FAQ
Questions
Answers are draft copy for review.
When should I wear Circadia?
–
After work, ideally before sunset, when you’re still using screens, TV or bright indoor lighting. Many people put them on one to two hours before bed. Switch to Solace for the last hour if you want the deepest filter.
Can I drive with these lenses?
–
Halo, Lumen and Shift are suitable for day and night driving. Circadia is for day driving and the drive home only. Solace is not for driving.
Will these help me sleep?
–
They’re designed to help promote better sleep quality. In the evening, our warmer lenses cut the blue light from screens and indoor lighting, helping your body prepare for sleep. Wear Circadia after work and switch to Solace for the last hour before bed.
What does “supplier-tested” mean?
–
Blocking figures come from our lens supplier’s in-house reports for 380–500nm light. They have not yet been independently verified.
Can I get prescription lenses?
–
Yes. Send us your script and we’ll evaluate it, including whether it suits the Caelum frame, then come back with confirmed feedback and a quote. Pricing is quoted after evaluation. See how prescription works.
How do delivery and returns work?
–
Courier delivery anywhere in South Africa: R99, or free on orders of R1,399 or more (after bundle pricing).
