近視制御レンズ
Clinically designed to slow myopic progression while preserving central vision clarity.
Myopia is rising rapidly and could affect over half of the global population by 2050. Casiolens YOULI lenses aim to slow this trend by targeting the optical causes of eye elongation — not just the symptoms.
Peripheral hyperopic defocus is a known signal for axial eye growth. YOULI lenses redirect this signal by introducing myopic defocus zones across the lens surface to inhibit elongation.
At the heart of YOULI is a grid of 1,339 microlenses that subtly alter peripheral light rays while preserving sharp central vision — delivering both correction and control.
All lenses use durable, high-index polycarbonate and integrate UV and blue light filters directly into the material.
| Parameter | Specification |
|---|---|
| Material | Polycarbonate (1.591), optional 1.60 |
| Microlens Count | 1,339 |
| Defocus Power | +3.5D to +4.5D |
| Prescription Range | SPH 0.00 to -6.00D / CYL 0.00 to -2.00D |
| UV / Blue Filter | Built-in protection |
| Abbe Value | 30.6–31 |
| Optional Coatings | Anti-reflective, hydrophobic, anti-smudge |
Ideal for children aged 6–16 with progressive myopia. Multiple studies show 30–60% reduction in axial growth vs single-vision lenses. Compatible with most pediatric frames.
スーパークリアレンズ
Engineered for the highest light transmission and razor-sharp clarity in every condition.
Super Clear Lenses use premium optical resins with AR coatings that reduce reflections to below 1%. The result: pure, undistorted vision with minimal glare — even under harsh lighting or during night driving.
| Feature | Value |
|---|---|
| Refractive Index | 1.56 / 1.60 / 1.67 |
| Abbe Value | 40–42 |
| Coating | Hi-Vision AR + Hydrophobic |
| UV Protection | UV400 (100% UVA/UVB) |
ブルーコントロールレンズ
Digital eye strain and blue light exposure are rising concerns. Our ultra-clear, high-index lenses deliver superior protection — without yellow tint or visual compromise.
| Index | Abbe Value | Design | Coating | Best For |
|---|---|---|---|---|
| 1.56 | 40 | Aspheric | Green/Blue/Purple | Low (-0.50 to -2.50) |
| 1.60 | 41 | Aspheric | Green/Blue/Purple | Moderate (-2.50 to -4.00) |
| 1.67 | 32 | Aspheric | Green/Blue/Purple | High (-4.00 to -6.00) |
| 1.74 | 32 | Aspheric | Custom | Very High (> -6.00) |
Why Abbe Value Matters: Higher values reduce chromatic aberration for sharper vision.
| Feature | Traditional Blue-Cut | Next-Gen Lenses |
|---|---|---|
| Base Color | Yellowish Tint | Crystal Clear |
| Blue Light Blocking | 30–40% | 40–50% (UV420) |
| Reflections | 2–3% | <1.5% |
| Prescription Range | Limited | 1.56–1.74 options |
Pro Tip: Accurate PD measurement is essential above -5.00 prescriptions.
