What is Lens Index?
The lens index refers to the index of refraction (otherwise known as refractive index) of lens material for eyewear. It is a relative measurement number that describes how efficiently the material bends light. Light refraction will depend on how quick light itself passes through the lens.
The difference between 1.56 mid-index and 1.50 standard lenses is thinness. Lenses with this index reduce lens thickness by 15 percent. Full-rim eyewear frames and glasses worn during sports activities are most suitable for this lens index.
The most common materials available for use in lenses used to be glass and a hard resin called CR-39. With the continuous improvement of technology, there are more requirements of CR39(optical/plastic) lenses than glass lenses. We are a manufacturer of optical lens, and in these lenses, 1.56 index lenses are one of the most popular lenses all over the world. Furthermore, lenses with 1.56 index are considered the most cost effective lens on the world market.
1.56 middle index lenses are one of the most popular lenses all over the world. This determines that HONGCHEN 1.56 single vision lenses have the most outstanding optical features:
1. Thickness: In the same diopters, 1.56 lenses will be thinner than CR39 1.499 lenses. As the increase in diopters , the difference will be bigger.
2. Visual Effect: Compared with high index lenses, 1.56 lenses have higher ABBE value, can provide the more comfortable visual experience.
3. Coating: The uncoated lenses are easily subjicted and exposed to scratches, hard coating lenses can effectly scratch resistance.
Anti-reflective coating (also called "AR coating" ) improves vision, reduces eye strain and makes your eyeglasses look more attractive.
These benefits are due to the ability of AR coating to virtually eliminate reflections from the front and back surfaces of your eyeglass lenses.
With reflections gone, more light passes through your lenses to optimize visual acuity with fewer distractions (especially at night), and the lenses look nearly invisible — which enhances your appearance by drawing more attention to your eyes and helping you make better "eye contact" with others.
----Hardness: One of the best quality in hardness and toughness, high impact resistance.
----Transmittance:One of the highest transmittance as compared with other index lenses.
----ABBE: One of the highest ABBE value providing the most comfortable visual experience.
----Consistency: One of the most reliable and consistent lens product physically and optically.
Hard coating: Make the uncoated lenses are easily subjicted and exposed to scratches
AR coating/Hard multi coating: Protect the lens effectively from reflection, enhance functional and charity of your vision
Super hydrophobic coating: Make the lenswaterproof, antistatic, anti slip and oil resistance
