Native EMF has specifically designed this product to block over 75% of blue and green light while being constructed of acetate so as to avoid any conductivity of radio waves. This item is also anti-glare.
Native EMF only recommends using these glasses at night (after the sun has set) so as to closely replicate a Native EMF environment.
We do not recommend wearing blue-blocking glasses throughout the day as they limit your eyes to exposure to natural UV light. In the evening we only recommend using glasses that filter 75% blue light as the modern environment has an exaggerated amount of blue light.
