SleepSpecs

Evening blue light keeps your brain in “day mode,” slashing melatonin. SleepSpec’s FL41 lenses block 98 % of the disruptive 400–500 nm wavelengths, letting your natural sleep hormones flow so you wind down on time.

Key Advantages

• 98 % Blue- & Green-Light Blocking — spectrometer-verified FL41 optics create a gentle “digital sunset.”
• Feather-Lite TR90 Frames — 40 % lighter than acetate, flex without snapping, and stay comfortable through movie-length sessions.
• Noticeable Results — most users fall asleep 15–20 min faster in week 1, sleep more deeply by week 3, and wake clear-headed after a month.

Built for Trust

• Every production batch lab-tested for 98 %+ filtration.
• 1-year warranty against manufacturing defects.
• Endorsed by sleep clinicians and loved by thousands of customers worldwide.

Independent University Findings

Blocking blue- & green-light before bed reliably triggers earlier, deeper sleep.¹-⁶

How SleepSpec Raises the Bar

Trials above used lenses blocking 40–80 % of blue light. SleepSpec blocks a lab-verified 98 % of the same 400–500 nm range, giving you the maximum nocturnal darkness signal—without the colour distortion of 100 % blocking.

Because we exceed the filtration levels shown to work in every study, you can expect results that are at least as strong, drug-free and from night one.^†
