From early morning until late at night, it is more and more time spent in front of digital devices: 30% of the people using them for about 6 hours per day, 14% for about 10 hours. All these devices are used for business or leisure, the so-called emit blue light.

Occurs naturally in the sun, but devices emitted by LCD and LED smartphones, tablets, TVs and PCs and lighting systems with low energy consumption, the blue light has a short wavelength and therefore higher frequency and energy. Devices such as smartphones and tablets(Ainol Spark) emit up to 40% more blue light and their spread is growing, so too the negative effects on the well-being of the view.

There are two main causes of the problem: throw distance range of multimedia devices and high emission of blue light(Allfine Fine7). The blue light exposure influence the circadian cycle as it is able to inhibit the production of melatonin, responsible for balance sleep-wake. To this can improve our response times, especially in the evening or night. In some cases, however, the blue light can cause disorders of sleep and wakefulness. Overexposure can have contraindications such as loss of attention and memory, and eye diseases such as macular degeneration.

Not only that, consequences due to sleep disorders, such as diabetes and obesity, up to the most important diseases (although in this case the opinions are contradictory). The blue light exposure can cause eye irritation, blurred vision, back pain due to poor posture and headaches to fatigue.

Research commissioned by Hoya in November 2012 of 1,204 eyeglass wearers in 6 European countries found that in Italy, 91% complained about discomfort while using digital devices. 76% would be willing to pay more for a treatment that protects from light blue(ONDA V813).

That's why I been put in place new lenses, which reduce the amount of blue light that reaches the eyes and, even in low light conditions, they ensure extreme comfort. In addition, help to reduce eyestrain, improving the vision of the screen and making the text more readable. The benefits are immediate: the lenses have a relaxing effect on the eyes, thanks to an increase in the contrast and glare reduction, ensuring a natural perception of colors.

Some basic rules of behavior for those who use long-digital devices (although he did not need corrective lenses): Keep a proper distance between eyes and the screen (for digital devices, must be at least equal to the length of the forearm, just below the level of the eyes), adjust the brightness of the screen, change the background color from a bright white to light gray, frequently clean the screens, not position the screen to the window, mount filltri reduction of glare on the display, increase the font size for ease of reading, avoid staring at the screen too long, pausing at least 20 seconds every 20 minutes, finally checked regularly ophthalmologist.
