If we can handle laser-level blue light, everyday screens are easy. Your screen stays clear and true to color—while your eyes stay comfortable. Blue-light protection, re-engineered for the way we live and work today. This is Simmpo.
Most blue-light products stop at passing a test. Simmpo builds far beyond the minimum—engineered for the wavelengths that matter most to your eyes.Simmpo pushes blue-light protection to its limits—not only filtering 90% of harmful 435–440 nm blue light, but also over 95% of high-energy 400–420 nm wavelengths. By targeting both ranges, we cut overall blue-light toxicity by about 50%—and still keep your screen clear, accurate, and highly transparent.
Most blue-light products use simple dyes just to pass a test. Simmpo goes far beyond—using nano-photonic absorption and long-term stability engineering to target the most damaging wavelengths and keep that performance for years.
Reaching 90% absorption in the deepest blue wavelengths requires extreme control— nano-scale particle sizing, ultra-tight spectral alignment, and coating accuracy within just a few percent. And despite this level of precision, your screen stays clear and true to color. This is NPA Tech—blue-light filtering pushed to the edge of what’s possible.
High-absorption particles are powerful—but naturally unstable. EndureX solves this with a photon-shield encapsulation layer that protects each nano-particle from heat, moisture, UV exposure, and rapid temperature swings. The result? Blue-light performance that doesn’t fade, weaken, or turn yellow over time.
When it comes to eye comfort and safety, not all certifications are equal. TÜV Rheinland sets one of the toughest blue-light standards in the world— and it doesn’t just ask “how much is blocked?”, it also checks that your screen still looks and feels like a screen you actually want to use. While most blue-light claims never face serious testing, TÜV’s BLR (Blue Light Reduction) system measures:
There are seven BLR levels in total, and BLR 90 sits at the very top — reserved only for products that pass the strictest thresholds.
BLR performance at a glance
TÜV Rheinland blue-light reduction grades vs. Simmpo's certified result.
| LEVEL | 435-440 NM REDCUTION | OVERALL HARMFUL BLUE REDUCTION | COLOR SHIFT (ΔCCT) | TRANSMISSION |
|---|---|---|---|---|
| 70% BLR | ≥ 70% | ≥ 30% | ≤ 500 K | ≥ 80% |
| 80% BLR | ≥ 80% | ≥ 40% | ≤ 500 K | ≥ 70% |
| 90% BLR (TÜV spec) | ≥ 90% | ≥ 50% | ≤ 500 K | ≥ 70% |
| Simmpo (BLR 90 certified) | 90.89% | 55.5% | ≈ 462 K | 70.1% |
Most blue-light filters push your display down toward a warm 4000K tint—whites turn yellow, and skies lose their crisp blue. Simmpo’s optics keep your screen close to its native 6500K standard, measured at 6038K with only a subtle 462K shift. Photos, videos, and icons still look natural and accurate—you get eye comfort without the “golden filter” look.
HIGH-TRANSPARENCY CLARITY
Even with advanced blue-light reduction, Simmpo maintains high light transmittance around 70%. Your screen stays sharp and detailed—no haze, no milky washout—so movies, games, and fine text all remain clear and immersive. You protect your eyes without feeling like there’s a filter in the way.
Simmpo doesn’t just protect your eyes—it shields your phone too, with a seven-layer ImpaX cushioning system that absorbs impact and boosts drop resistance by up to 5× compared to standard screen protectors.
Choose Zero Compromise. Choose Simmpo
Other screen protectors make you choose between color accuracy and eye comfort. Simmpo is engineered differently: get perfect, true-to-life colors and superior, military-grade protection—all in one.

Sarah M｜San Diego, CA★★★★★ | My eyes finally feel relaxed.
I work in digital marketing and spend 10+ hours a day in front of screens. After switching to the Simmpo S-90, I noticed the change right away — no more burning or dry eyes at night. The blue light filter actually works, and colors still look perfectly natural. Finally, a screen protector that protects my eyes as much as my phone.
James R｜Austin, TX★★★★★ | Dropped my iPhone — zero damage!
I’m clumsy and drop my phone all the time, but this protector didn’t even flinch. The ImpaX™ cushion layer absorbed the hit like magic. My iPhone landed face-down on concrete and survived without a scratch. This thing is built like a tank — seriously the best screen protector I’ve ever owned.
Emily L｜Boston, MA★★★★★ | Game-changer for long hours.
As a college student, I’m constantly on my phone and laptop. The S-90 makes my screen easier on the eyes without dulling the brightness or colors. It’s smooth, anti-glare, and doesn’t smudge. I used to feel eye strain after a few hours — now I can study or game late without discomfort.
Rachel K｜Seattle, WA★★★★★ | Perfect for parents and kids.
I got the Simmpo S-90 for my girl’s iPhone because she’s always watching videos. Her eyes don’t get tired anymore, and I can tell the blue-light filter really helps. The best part? It’s super durable. she’s dropped his phone twice already — not a single crack. I’m buying one for my phone too!
David Ha｜New York, NY★★★★★ | Professional quality for designers.
I’m a product designer and extremely picky about color accuracy. Most blue-light protectors mess up the display, but Simmpo’s NPA Tech keeps everything true-to-life. The screen still looks stunning while reducing harsh blue tones. Plus, the impact resistance is no joke — my phone’s taken hits and still looks new.
