Mineral Lenses: A Technology of Optical Excellence at Visionet
At Visionet, we are the only online opticians offering mineral corrective lenses, a premium solution for those seeking uncompromising visual quality. We are committed to providing precision products, combining advanced technology and optical expertise.
Mineral lenses offer an alternative to the commonly used organic lenses. They stand out for their exceptional optical quality and durability. Available in single vision (for simple or reading vision) and HD Free-Form progressives for clear vision at all distances, these lenses can be mounted on all compatible rimmed frames with lenses not exceeding 56 mm in width.
Our HD Free-Form progressive lenses are at the forefront of innovation, offering wide vision and smooth transitions with optimized visual zones thanks to next-generation design. This technological precision reduces peripheral distortions, ensuring more natural vision.
The Characteristics of Mineral Lenses: Benefits and Constraints
Advantages of Mineral Lenses
Mineral glass is renowned for its superior optical properties compared to organic lenses. Mineral lenses are made from silica materials, offering better light transmission and more precise correction of visual defects.
- Excellent optical quality: Thanks to better light refraction, mineral lenses offer superior visual clarity, ideal for wearers seeking distortion-free vision.
- Scratch resistance: Unlike organic lenses, which are more prone to scratches, mineral lenses are much more resistant to micro-scratches. This makes them a durable option for long-term use.
- Optical stability: Mineral lenses maintain their shape and optical characteristics over time, as they are not sensitive to temperature changes.
- Aesthetic: Due to their denser composition, mineral lenses can be thinner, even for high prescriptions.
Constraints of Mineral Lenses
Despite their performance, mineral lenses have some drawbacks:
- Weight: Mineral lenses are heavier than organic lenses, which can affect comfort during prolonged wear.
- Fragility: Despite their scratch resistance, mineral lenses are more fragile in case of impact and can break more easily.
- Limited compatibility: They can only be mounted on rimmed frames, as rimless or semi-rimmed frames cannot support this type of glass.
HD Free-Form Progressive Lenses: Wide and Precise Vision
The HD Free-Form progressive lenses available at Visionet are designed to offer clear vision at all distances. Free-Form technology allows each lens to be customized to the user's visual needs, reducing distortions and providing a wider field of vision.
Mineral Sunglass Lenses: Protection and Optical Quality
In addition to visual correction, mineral lenses can also be used as sunglass lenses, offering UV protection while guaranteeing remarkable optical quality. At Visionet, we can replace the lenses of nearly 70% of sunglasses with mineral sunglass lenses, with or without correction.
Mineral sunglass lenses are available in three shades: brown, gray, and green G15. Each shade has its benefits: the brown tint enhances contrast, the gray maintains a natural color perception, and the green G15 provides a good balance between glare reduction and color perception.
