Structural Optimization: The Engineering of Lenticular High-Power Lenses
Patients with extreme refractive errors—such as myopia exceeding -15.00D or hyperopia over +10.00D—often face the challenge of wearing lenses that are too heavy or too thick for standard frames. Our Lenticular lenses provide a specialized geometric solution by concentrating the corrective power in a central "optical bowl" or aperture. The surrounding carrier area is thinned significantly, acting as a structural support rather than a refractive surface. This approach reduces the overall volume of the lens by up to 60%, drastically decreasing the weight on the wearer's nose and ears. Using high-precision non-spherical curves, we ensure that the transition between the optical zone (typically 30mm to 40mm in diameter) and the carrier zone is as smooth as possible to minimize peripheral visual artifacts. Each lens is calculated based on the specific frame dimensions to ensure the optical zone is perfectly centered over the pupil. By utilizing the world’s highest-index materials, such as 1.74 resin or 1.90 glass, in combination with lenticular geometry, we transform what would otherwise be unwearable "coke-bottle" lenses into functional, lightweight, and aesthetically acceptable optical tools. This technology is vital for aphakic patients and those with high pathological myopia, offering them the ability to choose stylish frames and enjoy all-day comfort without sacrificing the clarity of their prescription.
Specification:
| Aperture Diameter | 30mm, 34mm, 40mm (Customizable) |
| Weight Reduction | Up to 60% vs. Standard Design |
| Max Prescription | Up to -35.00D / +30.00D |
Technological Highlights: Premium Monomers and Coating Integrity
- High-Purity Monomer Selection: We exclusively use high-performance monomers (e.g., MR-series) to achieve superior tensile strength and optical purity, resulting in excellent clarity and minimal risk of yellowing over time.
- Precision Liquid Casting Process: The lenses are produced via a controlled liquid casting method that ensures uniform material density and refractive index consistency across the entire blank, which is critical for accurate therapeutic power zones.
- Advanced Vacuum Multi-Coating (SHMC): Coatings are applied in a high-vacuum chamber, using multiple layers of metallic oxides to create a durable, anti-reflective stack. This process guarantees maximum light transmission and minimal glare.
- Thermal Curing Optimization: A slow and precise thermal curing cycle is employed to maximize the material’s resistance to internal stress, ensuring the finished lens remains stable and optically perfect under varying temperature conditions.
- Integrated Peripheral Defocus Geometry: The therapeutic design is engineered into the mold itself for cast lenses, or applied via digital surfacing for semi-finished blanks, guaranteeing the accuracy and consistency of the myopia control zone geometry.

Frequently Asked Questions (FAQ)
- Q: What is a lenticular lens?
- A: It’s a lens where only the central part has the prescription, to reduce thickness.
- Q: Will people notice the "circle" in my lens?
- A: Yes, a faint transition line is visible, but it is much thinner than a standard lens.
- Q: Does it limit my field of view?
- A: Your central vision is perfect; your side vision is limited to the aperture size.
- Q: Can these lenses be made in 1.74 index?
- A: Yes, combining 1.74 with lenticular design gives the thinnest result possible.
- Q: Are they suitable for children?
- A: Yes, they are often used for children with congenital high prescriptions.
- Q: Can I add a tint to these lenses?
- A: Yes, they can be tinted or made into sunglasses.
- Q: Is the carrier part of the lens clear?
- A: It is transparent, but it does not provide focused vision.
- Q: Do they require special frames?
- A: Small, rounder frames are best for maximizing the lenticular effect.
- Q: How do you measure for these?
- A: Accurate PD and heights are critical to center the optical bowl.
- Q: Why is the price higher than regular lenses?
- A: They are essentially custom-engineered bespoke medical devices.
