China Optical Lens Blanks Semi Finished Factories – Highly Recommend 1.60 MR-8 Semi Finished Ophthalmic Lenses Blanks – YOLI Detail:
What Semi Finished Lens Blanks Can do?
Spectacle lenses production units that transform semi-finished lenses into finished lenses according the precise characteristics of a prescription.
The customization work of laboratories enables us to provide a wide variation of optical combinations for wearer needs, especially as regards the correction of presbyopia. Laboratories are responsible for surfacing (grinding and polishing) and coating (coloring, anti-scratch, anti-reflective, anti-smudge etc.) the lenses.
Why Highly Recommend MR-8?
Refractive Index 1.60
The best balanced high index lens material with the largest share of refractive index 1.60 lens material
market. MR-8 is suited to any strength ophthalmic lens and is a new standard in ophthalmic lens material.
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.
Strain Free
MR-8 resin is uniformly polymerized in a glass mold. Compared to injection molded polycarbonate lenses,
MR-8 resin lenses show minimal stress strain and offer stress free clear vision.
