Darkens during your outdoor activities, reduces the eyestrain due to the digital blue light during your indoor activities.
Ful-Full lenses are not only changing faster than other standard photochromic lenses, but are also changing with glamour colors.
Combining multiple technologies, the Ful-Full lenses are able to provide great protection against blue light rays from digital sources (cell phone and computer screens...), and UV rays from the sun light. They grant a low eyestrain wearing experience.
When our Ful-Full lenses are under UV rays, millions of photochromic cells are activated and change their structure to filter the sunlight. This makes the lenses darkening and "switching to sunglasses mode". Back to a UV rays free zone, their structure change again to disable the filter. The lenses are then in a "blue-light filter mode" only, shielding your eyes from the electronic blue light.
One lens, two modes, a full day protection for your indoor and outdoor activities.
