating: a part of the phenomenon of near-small and far-large.

Sparkle: color blending, red and green.

Blurry: When using inappropriate accommodations.

Double vision: When the eyes are not aligned.

Inhibition: Almost all visual training products have inhibition cues.

Proprioception: the feeling of gathering and spreading.

Visual training, also known as vision, is through optical, psychological, physical and other methods, by professional doctors according to the specific visual conditions of patients, a series of training programs are formulated from person to person, which can significantly improve vision, enhance visual skills, and develop visual potential, so as to achieve the purpose of visual fatigue, eye movement disorders, dyslexia and other binocular vision diseases, and achieve the purpose of comfortable and coordinated use of both eyes.

Purpose of Visual Tracking Training:Improve students' ability to divide their attention; When the teacher walks around the classroom and lectures, the students can also concentrate and follow the teacher's train of thought without being distracted by moving objects.

Skill application: When the teacher walks around the classroom and lectures, students can both look at the teacher walking around and focus on what the teacher is teaching. At the same time, this skill can also help practice sports such as basketball and badminton that require visual tracking.

Visual Tracking Course Concept Elaboration:

Visual tracking ability is the ability of children to follow clues with persistence and anti-interference. The child is usually asked to keep his or her head fixed on a moving object and then check to see if the child can successfully complete the tracking. Visual tracking ability plays a very important role in children's learning, and it is inseparable from children's reading, listening to lectures in class, and writing homework and answering questions.

Children must correctly master the method of scanning words with their eyes in order to improve their reading efficiency and enhance their reading level. For example, children with poor visual tracking ability cannot move their eyes to track a moving object, and it is often difficult to concentrate on the teacher who is constantly moving around in class, which will affect the child's listening effect.

In addition, primary school students need to see, think, and write by hand when writing homework, which requires an organic combination of more complex visual kinesthetics. If the visual coordination and tracking ability is poor, there will be missing words, missing questions, reading mistakes, incorrect written tests, uneven thickness of specific strokes, different sizes of handwriting, and slow speed. In addition, poor visual tracking can also affect his fine motor development.

The method of visual perceptual ability training is as follows:

1.Tangram puzzles.

First, use colored tangram puzzles to spell out a variety of colored graphics (color has a hinting effect); Then use tangram puzzles of the same color to spell out various shapes.

2.Confetti puzzles.

Let your child use colored paper with various colors or patterns to replicate various patterns (e.g. people, plants, animals, etc.), such as piecing together a person with colored paper with various parts of the human body, restoring "dismembered" animals or plants, etc.

3.Build blocks.

Practice building geometric shapes or models with colourful wooden or plastic blocks. Then apply the same color of the shortcut building blocks to build.

4.Guessing. Children are required to solve puzzles, which can be people, animals, shapes, numbers or letters, etc., but the puzzles must be visual information or visual imagination; For example, "a hemp house, a red tent, and a fat white man lives in it" (hit a food, what is it?). ）。

5.A variety of intellectual puzzles.

The original complete color picture is broken into several small parts according to a certain law, and the children are required to restore it according to the original picture.

Three benefits of visual training.

1. It is conducive to enhancing the sense of security and mobilizing the enthusiasm of children to participate in activities.

2. It is conducive to promoting children's ability to live independently.

3. It is conducive to improving children's learning ability.

The eyes are the windows of the soul, and good vision is an important prerequisite for children's intellectual development. We must pay more attention to this aspect of the problem.

The meaning and purpose of visual training are as follows:

Visual training is mainly a very effective means of regulating and alleviating visual fatigue. Visual training is of great help to binocular vision dysfunction, for example, in the clinical common noisy look at the computer or look at the mobile phone for a long time, the eyes are sore, hot or uncomfortable, through visual training, improve our ability to adjust, or after the ability to converge, it will reduce visual fatigue, and some children, through visual training to increase its adjustment power, can control the development of myopia. For example, for civilian personnel who use too much eye at close range, visual training can increase the working time of its entry, and it is not easy to have visual fatigue, visual training is mainly aimed at binocular vision dysfunction, these patients can effectively alleviate visual fatigue, increase the ability to adjust, and alleviate some symptoms of clinical inaccuracies.

Visual training can control the growth rate of myopia, the growth of myopia is affected by many factors, the common factors are the continuous growth of the eye axis, so that the distant parallel rays can not focus on the retina and intersect in front of the retina, forming myopia. In addition, environmental factors are also the cause of myopia. Due to the limited visual range of the child for a long time, the child uses the same adjustment force, resulting in ciliary muscle spasm, inducing visual fatigue, lagging adjustment or advanced adjustment, and accelerating the growth of myopia.

The purpose of visual training is to increase the amplitude of the child's eye accommodation and strengthen its accommodative function, so as to eliminate the impact of accommodative disorders on myopia.

Equipment prepared for visual training

Necessary equipment includes: projectors, computers, blackboards, whiteboards, projection screens and lighting equipment.

Because the main function of the visual training room is to provide users with a full range of visual training services, and these equipment can enable trainers to better introduce and demonstrate various visual training programs to users.

In addition, these devices enhance the effectiveness and experience of training, allowing learners to better engage and improve learning.

In addition, for some high-end visual training rooms, some high-tech equipment, such as 3D glasses, virtual reality glasses, etc., can provide users with a more vivid and rich visual training experience.

Visual skills training is a kind of perceptual learning training, which is mainly based on the five ways of eye movement: fixation, saccade, following, convergence and aggregation, and the training content is divided into the training of basic visual ability and the training of basic visual skills.

Here are some examples of visual skills training:

1. Eye movements, commonly used eye movements include fixation, saccade and follow-up movements. Fixation refers to fixation on a static object for a long time, such as when we recognize a new word. A saccade is when the gaze jumps between different static targets, such as jumping from one word to the next word while we are reading.

Following means that we focus on the goal of continuous motion, for example, when we play ball, we must keep looking at the moving ball in order to make correct judgments and reactions. Defective eye movement function generally leads to the following problems: often forgetting the position, dropping words, stressing, slow reading speed, poor reading comprehension ability, poor motor performance, and difficulty concentrating;

2. Visual focusing, when we look at targets with different distance cavities, in order to ensure that the object is clearly imaged on the retina, we must use our adjustment function, that is, adjust the curvature of the lens according to the distance of the object;

3. Visual discrimination, visual discrimination refers to our ability to accurately distinguish subtle differences.
