Abstract: it reminds us that we can effectively improve the focus by effectively training the ciliary muscle, changing its working state, increasing muscle strength, movement speed and amplitude, so as to make the eyes less tired.
visual training, what you don’t know about visual knowledge
1. Know our eyes
the structure of our eyes is the same as that of the camera. We also have a very fine organ in our eyes – the lens, which is like the focusing device in a camera. It does countless fine focusing movements every day to ensure that we can see objects at different distances at any time.
2. Why are your eyes tired? The
and
lenses are the focusing devices of our eyes, and the muscles drive the lens focusing movement, just like the muscles of our arms and legs. When the muscles work for a long time or are in a working state for a long time, fatigue symptoms will appear.
your eyes will be very tired after long-term close eye use. We call it visual fatigue. It is your eye focusing muscle – ciliary muscle. If it is tired, it can’t produce effective movement, your eyes can’t focus.
III. symptoms of visual fatigue
headache and sleepiness after reading and close work;
and
can’t concentrate, and their work and learning efficiency is low;
and
read slowly and can’t remember what they read;
it is difficult to copy notes from the blackboard;
and
can’t see far clearly after looking close for a long time, and can’t see close again after looking far; After reading
and
, the eyes are tired, sore, sour, dry and uncomfortable, and the vision is double;
when reading, the text moves, beats, swims or floats on the paper;
and
occasionally read “serial”;
myopia increased too fast.
IV. how to alleviate visual fatigue
visual fatigue is caused by ciliary muscle fatigue, which is responsible for the regulation of the eye, or by being in a state for a long time, resulting in the inability of the lens to focus quickly.
because focusing is driven by ciliary muscle movement, muscle strength, speed and amplitude can be exercised. Remind you that you can effectively improve the focus by effectively training the ciliary muscle, changing its working state, increasing muscle strength, movement speed and amplitude, so as to make the eyes less tired.
and
visual training is the most effective way to improve adjustment and reduce visual fatigue.

9. Wear glasses fatigue.
VI. visual training can improve the symptoms of
blurred vision, headache after vision, tired eyes, diplopia, blurred close reading or fatigue;
after long-term close work, or when nervous, they have blurred vision, headache, diplopia and other symptoms.
and
can see the object very slowly, especially when it changes from near to far or from far to near. If you look close and then look at the distance, you need to stay for a while to see clearly. If you look far and then look close, you need to stay for a while to see clearly, resulting in visual discomfort and reduction of effective vision;
headache and tired eyes after reading or doing homework. At the same time, they have blurred vision and don’t want to continue reading.
