“Activated by Transitions” means that these lenses have been carried out by applying photochromism –which is the change in colour according to the quantity of light present– in a new way:
in poor light conditions (for example, when the sky is cloudy), the lenses show a green-yellow hue, which favours contrast definition, highly reduces reflection and empowers the “useful light information” reaching the eyes.
In presence of high sunlight, which goes even through the windscreen, the lenses turn into a copper tone. This colour, which for many drivers is the most comfortable while driving, reduces reflection and brightness, improves the outline definition and the distinctness of red and green road signs.
Finally, when the driver gets out of the vehicle and looks directly at the sun, the lenses darken further until they become dark brown and filtrate the extra-light as to guarantee comfort and visual wellness.
It must be noticed that brown helps to recognize the colours –in particular, green, which is the most recurring colour within the natural environment. These technological innovations must be added to the “consolidated” advantages of Transitions photochromatic lenses, which even in the traditional version block 100% of UVA and UVB rays, protect from reflection and reduce eyestrain.

The “ocular gymnastics” is a daily training comprising useful exercises which can be performed at any moment of the day and anywhere. Like any other muscle, in fact, even the external eye muscles need to be trained in order to maintain tonicity and a few minutes of ocular gymnastics a day may be sufficient to help the eyes to reach a perfect fit.
Like any other part of the body, the eyes, too, need care and attention, especially if we take into account how tiring modern lifestyle can be for the sight. An example for all: the hours spent in front of the computer-screen highly decrease the number of times a person blinks -12 per minute averagely -, “operation” which guarantees hydration, nurture and cleanliness from irritating subjects.
