Introduction to Five Types of Multi-Point Defocus Lenses: Safeguarding Visual Health

In nowadays, adolescent vision issues have attracted increasing attention. Multi-point defocus lenses, with their unique design, play a crucial role in slowing down axial elongation and protecting eyesight. Below is an introduction to five high-performance multi-point defocus lenses from Ideal Optical—each tailored to solve specific visual pain points of adolescents, catering to diverse needs.

1. PC Annular Multi-Point Defocus Lens: Lightweight & Impact-Resistant for Active Teens
Aiming at the pain points of adolescents who love sports (easy lens breakage) and have long wearing time (nasal bridge pressure), this lens integrates practicality and protection:
Design & Function: Adopts peripheral high-order astigmatic aberration rings to effectively enhance defocus signals, paired with a youth vision optimization design that slows down the rate of axial elongation, guarding the visual development of adolescents.
Material Advantage: Uses HPC high-performance material—lightweight to reduce nasal bridge pressure, and with excellent impact resistance, avoiding lens breakage caused by accidental falls during sports.
Visual Adaptation: The multi-micro-lens design fits the visual habits of adolescents, creating a stable and safe viewing environment, which is not easy to cause visual fatigue even after long-term wearing.

2. PC Polygonal Multi-Point Defocus Lens: Internationally Certified for Stable Vision Control
For parents worried about "unreliable vision control effects" and "short lens service life", this lens relies on core technology and high-quality materials to solve concerns:
Core Technology: Features a dot-matrix diffusion design that delays axial elongation and controls vision loss; adopts internationally renowned defocus technology, with a proven effect on inhibiting eye growth through clinical verification.
Coating & Clarity: Uses German precision optical coating—ensures high light transmittance for clear imaging, and has strong wear resistance, maintaining good optical performance even after long-term use (such as frequent wiping).
Material Safety: Made of Japanese-imported PC material, with ultra-high toughness and good flexibility, which is not easy to crack or deform, suitable for adolescents with active lifestyles.

3. 1.60 MR Tough 8th Gen - Annular Multi-Point Defocus Lens: Standard-Compliant for Comprehensive Protection
Targeting the needs of adolescents with medium to high myopia (concerned about lens thickness, imaging clarity, and compliance), this lens combines high density, high standards, and high durability:
Defocus Density: Equipped with 1,092 micro-lenses to achieve multi-point micro-defocus, with higher defocus density that intervenes in vision more comprehensively, reducing the risk of myopia progression.
Optical Performance: Has an ultra-high Abbe number of 40.8 (higher Abbe number means less chromatic aberration), enabling clearer imaging and effectively reducing visual fatigue caused by long-term reading or screen use.
Practical Advantages: Integrates impact resistance and wear resistance—thinner than standard lenses of the same power, lighter to wear, and not easy to break, suitable for daily use and outdoor activities.

4. 1.56 Polygonal Multi-Point Defocus Lens: Blue Light Blocking for Screen-Friendly Teens
For adolescents who use electronic products (mobile phones, tablets, computers) for a long time (at risk of blue light damage and overcorrection), this lens provides targeted protection:
Defocus Design: Composed of 666 micro-lenses for multi-point micro-defocus, providing all-round care for eye health and inhibiting myopia progression from multiple angles.
Clear Imaging: Has an 11mm diameter (Φ11mm) central correction zone—enhances the retinal focus depth, making object viewing clearer and more stable, avoiding blurriness when switching between near and far vision.
Blue Light Protection: Equipped with a blue-light blocking hardened coating—blocks harmful short-wavelength blue light (400-450nm) emitted by screens, and has no yellow tint, ensuring no distortion of color perception (e.g., no yellowing when viewing white screens).
Correction Safety: The defocus power range of +4.0D to +6.5D increases disparity, effectively preventing overcorrection (avoiding "myopia deepening due to excessive correction").

5. 1.56 Full-Focus Lens: Smooth Vision Transition for Daily & Sports Scenes
Aiming at the pain points of "obvious visual discontinuity" and "narrow field of view" of traditional defocus lenses, this lens focuses on improving wearing comfort:
Full-Field Design: The focal points on the lens are continuously distributed, allowing wearers to have a smooth transition when viewing objects (e.g., from blackboard to textbook, from far to near), with no obvious "jump" in vision.
Vision Control: The dynamic defocus intervention function adjusts the peripheral power to simulate the natural refraction state of the human eye, slowing down axial elongation while ensuring comfortable vision.
Wide Field of View: Applies free-form surface technology—the lens curvature follows eye movement, expanding the effective viewing area. Whether in class, reading, or playing basketball, running, wearers can enjoy a wide and natural field of view without "blind spots" at the edge of the lens.

In the journey of safeguarding adolescent visual health, the right choice of lenses plays a pivotal role. The five types of high-performance multi-point defocus lenses introduced above, with their unique technological advantages and targeted designs, cater to the diverse needs of different adolescent groups—whether it’s lightweight durability, precise defocus control, blue light protection, or natural visual experience. As a professional optical brand dedicated to visual health, Ideal Optical has always adhered to the concept of integrating cutting-edge technology with user demand. Each of these multi-point defocus lenses is crafted with strict quality control and in-depth research on adolescent visual development, aiming to provide reliable, comfortable, and personalized eye protection solutions. If you are looking for suitable vision correction and protection products for teenagers, Ideal Optical’s multi-point defocus lens series is definitely a trustworthy choice, accompanying young people through a healthy visual growth journey.
