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.
1.56 Mid-Index
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.
Visual Effect: As high index lenses, like 1.59, 1.61, 1.67 and 1.74, 1.56 index lenses have higher ABBE value, that means from the lenses, the wearers can enjoy the more comfortable visual experience.

What Is Blue Light?
For the purposes of this article, we’ll focus on blue light, one of the many hues in all visible light.
Blue light is naturally produced by the sun but also by computer monitors, smartphone screens and other digital devices. In addition to these, blue light is produced by LED and fluorescent lights, and compact fluorescent light bulbs. Blue light is essential in maintaining your sleep and wake cycle, mood and keeping your memory sharp.
Harmful Effects Of The Blue Light

Continuous working on digital screens means focusing and refocusing your eyes back and forth. This leads to eyestrain, dry and sticky eyes.

Blue cut lens effectively blocks 100% UV and 40% of the blue light, reduces the incidence of retinopathy and provides improved visual performance and eye protection, allowing wearers to enjoy the added benefit of clearer and sharper vision, without altering or distorting color perception.
