Thinner Lenses: High index 1.80 Glass lenses can be ground thinner than standard Plastic or glass lenses. Suppose you have a High Plus or Minus Prescription. In that case, this benefits you by allowing us to make the Edge or the Center of your eyeglass lenses thinner than traditional lens Materials.
Aesthetically appealing: The higher the index of lens material, the thinner it can be made. By choosing 1.80 high index glass lenses, you can significantly reduce the thickness of your lenses, resulting in a more attractive appearance. Thinner lenses are less noticeable and can enhance your overall look by minimizing the distortion caused by thick lenses.
Improved visual clarity: High index lenses have superior refractive properties to standard lenses. This means they can bend light more efficiently, creating sharper and clearer vision. If you have a strong prescription, high index lenses can reduce the distortion and blurriness often associated with thicker lenses.
Compatibility with a range of frames: High-index glass lenses are installed into various frame types, including Metal, Plastic, and acetate frames. They are suitable for most eyewear designs, allowing you to choose frames that match your style and preferences.
Durability and scratch resistance: Glass lenses, in general, offer excellent durability and scratch resistance compared to plastic lenses. While high-index glass lenses may be slightly heavier than high-index plastic lenses, they compensate for it with their robustness and resistance to damage. They are less prone to scratches, cracks, and surface wear, which can extend the lifespan of your eyewear.
1.80 High index glass lenses are thin, light, and may help people with stronger prescriptions. However, they also cost more than conventional options.
These ultra-thin, cosmetically pleasing lenses feature aspheric curves and have a slimmer lens profile than traditional plastic or polycarbonate lenses. They are available in a wide range of frame styles and can be combined with anti-reflective and UV coatings.
Lightweight
High index lenses are thin and lightweight, making them comfortable to wear. They are also more transparent and attractive than standard lenses, especially when combined with an anti-reflective coating. Additionally, they allow more light to pass through the lens and enter your eye for improved clarity and vision.
Depending on your prescription strength, you may benefit from a higher index lens. However, some people are concerned that they will be thick and bulky. Fortunately, you can find many frames that can accommodate high-index lenses.
The index of a lens refers to how much thinner the lenses can be for a given power. Glass lenses tend to have a higher index than plastic, so they can be thinner.
However, the specific index of a lens depends on its material. Glass is available in a number of different indexes, but plastic only goes up to 1.74 index. Although a 1.74 index would reduce the lens thickness at power – 8.00, it is a lot more expensive and does not improve the quality of your vision as well.
Typically, you should only choose a glass lens for a strong prescription above -7.00. For the best possible results, you should consider a lens with an aspheric design to minimize magnification and to reduce chromatic aberrations.
Durable
Because high index lenses are thinner than traditional plastic or glass lenses, they can often be made lighter and more stylish. However, they are also typically more fragile than standard lenses and may need to be treated with greater care. In addition, they are more expensive than standard lenses. Luckily, most eye care professionals offer blue light reduction, UV protection, and anti-reflective coatings for high index lenses to help mitigate these issues.
While high index glasses can be a great option for people with strong prescriptions, it’s important to consider your frame style before selecting them. For example, rimless frames may not be able to support thin high index lenses and could cause the lens to break or crack. In addition, bifocals and progressive lenses may not be compatible with high index lenses.
While glass lenses were once the go-to for high index lenses, they have one major drawback: they’re heavy and more expensive than plastic lenses. In addition, a higher index lens requires more lead which makes them more expensive to produce. Because of these factors, glass high index lenses are typically reserved for strong minus corrections of seven diopters or more. High index plastic, on the other hand, is a very lightweight material that’s suitable for many frame styles. It also offers UV protection and shatter resistance.
Aesthetically Pleasing
High-index lenses have a higher refractive index than standard plastic (CR-39) and glass, meaning they bend light more efficiently. This allows for a thinner lens without compromising optical clarity. Lenses with a higher refractive index are less thick than regular lenses and can offer a more flattering cosmetic appearance.
In the past, a strong prescription for nearsightedness or farsightedness may have required thicker lenses that didn’t fit well into smaller frames. But high-index lenses make it possible for anyone to have slim, lightweight eyeglasses that fit well into a wide variety of frames.
Choosing an aspheric design will further reduce the thickness of your lenses, offering a noticeable difference in lens thickness when compared to regular plastic or polycarbonate lenses. This is because aspheric lenses have flatter curves that help to conceal the thickness of your lens, giving a more aesthetically pleasing look.
As an added benefit, most high-index lenses have a built-in anti-reflective coating. This means your lenses will be less reflective, reducing eye strain in bright environments, and making them better for driving at night. They’ll also be more comfortable for people who wear their glasses for long periods of time or who are prone to blinking often.
Comfortable
High index lenses are thinner, making them lighter than traditional lenses. This allows the wearer to enjoy reduced eye fatigue and increased comfort with their glasses. They also reduce the “bug-eye” look associated with strong farsighted prescriptions.
However, high index lenses aren’t right for everyone. They tend to cost more than standard lenses, especially if you add special coatings like anti-reflective and scratch resistant. They also have a lower Abbe value than polycarbonate and regular plastics, which can make them more susceptible to peripheral distortions. Finally, they’re not as impact resistant as polycarbonate and regular plastic lenses, which can make them a poor choice for children or active individuals.
The best choice for your eyes and budget is to go with a 1.67 index lens – they are 20% thinner than polycarbonate lenses and 30% thinner than regular lenses. These ultra-thin lenses are a great option for higher prescriptions (SPH +3.00 or -4.00). They can be used in either semi-rimless or full rim frames, but you’ll want to choose full rimmed frames to keep the lenses safe from accidental damage or loss. They’re also slightly more fragile than other materials, so they require a bit more care when handling your lenses.
