Description
Technical Field
The utility model relates to a lens check out test set field especially relates to a portable lens harmful light cuts off ability detection device.
Background
The green and red parts of visible light and longer-wavelength electromagnetic waves such as infrared rays, microwaves and radio waves do not harm human bodies, particularly eyes. However, electromagnetic waves having a short wavelength, such as cyan ultraviolet rays in the violet to blue portions of visible light, and X-rays and gamma rays, are harmful to the glasses. The X-ray and the gamma ray do not belong to natural light such as sunlight, generally do not cause harmful influence on human bodies if the X-ray and the gamma ray are not specially close to each other and are watched, and the blue light part in the ultraviolet ray and the visible light belongs to one part of the sunlight, so that the human bodies can not avoid contact in daily life, particularly eyes, and therefore the special blocking lens for blocking the ultraviolet ray and the blue light is beneficial to the eyes. In particular, blue light among the visible light, cyan light having a wavelength of 400 to 500nm, also known as short wavelength, is focused on the tip of the retina because of its short wavelength, and thus it is impossible to accurately recognize an object, and the color is dispersed, so that it is easy to cause eye fatigue. And the shorter the wavelength, the higher the energy, the more strongly stimulating the intraocular optic cells, thus aggravating the eye-stinging sensation and eye fatigue.
In order to block visible light that is harmful to the eye, spectacle lenses (including sunglass lenses) are typically coated with a film that blocks ultraviolet, i.e., UV, light. The coated spectacle lens is detected by a transmittance measuring module, and the measuring module consists of a light source and a sensor for detecting light transmitted through the spectacle lens. The lens to be measured is placed on the measuring module, and after the light is detected, the intensity of the light transmitted through the lens to be measured is detected by the sensor. Since the transmittance of the lens measured by this method is the transmittance of the entire band, a xenon lamp used as a light source and a ULED lamp dedicated to the emission of light having a short wavelength of 400nm or less are used for the measurement. The transmittance of the lens to be measured can be calculated by comparing the intensity of the detected light with the data calibrated in advance. In accordance with the above principle, the ultraviolet measuring device for eyeglass lenses of korean utility model registration No. 20-0204549 discloses a transmittance measuring device, which is embodied by using a lamp capable of generating a fluorescent lamp pattern having a wavelength in the UV-a range in ultraviolet light in a small discharge tube of 4 w as a light source to generate light in a wavelength range required for measurement, transmitting the generated light through a lens to a sensor to constitute an optical system, and labeling the result with a light emitting diode or a number and different colors.
However, the above registered utility model is an apparatus for detecting wavelength range of 320nm to 400nm, and most of the existing spectacle lenses can cut off ultraviolet rays in the above range along with the development of coating technology. In the green light, HEV (high energy viroet) is within the range of 400nm to 420nm, the damage to eyes is larger than that of the wave band above 470nm, and the retina is deformed even if the HEV is exposed to the light for a long time, so that the HEV type light is better cut off. However, while the glasses lens capable of blocking the light of the HEV harmful to the eyes is on the market, no corresponding blocking capability detection device exists in the market, and the consumer cannot visually confirm the blocking capability of the glasses lens.
