Single Vision 1.56 Ophthalmic Lens Blanks HMC Coated NK55 Japan Monomer

1.56 middle index lenses are one of the most popular lenses all over the world. This determines that Aogang 1.56 single vision lenses have the most outstanding optical features:

 

  • Thickness: Compared with CR39 1.499 lenses, middle index lenses will be thinner under the same prescription,  as the increase in diopters , the difference will be bigger.

 

  • Visual Effect: As high index lenses, like 1.61, 1.67 and 1.74, 1.56 lenses have higher ABBE value, can provide the more comfortable visual experience.

  • Semi Finished Lens:

 

  • The definition of a semi-finished lens

  • The importance of a good semi-finished lens to RX production

 

1. Semi-finished lenses need to have high qualified rate in power accurancy, stability and cosmetics quality.

 

2. High optical features, good tinting effects and hard-coating/AR coating results, realizing the maximum production capacity are also available for a good semi-finished lens.

 

3. Semi finished lenses can reprocessing to RX production, and as semi-finished lenses, not just superficial quality, they are more focus on the internal quality, such as precise and stable parameters, especially for the popular freeform lens.
