Red
The hour before bed
Blocks 100% of blue and green light (400 to 570nm), to support your natural sleep cycle before bed.

Yellow
Longer screen sessions, during the day
Blocks 90% of blue light (100% in the 400 to 450nm range), for longer screen sessions and reduced eye strain.

Clear
Work, driving, everyday wear
