What are high index lenses?

Benefits And Considerations Of High-Index Lenses

It's not always the easiest and quickest task to find the perfect pair of specs for you… a great place to start when looking is to consider all your needs so you can easily narrow down the never-ending selection of frames and lenses. As much as your glasses look as good as possible, they also need to correct your vision to the best of their ability and feel as comfortable as possible! Discover what the fuss about high index lenses is, and all the benefits that come with choosing them…

Unveiling High-Index Lenses

High-index lenses are a technological advancement in the field of eyewear that addresses one of the most common concerns: lens thickness. Traditional eyeglass lenses, especially for individuals with strong prescriptions, tend to be thicker at the edges, which not only affects aesthetics but also comfort. High-index lenses tackle this problem by using materials that have a higher refractive index, meaning they can bend light more efficiently and require less material to achieve the same corrective power. This results in thinner, lighter, and more aesthetically pleasing lenses.

The Benefits of High-Index Lenses

• Reduced Thickness and Weight: The most significant advantage of high-index lenses is their ability to provide strong prescription correction without the bulky appearance. These lenses can be up to 50% thinner than conventional lenses, making them an ideal choice for those with high prescriptions. Not only does this enhance your overall appearance, but it also reduces the discomfort often associated with heavy glasses.
• Visual Clarity: High-index lenses effectively reduce a phenomenon known as chromatic aberration, which can cause colour fringing and distortion around the edges of conventional lenses. The improved optical properties of high-index materials result in sharper, clearer vision across the entire lens surface.
• Enhanced Aesthetics: Thinner lenses contribute to a more streamlined and modern look. Whether you're choosing prescription glasses or sunglasses, high-index lenses allow for more design versatility and a broader range of frame styles to complement your personal style.
• Better UV Protection: Some high-index materials inherently offer better UV protection, safeguarding your eyes from harmful ultraviolet rays. While not all high-index lenses have built-in UV protection, it's worth exploring options that offer this additional benefit.
• Reduced Distortions: High-index lenses exhibit reduced distortion and aberrations compared to conventional lenses. This means that your vision will be more accurate and natural, allowing you to enjoy your daily activities without unnecessary visual disruptions.

Considerations and Variations of High-Index Lenses

While high-index lenses offer numerous benefits, it's essential to consider a few factors before choosing them:

• Cost: High-index lenses often come with a higher price tag due to the advanced technology and materials used in their production. However, their benefits in terms of comfort and aesthetics can often justify the investment.
• Prescription Strength: While high-index lenses are advantageous for strong prescriptions, individuals with milder prescriptions may not experience as significant a difference in thickness or weight compared to traditional lenses.
• Coatings and Add-Ons: Just like traditional lenses, high-index lenses can be paired with various coatings such as anti-reflective coatings, scratch-resistant coatings, and blue light filters. These enhancements further improve your overall visual experience and lens durability.

No one wants to feel weighed down by thick and heavy glasses … high index lenses are a step in the right direction to avoiding just that!  Although the cost might not be the most budget friendly option, it can be argued that these lenses are worth the investment especially for high prescriptions, due to them being able to make wearing glasses significantly more enjoyable! If you want to further protect your eyes from the UV rays, look great and hardly notice your glasses sitting on your face, these could be ideal! You deserve to have access to optical clarity without having to compromise on your looks or comfort… check out your options today!
