The utility model principle:
The utility model is based on a kind of like this conception: the blurred image on improper eyes retina is not a pure blurred image.A sharp image is also superposeing in blurred image.When the light away from the eyeball optical axis can not focus on the retina and when producing blurred image, still can focus on the retina and produce sharp image near the light of eyeball optical axis.In other words,, exist the nonuniformity of optics in improper crystallization periphery and crystalline central authorities between the two, be equivalent to the spherical aberration of lens.This nonuniformity is the fuzzy root of sensed image.Manage to remove axial ray far away, avoid the crystalline periphery, on improper eyes retina, just only stayed sharp image, reach the purpose that strengthens sensed image.
According to this principle, the utility model is designed a kind of dot matrix sight line diaphragm filter.On opaque sheet material, aperture is set, is worn at the moment.Aperture has replaced the status of pupil, becomes the effective diaphragm of eye optical system.
The paraxial rays that this aperture only permits investing eyes passes through, and blocks axial ray far away, thereby has also just avoided the crystalline periphery, has avoided its inappropriate refraction.At this time, the image on the improper eyes retina should be clearly.Conception has originally obtained realization.
Adopt the utility model sight line diaphragm filter, do not need lens, also do not need eye muscle that the anxiety of crystalline is regulated, easy to use.
The utility model advantage:
1. the utility model sensed image enhancing method and sight line diaphragm filter strengthen visual effect effectively.Can make the people reappear best eyesight when wearing this filtrator, vision is distortion truly and not.
2. the utility model sensed image enhancing method and sight line diaphragm filter make and expand as 0 between the clear visible area of eyes to infinity.This is that any single lens are definitely out of the question.Usually eyes see that the scenery of unlimited distance (beyond 20 meters) is clearly.But, see that instead several centimetres do not known (children's near point is 7-8 centimetre) with interior thing.Wearing this sight line diaphragm filter makes near point near 0 centimetre.So, the nearly eyes of sticker, still can read, show the potential of human eyesight.
3. the utility model sensed image enhancing method and sight line diaphragm filter need not be regulated by tonus of ocular muscles, can not produce fatigue.The utility model is suitable especially to be read, or computer operation, or leisure sightseeing, and normal eye or improper eye all are suitable for.
4. the utility model sensed image enhancing method and sight line diaphragm filter are simple in structure, easy to use, highly versatile.A utensil, applicable anyone, can be used as shared device.The user need not optometry, does not more relate to diagnosis and treatment.
