Sun, shadow, interior, outside? Photochromic lenses for everything.
Have you never wanted to have smart glasses that adapt to each situation? Well, you're lucky because photochromic lenses do exactly that, and they are the only ones capable of darkening or lightening by themselves according to the amount of natural light there is, so that they guarantee a perfect vision in any situation as well as the protection that we expect with our sunglasses. This, of course, can generate questions like these:
1. How do photochromic lenses work?
2. Who are they indicated for?
3. What are the advantages of photochromic lenses?
Are you interested? Then keep on reading, we reveal everything you need to know before buying a pair of photochromic lenses:
The functioning of photochromic lenses
Basically, when photochromic lenses receive sunlight they darken and when they stop being exposed to it, they become clear. This is due to a chemical reaction suffered by special molecules that cover the lenses and that unfold when receiving UV rays darkening the surface of the lenses and even filtering up to 80% of light.
In the same way, the lenses become clear again when the exposure to natural light decreases, although this process is a little slower (it can take up to ten minutes until the lens regains full transparency).
The duration of this transition depends on the type of lens, the manufacturer and, in addition, is influenced by the temperature (the colder, the faster they darken and the longer they take to clear up).
What users need photochromic glasses
Taking into account the characteristics of these lenses, the first thing that comes to mind are people who have plenty of outdoor activity (cyclists, outdoor workers or active people who simply enjoy going for a walk).
This type of profile is exposed more frequently to sudden changes in luminosity that are attenuated thanks to the adaptability of the photochromic lenses, thus helping to avoid visual fatigue.
However, you do not need to meet any special requirements to be a user of this type of glasses. Anyone who, for example, needs prescription glasses but wants to benefit from the protection offered by sunglasses without having to constantly change their frame, would find the most comfortable option in photochromic lenses.
In addition, if you have a high sensitivity to light, the ability to adapt of photochromic glasses will help you enormously to avoid the visual fatigue caused by the flashes or the frequent and abrupt changes of brightness that we face when we are outdoors.
You should bear in mind that the windshields of cars block ultraviolet radiation to a great extent, which means that your photochromic glasses will not get dark enough to improve your vision while driving, so if you are a driver, it is better to wear normal sunglasses.
Advantages of photochromic lenses
The most obvious advantage is that with photochromic lenses you will have prescription glasses that turn into sunglasses whenever it is necessary, but what does this mean for our vision?
The intelligent adaptation of photochromic lenses is an important rest for our eyes. By not having to make the effort to adapt to changes in luminosity, we avoid glare and visual fatigue and improve the perception of contrasts.
And, if that were not enough, at the same time we are protecting ourselves from harmful UVA and UVB rays in the same way we do when we wear sunglasses.
As you can see, smart glasses exist. Now you decide if they are for you or if you prefer other solutions, such as prescription sunglasses or prescription glasses with solar clips.
