    Core tip: a common problem of sunglasses is the occurrence of back glare

    Back glare is generated when light hits the back of the lens and then reflects into your eyes

    The function of anti reflective protective coating is to reduce the reflection of the lens to light

    The antireflection coating is basically like this: the lens surface and coating cover a quarter wavelength of an exact thickness that needs to be eliminated with a specific refractive index

    Most of the generated light passes through the lens, but some of it is reflected out, part of the lower surface coating of the glass coating of the lower part

    In other words, the reflected light consists of two parallel waves and a determined phase difference

    When these parallel waves are accurate Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint

    In fact, there is no ugly color in the wall paint, only the disharmonious color matching

    The use of wall color contains the knowledge of health

    Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health

    Grasp the basic principles of wall color and paint a colorful space

    1、 Wall paint color selection notice 1

    Light color is generally used for the top surface

    Light colors make people feel light, dark colors make people feel heavy

    Usually, the treatment of rooms is from top to bottom, from shallow to deep

    For example, the ceiling and walls of rooms are white and Paint Home News: a common problem of sunglasses is the glare after it appears

    The glare back is generated when the light hits the back of the lens and then reflects into your eyes

    The function of anti reflective protective coating is to reduce the reflection of the lens to light

    The antireflection coating is basically like this: the lens surface and coating cover a quarter wavelength of an exact thickness that needs to be eliminated with a specific refractive index

    Most of the generated light passes through the lens, but some of it is reflected out, part of the lower surface coating of the glass coating of the lower part

    In other words, the reflected light consists of two parallel waves and a determined phase difference

    When these parallel waves are accurate, the light goes out due to interference and whether there is reflection

    As with the anti scratch protective layer, the anti reflection coating is a very solid and thin film on the lens

    The refractive index of antireflection coating material is between air and glass

    This makes the intensity of reflected light on the inner and outer surfaces of the film almost equal

    When the thickness of the film is about a quarter of the wavelength of the light wave, the light reflected from the inner and outer surfaces of the film will cancel each other by eliminating interference, so as to minimize the glare you see

    Antireflection coating is also applied to the front surface of refractive contact lenses and some sunglasses to eliminate the "hot spots" caused by the strong light reflected by the lenses
