Description
Technical Field
The utility model relates to the technical field of spectacle lenses, in particular to a red film myopia spectacle lens.
Background
The spectacle lenses are made of transparent materials with one or more curved surfaces, and are often assembled with spectacle frames to form spectacles after polishing, so that the eyesight of a user is corrected, and a clear visual field is obtained.
In order to improve the transmittance of light after passing through the optical system behind the lens, a film is generally coated on the lens, and a red film is used for changing the phenomenon of yellow visual field in the traditional sense.
The red film is coated with an antireflection film in front of the lens, if the thickness of the film is equal to one quarter of the wavelength of red light (note: here red light) in the antireflection film, then the red light reflected back on both sides of the film will interfere and cancel each other out, and you will not see a little reflection in front of the lens, because the red light has already passed through the lens entirely.
At present, in order to reduce the irritation to eyes in the moment of reflection, eyes with a red film structure are generally adopted, the reflection can be effectively weakened through the film performance of the red film, the eyes are protected, but the anti-reflection effect of a single red film cannot be optimal, so that the lens is required to be further improved to improve the anti-reflection capability.
