NAKD IONA Night
Your brain uses light as one of its strongest signals for determining whether it should stay alert or begin preparing for sleep.
For most of human history, that signal was simple:
Light = daytime and alertness
Darkness = evening and sleep
Modern life, however, has changed that pattern. Phones, laptops, televisions, LED lighting and brightly illuminated indoor spaces can expose your eyes to blue-rich artificial light long after sunset.
NAKD IONA Night is designed specifically for this evening environment. Its deep red lenses block more than 99% of blue light, helping create a more natural light environment as your body moves toward bedtime.
Why Night-Time Light Matters
Your body follows a natural 24-hour rhythm known as the circadian rhythm.
As daylight fades, your body normally begins shifting toward its evening state. During this process, melatonin rises as part of the natural signalling involved in preparing for sleep.
However, bright artificial light and blue-light exposure in the evening can interfere with these nighttime cues. As a result, the brain may continue receiving signals associated with daytime alertness even when you feel physically tired.
NAKD Night helps reduce that evening blue-light exposure. Therefore, it can form part of a more intentional wind-down and pre-sleep routine.
The Biology Behind It
Inside your eyes are specialised light-sensitive cells that communicate directly with the brain’s internal circadian clock.
These cells are particularly responsive to shorter-wavelength blue light. During daylight hours, this type of light helps reinforce normal daytime alertness.
At night, however, continued blue-light exposure may delay the body’s normal transition toward sleep. Consequently, reducing evening exposure can help create a more appropriate light environment before bedtime.
By blocking more than 99% of blue light, NAKD IONA Night significantly reduces the amount of stimulating blue light reaching your eyes after dark.
Intentional Blue Light Blocking
Unlike daytime NAKD lenses, which selectively filter certain wavelengths while preserving daytime light cues, the Night lens is designed for much stronger evening filtration.
The deep red tint intentionally alters colour perception. Therefore, these glasses are not intended for daytime productivity or colour-sensitive work.
Instead, NAKD IONA Night is designed for:
- Evening screen use
- Watching television
- Using a phone or tablet after dark
- Laptop use in the evening
- Indoor LED lighting
- Evening relaxation
- Wind-down routines
- Pre-sleep routines
Supports Your Natural Evening Rhythm
By reducing blue-light exposure during the final hours of the day, NAKD IONA Night helps your environment better reflect the natural transition from daylight into darkness.
In addition, it may support:
- The body’s natural evening melatonin rhythm
- A calmer wind-down routine
- A clearer environmental signal that bedtime is approaching
- Easier transition toward sleep
- More consistent evening habits
- Reduced stimulating light exposure before bed
Overall, the goal is simple: reduce unnecessary blue-light exposure when your body should be preparing for rest.
Designed for Sunset to Bedtime
NAKD IONA Night is not intended to be worn throughout the day.
Instead, put the glasses on in the evening, ideally 1–2 hours before bed. This is particularly useful when you are still exposed to screens, television or bright indoor lighting.
Because the lenses provide strong filtration, they create a noticeably red visual environment. Nevertheless, that strong colour shift is intentional and forms part of their night-time function.
Evening Screen Use
Many people spend the final hours of the day using digital devices.
For example, your evening may include:
- Streaming television
- Smartphone use
- Tablets
- Laptops
- Gaming
- E-readers
NAKD IONA Night allows you to continue using these devices while substantially reducing blue-light exposure.
At the same time, lowering overall screen brightness and choosing calmer evening activities can complement your wider wind-down routine.
Deep Red Night Lens
The deep red NAKD Night lens is designed for maximum evening effectiveness.
Because the lens removes a large amount of blue light, colour perception changes significantly. This effect is expected rather than a defect.
For this reason, NAKD Night is built for evening biological light management, not daytime productivity.
Lightweight TR Frame
The IONA frame uses lightweight TR material, making it comfortable for extended evening wear.
The frame offers:
- Lightweight comfort
- Balanced fit
- Flexible construction
- Everyday durability
- Comfortable use throughout your wind-down routine
In addition, the frame incorporates NAKD’s mineral-infused negative ion technology.
UV400 Protection
NAKD IONA Night lenses also provide UV400 protection, helping filter ultraviolet wavelengths up to 400 nm.
Meanwhile, the deep red lens provides the dedicated blue-light blocking required for evening use.
How to Use
Wear NAKD IONA Night in the evening, ideally 1–2 hours before bedtime.
Use them while exposed to:
- Smartphones
- Tablets
- Computers
- Television
- LED lighting
- Bright indoor artificial light
For best use, continue wearing them as part of your evening wind-down routine until bedtime.
Do not wear NAKD Night during the day.
Do not wear while driving.
Because the deep red lenses significantly alter colour perception, they are designed specifically for indoor evening use.
Who Are NAKD IONA Night Glasses For?
NAKD IONA Night may be particularly useful if you:
- Spend evenings on digital screens
- Use your phone or tablet before bed
- Work under bright artificial lighting after sunset
- Want a more circadian-friendly evening routine
- Find it difficult to switch off after a screen-heavy day
- Want to reduce blue-light exposure before sleep
- Are building a consistent bedtime routine
- Prefer an environmental approach to evening light management
