Refractive Index
Lens materials are classified on their refractive index. This refractive index is the ratio of the speed of light when it travels through air to the speed of light when it passes through the lens material. It is an indication of how much light is bent as it travels through the lens. Light is refracted, or bent, at the front surface of the lens, then again as it exits the lens.A denser material bends light more, so not as much material is needed to achieve the same refractive effect as a less dense material. Hence the lens can be made thinner, and also lighter.

1.61 High Index

For those looking for a more modern look, 1.61 high-index lenses may just fit the bill. These ultra-thin lenses are suitable for relatively thin eyewear frames or prescriptions that have an SPH correction between +/- 4.25 and +/- 6.75, and a CYL correction between +/- 2.25 and +/- 3.00.

What are the Benefits of High Index Lenses?

With regular eyeglasses lenses, the center of the glasses is thinner and the outer edges are thicker to facilitate refraction which is what makes prescription glasses work! High index lenses have a higher index of refraction than regular lenses, which means they don’t need to be as thick around the edges to be effective.

High-index lenses mean that the lens itself can be both thinner and lighter. This allows your glasses to be as fashionable and comfortable as possible. High-index lenses are particularly beneficial if you have a strong eyeglass prescription for nearsightedness, farsightedness, or astigmatism. However, even those with a low eyeglass prescription can benefit from high index lenses.

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

Believe it or not, but today, almost everyone is a victim of Computer Vision Syndrome (CVS), a condition which results from focusing the eyes on a computer or any gadget for prolonged hours. Continuous working on digital screens means focusing and refocusing your eyes back and forth. This leads to eyestrain, dry and sticky eyes.

The Benefits of Blue Cut Lenses

Blue Cut Lenses is to block and protect your eyes from high energy blue light exposure. 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.

Why We Need The Blue Cut Lens?

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 use mobile devices, and teens are spending an average of 6.5 hours per day on screens. Now that kids are using more digital devices at home and school starting at a young age, it’s important to protect their eyes as much as possible.
