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.
最も深いブルー波長で 90% の吸収率を実現するには、極限レベルの精密制御が求められます。ナノスケールでの粒子サイズ設計、超高精度のスペクトル制御、そして数%以内に抑えられたコーティング精度。こうしたナノレベルのエンジニアリングによって、目にとって最も影響の大きい波長を的確に吸収します。それでいて、画面のクリアさと自然な色再現はそのまま。これが NPA Tech。ブルーライトフィルタリングを、可能な限界まで押し上げたテクノロジーです。

高吸収ナノ粒子は非常に強力ですが、本来は不安定になりやすい特性があります。EndureX は、Photon-Shield レイヤーによるカプセル化構造によってこの課題を解決しました。各ナノ粒子を熱・湿気・紫外線、そして急激な温度変化から保護します。その結果、ブルーライト性能は時間が経っても低下せず、劣化せず、黄ばむこともありません。

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.
