The Science
Modern screens and LED lighting produce large spikes of high-energy blue light, particularly in the 400–500nm range.
This light is far more concentrated than the balanced spectrum our eyes evolved under, and prolonged exposure can overstimulate the visual system. During extended screen use, these wavelengths are commonly associated with digital eye strain, visual fatigue, headaches, and reduced viewing comfort.
Balterra’s Daytime (Yellow) Lens is engineered to selectively filter these specific wavelengths, softening the sharp spike of blue light emitted by screens while maintaining natural brightness and colour balance.
By smoothing this harsh light spectrum, the lens helps create a more comfortable visual environment for long hours of screen use.
The result is reduced eye strain, improved visual comfort, and better focus throughout screen-heavy workdays.
