See-alpha presbyopia correction machine


1、Use and main features


In order to effectively delay presbyopia, remove eye fine lines and treat eye bags, our company independently developed this presbyopia corrector with independent intellectual property rights.

  • Delay presbyopia by 2 years
  • EMS: remove fine lines and treat eye bags


1.1 Scope of application

Under the age of 45-60 years, the crystal structure was normal, and no cataract surgery was performed. No high myopia or hyperopia, no other eye diseases, intraocular pressure within the normal range. Concentration, strong tolerance, people who can stick to wearing it for two hours.

1.2 Use environment

Use indoors under good lighting conditions; this product is not intended to be worn while exercising.

1.3 Customize the use cycle according to the user’s individual vision condition, and determine the use plan.



  • Product principle and technical parameters

2.1 Product principle

The presbyopia corrector uses a special optical device to force the eye muscles to adjust, reflecting the alpha wave of the ciliary muscle movement, which tends to be synchronized with the gamma wave of the medial rectus muscle movement intensity monitored by the image recognition system, and remains within two hours. This effective synchronized movement of eye muscles can achieve the effect of treating presbyopia.


What are the items to be checked for vision correction in patients with presbyopia?

Eye examination: myopia and presbyopia test.
Slit lamp examination: ocular surface, cornea, pupil, iris, lens, etc.
Lens inspection: Lens accommodation inspection, cataract index.
Fundus examination: Macula, retina, vitreous.
Intraocular pressure examination: high intraocular pressure, low intraocular pressure, glaucoma.
EEG examination.
Same as the camera inspection.



In general, presbyopia patients need to take eye examinations and multiple evaluations to determine whether they are suitable for presbyopia rehabilitation.



Unsuitable population and efficacy analysis


The treatment of presbyopia is currently a problem all over the world. Will the symptoms recur? Is it valid for everyone? In response to these questions, scientists have conducted a large number of experiments, and the efficacy of the following patients is uncertain:

Patients with other eye diseases (such as cataracts, glaucoma, macular disease, amblyopia, strabismus, hyperopia, etc.)
Patients with cerebral nerve damage (such as accidental trauma to the brain, abnormal EEG, etc.)
The eye muscles are not working properly (nystagmus, drooping upper eyelid, incomplete eyelid closure, eye movement disorders, etc.)
Overaged, poor adjustment of the lens, over 65 years old, the effect is not obvious.
Not persistent. The treatment requires persistence for two hours. Some people cannot endure it and give up when they feel not comfortable. Some people will have nausea, dizziness and other adverse reactions, and somnolence account for a part of the percentage.
The effect for women is more obvious than men, and the effect for sporty people is less obvious.



Why does presbyopia treatment take 120 minutes?


The brain’s cognition includes instantaneous memory, short-term memory and long-term memory. The presbyopia rehabilitation system uses optical principles. Only after two hours of intensive training can memory information be formed to achieve the purpose of treatment.


The 120-minute recovery is a one-time uninterrupted treatment, not cumulative. Rehabilitation training must be carried out with both eyes at the same time, not monocular training.



Why can See-Alpha treat presbyopia but not myopia?


If there is no standard, according to the principle of visual information processing, subconscious memory cannot be formed.

Presbyopia can’t see close things clearly and can see far away clearly. When looking at a target with both eyes, the brain knows it is one. When the target is looked closer, it becomes two, but the brain calls out that subconscious memory is one target. After a long period of practice, a clear memory is formed. People with myopia can’t see the distant target. The target has not formed a subconscious in the brain. It can only be seen clearly when you are close. Because of the time difference, there is no subconscious memory, and there is no way to call up the subconscious memory picture, so myopia cannot be treated.




Why set +100, +200, +300 three adjustment points?


There is a close relationship between the angle of the binocular vision and the stretching of the muscles. The break point, blur point and recovery point are different for each person. Everyone’s presbyopia degree is different. The adjustment point is designed to adapt to most patients.
