Why Choosing H&C Optik High Index Lenses?
At H&C Optik, we make high-index lenses using Japanese Mitsui Chemical’s advanced MR-7, MR-8 materials and Korean Acrylic Material.
Refractive indices of 1.67 (MR-7) and 1.60 (MR-8) could reduce lens thickness by up to 30% vs. conventional materials, which is ideal for strong prescriptions.

Advantages of H&C Optik MR-7 1.67 High-Index Lenses:
About 30% thinner than standard plastic (CR-39) lenses, good for strong prescriptions
Lower density of MR-7 reduces pressure on nose/ears, good for all-day wearing.
MR-7 High-Index Lenses exceed FDA drop-ball standards and prevent cracking at drill holes.
MR-7 High-Index Lenses have low thermal expansion and resist warping in temperature extremes (e.g., car interiors, winter weather).
Advantages of H&C Optik MR-8 1.60 High-Index Lenses:
MR-8 High-Index Lenses are thinner than CR-39 (1.50) but with better clarity than polycarbonate (Abbe 30)
Lower density of MR-8 reduces pressure on nose/ears, good for all-day wearing.
MR-8 High-Index Lenses have higher impact resistance than FDA standards. Safer for children, sports, and safety glasses.
Ideal for Moderate to High Prescriptions. Perfect for prescriptions between -4.00D to -8.00D (or +3.00D to +6.00D), offering a balance of thinness and optical performance.
