Is High index lenses better than polycarbonate?

Is High index lenses better than polycarbonate?

Polycarbonate is by far the safest lens available. It’s up to 10X more impact-resistant than high-index lenses and is therefore the ideal lens material for sports protective eyewear and children’s glasses. Polycarbonate is the standard choice for almost all eyewear that requires shatter and/or chip resistance.

Are 1.6 index lenses polycarbonate?

We offer a few different indexes on our lenses. Our polycarbonate lenses have a 1.59 index which, while quite thin, is more focused on durability than lightness. Our 1.6, 1.67, and 1.74 index lenses can all be considered high index. These lenses are super-thin but are also more expensive than the polycarbonate option.

Does 1.67 high index make a difference?

1.67 high index lenses are much less costly compared to 1.74. Though both reduce the eye distortion caused by strong prescriptions (making your eyes look bigger or smaller than they are), 1.74 high index lenses accomplish this better than 1.67 high index lenses do.

Do high index lenses break easily?

High index lenses tend to be more brittle than the average pair of glasses. They may scratch and even shatter more easily than their other counterparts but there are usually anti-scratch coatings which can be added if necessary.

What is the highest index for glasses?

1.8 high index lens material is the highest level that is FDA-approved for U.S. sale and distribution. The reason for this is the more stringent impact-resistant standards set by the FDA.

Are Hi index lenses worth it?

In less technical terms, this means that high index lenses are better at bending light rays for vision correction. As a general rule of thumb, the higher a lens’s refractive ability is, the less material is needed to achieve a particular prescription strength.

Is it worth getting high index lenses?

High-index lenses are ideal for you if you are looking for eyeglasses that are lighter and thinner. If you are very farsighted or nearsighted, your regular lenses will usually be quite heavy and thick. High-index lenses bend light more efficiently, so they do not have to be as thick to be effective.

What’s the difference between high index and polycarbonate lenses?

Take a look at the video below to hear an explanation of what polycarbonate lenses are by FramesDirect. High-index lenses generally are recommended to individuals who have stronger prescriptions, so that they have the thinnest, lightest, visually appealing, and most comfortable pair of eyeglasses that they can buy.

Which is better for glasses plastic or polycarbonate?

Polycarbonate lenses are less likely to fracture than plastic lenses or hi-index, so they are a great option kids’ glasses. Essilor’s polycarbonate lenses are 20% thinner, 30% lighter, and 12x more impact resistant than standard plastic lenses. Anti-reflective treatments—such as Crizal Sapphire® 360°—can be added to Essilor’s polycarbonate lenses.

Is there an upgrade from polycarbonate to high index?

Retailers such as Warby Parker offers an upgrade from their polycarbonate to high-index for only an additional $30 for single vision, which is by far one of the most affordable high-index upgrades available out there.

What’s the index of refraction of polycarbonate glasses?

Today polycarbonate is the standard lens material for many online eyeglass retailers, and they are standard in all children’s glasses, safety glasses, and sports goggles. Polycarbonate lenses have an index of refraction of 1.59, and will generally be about 20% thinner than standard plastic lenses.
