NAKD IONA Day Pro Yellow
For days when your screen time goes beyond ordinary.
NAKD IONA Day Pro Yellow is the stronger daytime option in the IONA range, engineered for people who spend extended periods in front of computers, laptops, gaming screens and other digital devices.
The deeper yellow lens provides stronger filtration than Day Amber while remaining suitable for daytime use.
It is designed to target the 400–455 nm blue-light range while preserving longer blue wavelengths above 455 nm that remain useful during daytime activity.
How the Day Pro Yellow Lens Works
Blue light covers a broad range of wavelengths.
Rather than blocking the entire blue spectrum, NAKD Day Pro selectively targets the 400–455 nm range.
This allows the lens to provide stronger daytime filtration while preserving longer blue wavelengths above 455 nm.
Because Day Pro uses a deeper yellow lens, you will notice a warmer colour shift when you first put the glasses on.
Most users adapt to the colour change quickly during wear.
Designed for Intensive Screen Exposure
NAKD IONA Day Pro is designed for people whose working day involves significant digital exposure.
It may be particularly useful for:
- Long computer-based workdays
- Multiple-monitor environments
- Gaming
- Coding and technical work
- Remote working
- Extended video calls
- Digital content creation
- Studying
- High-intensity screen environments
- Evening work where daytime-style filtration is still preferred
Day Pro provides stronger filtration than the lighter Day Amber lens.
Supports Screen Comfort
Extended periods in front of screens may contribute to visual fatigue and discomfort.
The Day Pro Yellow lens is designed to soften the visual environment during prolonged screen exposure and support greater comfort during long digital sessions.
It is intended to help reduce:
- Digital eye strain
- Screen-related visual fatigue
- Screen-related headaches
- Discomfort during extended screen use
Supports Sustained Focus
Visual discomfort can make it more difficult to remain focused during long periods of computer work.
By creating a softer screen environment, Day Pro is designed to support sharper, more sustained focus during intensive screen-based activities.
This makes it particularly suitable for long working days, study sessions and gaming.
Stronger Daytime Filtration
Day Pro Yellow provides stronger daytime filtration than Day Amber.
Choose Day Pro if you want:
- Maximum filtration within the NAKD daytime range
- Support during intensive screen exposure
- Stronger filtration for long digital workdays
- A warmer visual environment
- Comfortable prolonged computer use
- Daytime eyewear for gaming or high-screen environments
If natural colour perception is your priority, NAKD IONA Day Amber is available separately.
Lightweight TR90 Frame
The IONA frame is constructed from lightweight TR90, a flexible material commonly used in performance eyewear.
The frame is designed for:
- All-day comfort
- Lightweight wear
- Balanced fit
- Flexibility
- Durability
- Extended screen sessions
Mineral-Infused Frame Technology
The IONA frame incorporates NAKD’s mineral-infused negative ion technology.
This technology forms part of the frame construction and is separate from the optical filtration provided by the lenses.
UV400 Protection
NAKD IONA Day Pro lenses also provide UV400 protection, helping filter ultraviolet wavelengths up to 400 nm.
This complements the daytime blue-light filtration provided by the yellow lenses.
How to Use
Wear NAKD IONA Day Pro Yellow from the time you begin intensive screen use during the day.
Suitable for:
- Desktop computers
- Laptops
- Gaming screens
- Tablets
- Smartphones
- Multiple-monitor workstations
- LED-heavy indoor environments
The deeper yellow lens produces a noticeable warm colour shift when first worn.
This is expected and forms part of the stronger filtration provided by Day Pro. Most users adjust to the colour change within a short period of wear.
Remove before transitioning into your dedicated evening or pre-sleep light-management routine.

Important Information
NAKD IONA Day Pro Yellow glasses are non-prescription wellness eyewear designed for daytime screen and light management.
