Vision care device

Abstract

The invention provides a vision care device, comprising a light source apparatus and a control unit in connection with the light source apparatus. Under the control of the control unit, the light source apparatus flashes at a natural vibration frequency of a crystalline lens. Through the effect of the flashing light source, the crystalline lens generates resonance so as to realize effective training, so that the refraction ability is restored or improved and the aging speed is reduced. In this way, good adjusting amplitude is achieved under the effect of ciliary muscles, thereby fundamentally solving the problem in vision correction. The invention also provides a method for measuring the natural vibration frequency of the crystalline lens. The measurement is carried out by a frequency measuring unit formed by the flashing light source and a vibration sensor for measuring the vibration frequency and the amplitude of the crystalline lens. The method causes the crystalline lens to vibrate by providing the flashing light source, and obtains the flashing frequency of the light source during the resonance of the crystalline lens, whereby the natural vibration frequency of the crystalline lens is determined. The method is simple and reliable and is easy to realize.

Description

technical field

[0001] The invention relates to a health care device, in particular to a vision care device for maintaining and restoring eye adjustment range. Background technique

[0002] Long-term myopia causes the lens to lose its elasticity and the ciliary muscle to lose its vitality, thereby reducing the adjustment power and forming myopia.

[0003] The main methods of traditional vision correction are additive method and refractive corneal surgery. Both of these methods are not aimed at the correction of the regulatory system, so they are methods that treat the symptoms rather than the root cause.

[0004] There are also mechanical massage methods such as vision exercises and massagers for vision maintenance or vision correction, which are only helpful to the ciliary muscle and can achieve certain results, but often require widening or squinting of the eyes when looking at things In order to obtain sufficient adjustment effect, if things go on like this, it will cau...

Examples

Embodiment Construction

[0044] At first the principle of the present invention is described as follows:

[0045] After passing through a lens, parallel rays focus to a point, and the distance from the point to the center of the lens is the focal length.

[0046] Diopter or focal power, expressed in English as "Dioptre", is a unit for measuring the refractive power of a lens. The length of the focal length f indicates the size of the refractive power. The shorter the focal length, the greater the refractive power. The reciprocal of the focal length is called the focal power of the lens, or diopter, with means, that is: φ = 1 f

[0047] Convex lenses (such as: long-sighted lenses) are positive (+), concave lenses (such as: near-sighted lenses) are negative (-).

[0048] The unit abbreviation of diopter is D, and the unit of International System of Units is m-1.

[0049] Generally, glasses often use degrees to express diopter, and th...
