About Diffraction Glasses
As a piece of high-tech goods, it diffraction glasses are noteworthy for a small, otherwise insignificant film. The layer — it’s called a diffraction grating — is really what the glasses is all about. So what is it about this diffraction grating that’s so amazing?
How do diffraction glasses work?
To begin with, we should get to grips with the nuts and bolts of diffraction. Diffraction is a property of light bending when passing through small apertures or around corners. This principle is used by diffraction gratings to accurately manipulate light. Letting it travel at certain angles and lines.
Second, the diffraction grating in the diffractive glasses is well designed and produced to make the light focus our eyes accurately. Even if there are defects in the lenses (minor scratches, rough surface) of the glasses. Furthermore, the diffractive grating can control light, making light transition smooth and image clear.
Furthermore, diffraction gratings can efficiently suppress light scattering as well as reflection. which is added together to improve image contrast and sharpness. This is one of the main reasons why diffraction glasses have higher quality visual effects than regular glasses.
In other words, the diffraction grating is extremely important as a constituent element of a diffractive glasses. It is realized that a clear image is projected by changing the direction of light. We get more comfortable and natural experiences from seeing things. We hold by the view that with the onward march of technology. Diffractive glasses will gain wider application in the vision corrections of the future.
The role of microstructure
The glasses are sticker-shrined, a decal densely packed with tiny circles. It’s not some average decoration on it – they are tiny little circles but what the circles hold are these fascinating optical structures. Some areas of the lens feature a special effect underneath the sticker. When we look the merchant’s display picture above. We are delighted to learn that image of the original street lamp is still apparent. But it is encircled by an attractive heart-shaped pattern. This is exactly the impossible thing. Which is in such marvelous manner performed by the microstructure in the small circle. In all other common portions of the glasses, light is able to travel through as usual. So that we can clearly see the objects that were there before. In a word, this pair of glasses virtually implements the ‘split pupil’ function – some of the light keeps as it is for imaging. Another part of the fabric cleverly scattered into a beautiful heart pattern.

how should one design the pattern of the phase modulation surface based on the desired heart shape?
This optical ‘trickery’ is made possible by ‘diffractive optical elements’ (DOE) that are embedded in the grey layer of this set of sunglasses. DOEs are a well-known type of optical device in the optics domain. The mysterious world of diffraction To appreciate how these gadgets operate, we need to begin with the key term ‘diffraction’.
In general public perception, ‘light travels in straight lines’ seems to be an unassailable truth, while diffraction is a physical phenomenon that defies this intuition.In some materials, ‘diffraction’ is defined as ‘the physical phenomenon where waves deviate from their original straight path when encountering obstacles.’ This description isn’t wrong, but from a physics perspective, it’s far from capturing the true essence of diffraction. Diffraction is actually a complex form of interference. To truly understand this physical phenomenon, one needs considerable prior knowledge of physics and mathematics. I won’t delve into details here; those interested can look up more information themselves.
While it is far from easy to understand the physical essence of diffraction,many characteristics of diffraction patterns can still be made sense of. For instance, as shown in the figure, when the form of left surface (referred to as diffraction surface in general) is altered, different patterns can be seen on right (called observation surface in usual).
