Mineral Lens Materials

Key features

Mineral lenses are made from high-transparency optical glass. Compared with organic materials, they are more scratch-resistant and offer very high optical quality, but they are heavier and less impact-resistant.

Benefits of Mineral Lens Materials

• High optical quality — Superior transparency and clarity.
• Scratch resistance — Ideal for prolonged use and demanding environments.
• Long-term stability — They retain their optical properties for longer.
• Excellent results with treatments — Particularly effective anti-glare and anti-reflection properties.

Limitations of Mineral Lens Materials

• Greater weight — Less comfortable for larger frames or prolonged use.
• Lower impact resistance — Not recommended for children or sports.
• Less versatile — Not suitable for all modern frames.

Types of Mineral Lens Materials

• Crown glass — Traditional mineral material, excellent optical quality.
• High-refractive-index glass — Thinner and lighter for high power output.
• Photochromic glass — Dynamic sun protection with rapid transition.

When are they recommended?

• The need for maximum sharpness — Precision work, prolonged reading.
• Use in controlled environments — Office, studio, sedentary activities.
• A preference for lenses that are highly scratch-resistant — Heavy daily use.
• High-level powers — High-index versions to reduce thickness.

Relationship with other technical parameters

Mineral Lens Materials can be combined with treatments that improve comfort and visual quality.

• Refractive index — Determines the thickness and weight of the lens.
• Anti-reflective coating — Essential for increasing transparency.
• Photochromic lenses — Dynamic sun protection.
