A kind of pseudo-myopia correcting spectacle lens
Technical field
The present invention relates to a kind of ophtalmic treatments instrument, more particularly to a kind of pseudo-myopia correcting spectacle lens.
Background technology
According to optical principle, imaging in extraneous object distance and human eye is away from being inversely proportional, the long-term close eye of people, just
This process is voluntarily completed or made up to the synchronization near reflex regulative mechanism that rationality of looking unfamiliar can be mobilized by Diopter accommodation reaction, this
One process is medically known as adjusting reaction.In the adjusting reaction process of this physiological, human eye will reflect in succession
Property ciliary muscle contraction, refractive power enhancing, crystalline lens spheric curvature increase, the optical axis of two eyeballs convergence elongation, pupil contraction etc..
Reaction is adjusted by this series of physiological, clearly image can not only be formed in retina quickly, two can also be imaged onto
On the symmetrical position of eyes retina.Then, by being felt the photosensory cell of activation, pass through neuro-vision access(Depending on road), will
The information of imaging is transmitted to brain occipital lobe cortical visual centers, finally obtains binocular vision, and the object at this time seen just can be very
It is clear.But this complicated physiological reaction is when regulation mechanism encounters the destruction of internal, external various factors, such as a long time
Fatigue eye, cannot when causing the adjusting of ciliary muscle and eye socket periphery orbiculares nervous and spasm, then seeing longer-distance object
Loosen adjusting, the long dioptric system that must change human eye, cause it is ametropia, and according to the destruction of Diopter accommodation reaction system
The difference of situation and degree suffers from heterogeneity, different degrees of pseudo-myopia in succession.
Clinically, eyeball has inherent and external two groups of muscle, and inherent muscle is iris(Sphincter pupillae)And ciliary muscle,
The size of adjustable pupil and lenticular focal length.External muscle has six, can control the rotation of eyeball.
In China, adolescent myopia rate mainly sees TV for a long time about close to 70%, online, plays game etc. and does not pay attention to using eye
Caused by, also there is the fault of reading and writing, books are put excessively close from eye, lighting condition is bad etc., these can all make eyelash
Muscle contracts last in shape body, crystalline lens F degree increase, keep intraciliary muscle in tension, become the crystalline lens of F
It cannot cherish and arrive normal condition again, thus cause pseudo-myopia.
Before this, the common method for rescuing pseudo-myopia mainly has:
1, excimer laser operation for myopia produces cornea flap, then take laser action by cutting cornea
In cornea, reaches and rescue ametropic purpose.Excimer laser is a kind of purple of only 193 nanometers of wavelength invisible to the human eye
Outer Line beam, characteristic are that photon energy is big, and wavelength is extremely short, extremely weak to the penetration power of tissue, will not penetrate intraocular, only be organized
Surface absorption, or damage atomic, excimer laser cornea refractive treatment technology (LASIK technology) lossless to surrounding tissue, is to use
Superficial keratectomy tissue is fabricated to one by a kind of special extremely accurate miniature corneal lamellar diced system (abbreviation keratome)
Cornea flap with the base of a fruit, after overturning cornea flap, under the control of the computer, with excimer laser to the quasi- removal of corneal stroma under valve
Portion of tissue accurately gasify, then resetted in subcornea wash and by cornea flap, in the form of this changes anterior surface of cornea,
Adjust cornea refractive power, enable ambient accurately eyeground be converged to as, achieve the purpose that correction of myopia, it is this to cut
Although the method except part cornea is quick, very risky to eyes there are certain damage.
2, eyeglass is rescued, and Dai Jing is the most common method of children's correction of myopia, and the principle with mirror, which should be taken, can equally make
The eyesight of myopia rescues the most low eyeglass of best vision, but the item needed to pay attention to is more, adheres to that the time is long, especially numerous
It does not notice that in trivial life too much, surely achieves the desired results so differing mostly yet.
Excimer laser operation for myopia and eyeglass rescue although mesh that two methods are attained by correction of myopia at present
, but all there is also certain defects.
Invention content
The shortcomings of the purpose of the present invention is to solve the damage to eyes is big, and treatment time is long, and a kind of vacation proposed
