"Function Color" increases visibility by cutting the short wavelengths (blue light) that cause glare with the introduction of a special tinting technique. At the same time, by looking through 'Function Color' lenses, a difference in brightness is possible and the contrast has been raised through highlighting the difference in color by the difference in brightness. It has now become possible to see things more clearly.
Shortwave light close to ultra-violet rays (380-500nm) feels like glare, because the energy is strong and because it has a tendency to scatter. "Function Color" increases visibility by cutting the short wavelengths (blue light) that cause glare with the introduction of a special tinting technique.
While reducing glare, the contrast is increased by accentuating the difference in colors. Subsequently objects can be seen more clearly.
These models are recommended in situations where glare and flicker are felt. In particular, when playing golf, it is possible to clearly see the contours of the course and when driving, shadows on the road can be clearly seen. When using a computer, it becomes easy to see text and graphics.
The higher the density of the color of the lens, the more glare will be reduced.
However, the stronger the density, the stronger the emphasis becomes in fashion and so it is also true that there are worries about the lenses matching clothes and makeup. It is because of this that "Function Color" specially uses natural colors in a light density. These are colors that also go well with everyday fashion.
These are only images, so the actual color may vary.
