Ray-Ban Light Adaptive Lens: it's nice to be a chameleon
When buying sunglasses, any self-respecting customer must decide on many aspects: model, size, frame material, and, of course, lens color and its properties — dark, classic brown or green-gray, light... In the end, each buyer has to choose one thing, and this can often be difficult.
But what if someone told you: there's no need to choose anymore! After all, there is a lens that combines all the necessary qualities, it can be both protection on a sunny day and a fashionable accessory on a cloudy one.
And such a lens truly exists — it's the Ray-Ban Light Adaptive.
Photochromism: a nearby wonder
The secret of chameleon lenses lies in photochromism — a phenomenon in which a substance changes color under the influence of visible light and ultraviolet rays: light rays cause atomic rearrangements, which can later return to their original structure.
Interestingly, only a limited number of natural and synthetic substances have photochromic properties. In nature, there are only two photochromes: sodalite (changes color from violet to pale green, pale yellow, or colorless) and tugulite (from white to bright pink).
Unlike nature, humanity has learned to produce various photochromic materials: polymer films and liquid solutions containing organic photochromes, as well as silicate and other inorganic glasses.
As for lenses with such properties, they are made from glass, polycarbonate, and other plastics.
Adaptive light
As early as 2008, an application was filed for the registration of the Ray-Ban Light Adaptive trademark, and in 2012 it was officially recognized.
The photochromic effect, which gave rise to this lens, allows it to adapt to changes in light intensity indoors, in the shade, and in the sun.
The Light Adaptive technology involves using a filter for red and orange rays, which reduce visual performance. Additionally, this process is dual: the lens can either darken or lighten depending on the task. The full transition from one state to another takes between 5 to 15 minutes.
It should be noted that frequent drivers may find Light Adaptive less suitable: ultraviolet radiation almost doesn't pass through windshields, so the lens doesn't darken.
In addition to the aforementioned benefits, Light Adaptive lenses block ultraviolet radiation and protect against blue light. This ensures excellent visibility, color rendition, and image sharpness, regardless of the weather conditions.
