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.

The most common effects of too much blue light exposure are eye strain, blurred vision, and headaches. However, recent studies have focused on blue light’s negative impact on the circadian rhythm and found that watching TV or using a tablet before bedtime, for example, can result in restlessness and disrupted sleep cycles. In extreme cases, too much blue light exposure can even lead to permanent eye damage and vision loss.
Children are especially vulnerable because their eyes have not yet developed natural defenses against UV and HEV blue light. Today, a staggering 97 percent of American kids under the age of four se mobile devices, and teens are spending an average of 6.5 hours per day on screens.
