In the digital age, our eyes are constantly exposed to blue light emitted by screens (computers, smartphones, tablets) and sunlight. Prolonged exposure can cause eye strain, irritation, and sleep disruption.

ZEISS BlueGuard lenses offer an effective solution for protecting your eyes, while maintaining an elegant style and optimal visual comfort.

What is blue light?

Blue light is part of the visible light spectrum, ranging from 380 to 500 nm. It is emitted naturally by the sun, but also by digital screens.

Excessive exposure may cause:

  • Eye strain
  • Dryness and irritation of the eyes
  • Disruption of circadian rhythm and sleep

Targeted protection is therefore particularly useful for people who spend a lot of time in front of a screen or exposed to the sun.
