Optical Convergence: The Engineering of High-Definition Digital Bifocals
High-Definition Digital Bifocal lenses represent a sophisticated evolution of the traditional dual-vision lens, merging the reliable structure of bifocals with the extreme precision of modern Freeform digital surfacing technology. Traditionally, bifocal lenses were limited by the constraints of physical molds, which often resulted in optical aberrations near the segment boundary. Our digital series overcomes these limitations by utilizing point-by-point diamond-turning lathes to calculate the optimal curvature across the entire back surface of the lens. This results in a level of sharpness and contrast that was previously unattainable in segment-based optics. By optimizing the transition between the distance carrier and the reading segment, we have significantly reduced the "image jump" effect, providing a much smoother visual transition for the wearer. This design is specifically engineered for presbyopic patients who demand a vast, stable reading field without the peripheral "swim" or distortion often associated with progressive lenses. The digital calculation also allows for an exact match to the wearer's specific pupillary distance and frame wrap angle, ensuring that the optical center is perfectly aligned with the visual axis. Crafted from premium optical monomers, these lenses provide a high-definition experience that enhances text legibility and color perception, making them an elite choice for those who value functional stability and visual clarity in their daily lives.

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.

Penghantaran & Sokongan
- Q: How is a digital bifocal different from a standard one?
- A: It is carved by a computer-controlled laser/lathe, offering much higher precision.
- Q: Is the line still visible on the lens?
- A: Yes, the functional segment line remains to provide the widest possible reading area.
- Q: Does it take long to adapt to these lenses?
- A: Adaptation is nearly instantaneous due to the stable visual fields.
- Q: Can I add a blue-light filter to these?
- A: Yes, blue-light protection can be integrated into the lens monomer.
- Q: Are these lenses thinner than regular bifocals?
- A: Yes, digital surfacing allows for better edge-to-center thickness optimization.
- Q: Are they suitable for driving?
- A: Excellent, as the upper distance zone is entirely free of distortion.
- Q: Can they be made with high-cylinder (astigmatism) values?
- A: Yes, the digital process handles complex astigmatism with extreme accuracy.
- Q: Do they come with anti-reflective coatings?
- A: They are standard with our high-vacuum multi-coating for max transparency.
- Q: What segment widths are available?
- A: Typically 28mm, but custom digital widths can be configured.
- Q: How do I clean them properly?
- A: Use a microfiber cloth and specialized lens cleaner to protect the digital coatings.
