If you are trying to decide between our Night amber lens and our Night+ red lens, the honest answer depends on one thing: what your evenings actually look like, not which lens sounds more serious.
What Each Lens Is Built For
Our Night amber lens filters up to 95% of blue light. It is designed to be worn from sundown onwards, through the hours of general evening activity: dinner, reading, low-intensity screen use, unwinding before the final stretch toward bed.
Our Night+ red lens blocks 99.9% of blue light and filters over 97% of melatonin-suppressing green wavelengths up to 600nm, independent spectrometer verified. It is built for the one to two hours directly before sleep, when the light you are exposed to has the strongest influence on how quickly melatonin rises.
Choose Night, Amber, If
- You want a lens to wear for several hours in the evening, not just the final stretch before bed
- You are new to circadian eyewear and want a lighter introduction
- Your screen and lighting environment in the early evening is moderate, not intense
Choose Night+, Red, If
- You are using screens or under bright artificial light in the one to two hours before bed
- You already struggle to fall asleep or wind down once you are in bed
- You want the most complete filtering available in the final window before sleep
Can You Use Both
Yes, and many people do. Our Night amber lens through the early evening, switching to Night+ in the final one to two hours before bed, gives you graduated protection that matches how melatonin actually builds across the evening rather than switching on all at once.
The Expansion Beyond Sleep
Whichever lens fits your routine, the goal is the same: giving your circadian system a clear signal in the hours it needs one. That signal supports more than sleep onset. It supports the hormone cascade, energy, and mood that follow from consistent sleep timing.

Frequently Asked Questions
Is Night+ just a stronger version of Night?
Yes, in terms of blocking percentage, but the intended use differs. Night is built for general evening wear. Night+ is built specifically for the one to two hours before bed.
Which lens should a first-time buyer choose?
If you are new to circadian eyewear, our Night amber lens is a lighter starting point. If you already have consistent trouble winding down, start with Night+.
Can I wear Night+ all evening instead of Night?
You can, though the tint is more intense. Many people prefer amber for general evening wear and reserve Night+ for the final stretch before bed.
Do both lenses come in the same frames?
Yes. Every Balterra frame is available in both Night and Night+, so you can choose based on fit first and lens second.
