What is the difference between the lenses?

Everyday Mode has subtle warmth, the brightest view and the least colour shift. Focus Mode has a pronounced amber tint and visible colour shift. After Hours has a deep red tint, the darkest view and the strongest colour shift. Compare the tested data.

Do ATÉN lenses filter blue light?

Yes. The Lens Guide presents supplier-reported lens-centre transmission, wavelength by wavelength, and the calculated attenuation for each tint. These optical measurements do not establish a health, sleep or performance outcome. View the Lens Guide.
