Assuming that the focal length of human eye is 22.8mm, the normal distance (comfort distance) of eye cornea front surface to retina is 23
~24mm.When eye-observation object 350mm or more apart from when, human eye works in comfort conditions, and works as eye-observation 150mm
When the object of distance, if people's eye muscle does not adjust, object after eye imaging, image distance from eye cornea front surface away from
From for 26.4mm, if not wearing spectacles, the muscle in human eye portion has to the curvature of the cornea of adjustment eyes and axiallength comes
The focal length and image forming job for changing eyes are away to be clearly imaged, if worked long hours in this state, Jiu Huiyin
Play human eye myopia.
Assuming that the coefficient A=5.0E-4 (1/mm of two polynomial free curved surfaces of Alvarez lens2), the material of lens
For PMMA (refractive index 1.5), clear aperture 20mm, as shown in figure 13, sandwich structure are equivalent to two groups of two panels Alvarez
The structure of lens composition, by formula (2) shown in, when the Alvarez lens of centre move down 2mm, equivalent single group two panels
The focal length of Alvarez lens group are as follows:
The focal length of sandwich structure are as follows: f '=f/2=500 (mm)
Corresponding diopter is+200 degree.
When intermediate Alvarez lens move up 2mm, the focal length of equivalent single group two panels Alvarez lens group are as follows:
The focal length of sandwich structure are as follows: f '=f/2=-500 (mm)
Corresponding diopter is -200 degree.
When putting on the distance of the users of intelligent glasses when observing closer object (such as when reading), on intelligent glasses
It is 200mm that sensor, which detects object with a distance from human eye, and the control circuit on intelligent glasses is according in the driving of this detection range
Between Alvarez eyeglass move down 2.2mm, generate 220 degree of focal power, it is comfortable that the object for making nearby is still imaged on human eye
Distance 24mm position.It avoids human eye because seeing closer object to reach, and makes muscular tone spasm, and cause myopia existing
As.
When intermediate Alvarez lens move down 2.2mm, the focal length of Alvarez lens group are as follows:
Corresponding diopter is 220 degree.
As shown in Figure 12 (a), human eye when observing distant objects, image distant objects on the retina, polished bard
The nerve generation nerve impulse swashed on the retina is transmitted to cerebral cortex generation visual perception along optic nerve fiber.
When seeing object nearby, as shown in Figure 12 (b), if the state holding of human eye sees that the state of distant place is constant, this
When near objects imaging can project the rear portion of human eye retina, in order to see object nearby, the ciliary muscle of human eye clearly
It can tighten, the focal length of human eye is made to shorten, while the extraocular muscle of human eye can make the eyeball of people elongate (i.e. image distance increasing in optical axis direction
Greatly), by the adjusting of the muscle of human eye, object nearby be imaged also can on the retina.If human eye works long hours
Under short distance state, ciliary muscle and extraocular muscle can generate spasm, and it is existing to generate myopia to be restored to the position of relaxation state
As.The intelligent Zoom glasses working principle that we invent is glasses in the object of eye-observation distant place (shown in such as Figure 12 (c))
On range sensor detect the distance of objective plane, the position of mobile activity Alvarez eyeglass makes the light of variable focus lens package
Focal power is 0, and human eye works and (sees the state of distant objects when not wearing glasses, eye muscle, which is in, loosens shape in normal state
State), when eye-observation nearby target (for example reading a book, see the mobile phone screen), the displacement sensor on intelligent glasses detects this
When object distance human eye distance, control activity Alvarez eyeglass is moved to suitable position, makes the light focus of variable focus lens package
Degree is negative (such as -300 degree), and human eye remained to the state when observing distant objects and saw target nearby, and people this when
The muscle of eye is in relaxation state (shown in such as Figure 12 (d)).Intelligent Zoom glasses can make human eye always work in eye flesh
The state that meat loosens especially makes green lack to prevention and avoid eyes from working long hours closely seeing myopia caused by object
The myopia of year student.
