Materials 1.67(MR-7)

Ultra-Thin& Lightweight: Provides lenses up to %45 thinner and lighter than standard CR-39, making it ideal for high prescriptions.

Premium Optical Quality: With an Abbe value of 32, MR-7 maintains acceptable optical clarity whilereducing chromatic aberrations compared to other super high-index materials.

Superior Mechanical Strength: High resistance to stress, cracking and deformation – making it a safe choice for modern frames.

Full UV Protection: Integrated UV400 filter, blocking harmful UVA and UVB rays up to 400 nm.

Excellent Coating Compatibility: Perfectly suited for advanced coatings such as SHMC, Blue, Sun, Mirror, and photochromic treatments.

Rimless Frame Friendly: Designed to withstand drilling and mounting in rimless and semi-rimless frames.
