Comparison of thickness of 1.60 MR-8 lens and 1.50 CR-39 lenses (-6.00D)
Abbe Number: A number that determinesthe viewing comfort of glasses
| MR-8 | Polycarbonate | Acrylic | CR-39 | Crown glass | |||||||||||
| Refractive index | 1.60 | 1.59 | 1.60 | 1.50 | 1.52 | ||||||||||
| Abbe number | 41 | 28~30 | 32 | 58 | 59 | ||||||||||
·Both high refractive index and high Abbe number provide optical performance similar to glass lenses.
·High Abbe number material such as MR-8 minimizes the prism effect (chromatic aberration) of lenses and provides comfortable use for all wearers.
