Description
Technical field
The present invention relates to a kind of lifestyle device, and in particular to a kind of anti-blue light eyeglass of colour balance, glasses, equipment and its system
Method is made, the fields such as display, life medical science are can be applied to.
Background technology
Display screen or illuminator in the market is often realized using white light LEDs, because LED light source has low pressure
Power supply, power consumption are less, strong applicability, stability is high, the response time is short, environmentally safe, multicolor luminous etc. advantage.And it is current
Preparing the most frequently used mode of white light LEDs is realized with the mode of gallium-nitride blue LED plus YAG fluorescent powder.Gallium-nitride blue LED
Radiation spectrum intensity focus primarily upon 400-500nm scopes, peak radiant intensity is confined near 415-455nm.It is this white
The radiation spectrum intensity of light LED especially has very strong radiation intensity in blue light in low energy blue wave band.According to Einstein
Theory understands that wavelength is shorter, and energy is then stronger；Thus the greenish-yellow feux rouges of energy ratio of short wavelength's blue light is much better than, therefore it is to people
The injury of eye is also just much bigger.If human eye is had been under the irradiation of high energy blue light, it will visual fatigue, macula retinae become
Venereal disease becomes, even results in the symptoms such as visual impairment.So, the concept of anti-blue light is ready to appear in recent years, the eyeglass of anti-blue light
Largely pour into market.
General anti-blue light eyeglass, is the high energy blue light by removing portion of energy in the blue region of short wavelength, so that
Reduce its injury to human eye.However, because anti-blue light eyeglass filters out part short-wave band, thus through anti-blue light eyeglass institute
The image for being in is often partially yellow, and the transmission visual effect of part anti-blue light glasses then turns yellow significantly, and for image, vision is imitated in itself for this
Fruit has tremendous influence.For example, white pattern transfers anti-blue light eyeglass can then become faint yellow or yellow；Bluish-green colored pattern
Can then become green etc. through anti-blue light eyeglass.Thus current anti-blue light eyeglass or the meeting distortion of glasses color, can not do
To colour balance.
