The ScreenTime clear lens technology provides crystal clear vision with minimal colour distortion. The transparency of the clear lens allows the beneficial blue light through, which is responsible for alertness, motivation, and positive mood, whilst filtering down the damaging blue light wavelengths that cause headaches, migraines, digital eye strain, and even eye damage, such as macular degeneration.
The ScreenTime Lenses filter blue light by 50% across the entire blue light spectrum (400nm-500nm). More specifically, they filter blue light by 50% at 455nm. This is an extremely important feature you should ensure is included in your computer glasses, as the peak wavelength of blue light being emitted by digital devices is 455nm. In other words, for computer glasses to be effective, they need to be filtering this exact wavelength of blue light.
