摘要:
According to the first aspect of the invention, it provides a kind of method of an attribute of the one eye eyeball of device one main body of measurement for being using one: offer bleaching light is provided, invisible background light, to (such as substantially green on its surface, and/or have or one be less than 580 nm wavelength of the sum greater than 400 nm, such as about 514 nm+/the visible bar of bar it is (such as substantially red, and/or have or one be greater than 580 nm wavelength) an and target light? 50 nm), it is applicable to the background light and/or target light (together) of the prevailing stimulation of bar, background light and be stackable according to mutual target light, and target light, it is dignity to main body, so that target light is incident on a parafoveal region of the retina of main body Including method: a) stimulation have using bleaching light low-level bleaching agent main body retina B) after bleaching agent is undertaken, a target light is modulated in an initial luminance, while a background light keeps substantially constant, can not be felt in the modulation of wherein target light by main body C) increase the brightness of brewed target light D) when the modulation of target light by main body be can feel when receive and input from main body, to indicate the relevant threshold value of a bar E) after the input, the brightness of brewed target light is reduced F) this method to determine the component c) repeatedly of the relevant threshold value of a series of bar to e) whithin a period of time.
