06/23/2023 – Bangor, PA: 1.80 High index 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
These are comfortable to wear because they are thin and light. They are also more attractive and transparent than standard lenses. This is especially true when combined with anti-reflective coating. They also allow more light through the lens to enter your eye, improving clarity and vision.
You may benefit from a lens with a higher index, depending on the strength of your prescription. However, some people are concerned that they will be thick and bulky. Fortunately, you can find many frames that can accommodate high-index lenses. You can even find some rimless or 3 piece mount frames that can support these 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 several different indexes, but plastic only goes up to 1.74 index. A 1.74 index reduces the thickness of the lens at power -8.00 but it is more expensive and does little to improve your vision.
You should typically only use a glass lens if your prescription is strong, above -7.00. Consider a lens that has an aspheric shape to minimize magnification and reduce chromatic distortions.
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. They are also 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. Bifocals or progressive lenses may also not be compatible with high-index lenses.
Glass lenses are heavier and more expensive than plastic ones. In addition, a higher index lens requires more lead which makes them more expensive to produce. Due to these factors, high index glass lenses are usually reserved for strong minus corrections that are seven diopters and 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 that have a higher index of refraction are thinner than regular lenses and can give a more pleasing 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. High-index lenses allow anyone to have lightweight, slim eyeglasses that can fit into a 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. Aspheric lenses are flatter and hide the thickness of the lens. They also look more appealing.
Most high-index lenses come with an anti-reflective layer. Your lenses will be less glare-producing, reducing eye fatigue in bright environments and making them more suitable for night driving. These lenses will also be more comfortable for those who wear their glasses long-term or are prone to blinking frequently.
Comfortable
High index lenses are thinner and 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 that is associated with strong farsighted prescriptions.
However, high index lenses aren’t right for everyone. They are more expensive than standard lenses. This is especially true if you choose to add special coatings such as anti-reflective or scratch resistant. They also have a lower Abbe value than polycarbonate and regular plastics, which can make them more susceptible to peripheral distortions. They’re also not as impact resistant as polycarbonate or regular plastic lenses. This can make them an unsuitable choice for children and active individuals.
These ultra-thin lenses are a great option for higher prescriptions (SPH +3.00 or -4.00). They are 20% thinner than polycarbonate and 30% thinner than regular lenses. These ultra-thin lenses are great for prescriptions with higher strengths (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.
