Product Introduction
Nano-Barrier Technology: The Science of Super Hydrophobic Surfaces
Maintaining the pristine condition of optical lenses is essential for both visual comfort and the longevity of the product. Our Super Hydrophobic Easy-Clean lenses utilize an advanced fluorocarbon-based nanostructure that is vacuum-deposited as the final functional layer of the lens stack. This ultra-dense molecular barrier significantly reduces the surface energy of the lens, causing water, oils, and other environmental contaminants to bead up rather than spread. With a water contact angle exceeding 110 degrees, droplets maintain a spherical shape and roll off the surface effortlessly, taking dust and debris with them. Beyond its liquid-repellent properties, the super hydrophobic layer provides a smooth, "silk-touch" texture that minimizes the friction caused by cleaning cloths, thereby reducing the likelihood of developing micro-scratches over time. This technology is particularly effective for active users who transition between different temperatures or work in demanding environments where fingerprints, sweat, and facial oils are constant concerns. By ensuring that contaminants cannot bond to the surface, these lenses remain clear for longer periods and require significantly less maintenance than standard anti-reflective lenses. The coating is chemically stable and resistant to thermal expansion, ensuring that the easy-clean functionality remains intact through thousands of cleaning cycles.

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 does "Super Hydrophobic" actually mean?
- A: It means the surface is extremely water-repellent, like a lotus leaf.
- Q: Do these lenses still get foggy?
- A: They can fog, but the fog clears much faster than on standard lenses.
- Q: Does the coating wear off over time?
- A: Our vacuum-bonded layers are highly durable and last for years with normal care.
- Q: How do I tell if my lens has this coating?
- A: Water will bead into perfect droplets and roll off instantly when the lens is tilted.
- Q: Can I use any cloth to clean these lenses?
- A: While any clean microfiber works, the surface is so smooth that cleaning is easier.
- Q: Is this coating available on high-index lenses?
- A: Yes, it is a standard top-layer for our 1.61, 1.67, and 1.74 lenses.
- Q: Does it affect the transparency of the lens?
- A: No, it is a nanometer-thin layer that is 100% transparent.
- Q: Does it protect against salt water?
- A: Yes, it provides a protective barrier against corrosive salt spray in coastal areas.
- Q: Is it safe to use lens spray with this coating?
- A: Yes, but often a dry microfiber cloth is all you will need.
- Q: Why are these lenses better for night driving?
- A: By staying cleaner, they reduce the scattered light caused by smudges and dust.
