If you wear glasses, you know how important it is to have lenses that are comfortable, lightweight, and provide clear vision. That’s where high index eyeglass lenses come in. These lenses are designed to be thinner and lighter than traditional lenses, making them a popular choice for those with strong prescriptions. In this article, we’ll explore the benefits of high index eyeglass lenses and why they may be the right choice for you.
What Are High Index Eyeglass Lenses?
High index eyeglass lenses are made from a special type of plastic that is able to bend light more efficiently than traditional lens materials. This means that high index lenses can be made thinner and lighter while still providing the same level of vision correction. They are available in a variety of indexes, with higher indexes being thinner and lighter than lower indexes.
Thinner and Lighter Lenses
One of the main benefits of high index eyeglass lenses is their thinness and lightness. Traditional lenses, especially for those with strong prescriptions, can be thick and heavy, causing discomfort and making the glasses feel bulky. High index lenses, on the other hand, are significantly thinner and lighter, making them more comfortable to wear for extended periods of time.
This is especially beneficial for those with strong prescriptions, as high index lenses can reduce the “coke bottle” effect that can occur with traditional lenses. This not only improves the appearance of the glasses but also makes them more comfortable to wear.
High index lenses are also a great choice for those who want a more aesthetically pleasing pair of glasses. As mentioned, high index lenses are thinner and lighter, making them less noticeable on the face. This can be particularly beneficial for those with strong prescriptions, as traditional lenses can make the eyes appear smaller or distorted. With high index lenses, the eyes will appear more natural and in proportion with the rest of the face.
Better Vision Correction
High index lenses are able to provide the same level of vision correction as traditional lenses, but with less material. This is because the material used in high index lenses is able to bend light more efficiently, allowing for a thinner lens. This is especially beneficial for those with strong prescriptions, as traditional lenses can become quite thick and heavy, causing discomfort and distortion.
Additionally, high index lenses are able to correct a wider range of vision problems, including astigmatism and presbyopia. This makes them a versatile option for those with complex vision needs.
Many high index lenses come with built-in UV protection, which can help protect your eyes from harmful UV rays. This is especially important for those who spend a lot of time outdoors, as UV exposure can lead to eye damage and even vision loss. By choosing high index lenses with UV protection, you can ensure that your eyes are protected while still enjoying clear vision.
Are High Index Lenses Right for You?
High index lenses are a great option for many people, but they may not be the best choice for everyone. Here are some factors to consider when deciding if high index lenses are right for you.
High index lenses are most beneficial for those with strong prescriptions. If you have a mild prescription, you may not notice a significant difference between high index lenses and traditional lenses. However, if you have a strong prescription, high index lenses can greatly improve the comfort and appearance of your glasses.
If you lead an active lifestyle or participate in sports, high index lenses may be a good choice for you. Their thinness and lightness make them less likely to slip or fall off during physical activity. They are available with blue light protection for those who spend a lot of time in front of digital devices, Transitions for those who like the convenience of sunglasses and clear glasses all in one pair, tinted and polarized options for sunglass wearers, and are even available in progressives.
Types of High Index Lenses
High index lenses are available in a variety of indexes, with higher indexes being thinner and lighter than lower indexes. Here are the most common types of high index lenses:
1.6 index lenses are the most common type of high index lenses. They are thinner and lighter than traditional lenses, making them a popular choice for those with strong prescriptions. They are also more impact-resistant than traditional lenses, making them a safer option for those who are prone to dropping or damaging their glasses.
1.67 index lenses are even thinner and lighter than 1.60 index lenses. They are a great choice for those with very strong prescriptions, as they can reduce the “coke bottle” effect even further. They are also more expensive than 1.60 index lenses, so it’s important to consider your budget when deciding which index is right for you.
1.74 index lenses are the thinnest and lightest high index lenses available. They are a great choice for those with extremely strong prescriptions, as they can provide the same level of vision correction as traditional lenses with significantly less material. However, they are also the most expensive type of high index lens.
Caring for High Index Lenses
High index lenses require the same care as traditional lenses. Here are some tips for caring for your high index lenses:
- Always clean your lenses with a microfiber cloth to avoid scratching.
- Avoid using harsh chemicals or abrasive materials on your lenses.
- Store your glasses in a protective case when not in use.
- Avoid leaving your glasses in extreme temperatures, as this can damage the lenses.
