The higher levels of blue light emitted from digital screens can cause symptoms of digital eye strain such as eye fatigue, headaches, dry eyes and tiredness. Day Swannies® counteract the negative effects caused by blue light by filtering the harshest part of the blue light spectrum.

• Block the most harmful wavelengths of the blue light spectrum found between 400-450nm.
• Protects against symptoms of digital eye strain and computer vision syndrome.
• Allows a natural level of blue light exposure needed for optimal productivity during the day.
• Work longer without tiredness or eye fatigue.
