Ra Optics Daylight Lenses are made for daytime use. They filter out the harmful blue light from modern light sources, such as LED’s and screen devices, that cause damage to the eyes, and over-stimulate the nervous system, causing increased stress, anxiety, and fatigue. Wear Ra Optics Daylight Lenses any time you have to be indoors in an office, school, or home environment with these light sources. You will notice your eyes and mind naturally relax. Your energy will become more balanced, your mood will lift up, and you will regain a natural flow of energy that allows you to be more productive in whatever you are doing. Daylight Lenses are not necessary in spaces with ample natural lighting, however it is recommended that you open your windows, where possible, to allow in the full spectrum of sunlight. If you cannot open the windows, for example, in an office, it is recommended to use Daylight Lenses, since most modern windows significantly distort the natural spectrum of sunlight for the worse. #raoptics #blueblockers #daylight #naturallight #lighttherapy #screenlenses #consciousliving #biohacking
