Product Description

What’s the Difference Between 1.67 and 1.74 High-Index Lenses?

1.74 high-index lenses are up to 10% thinner than 1.67 high-index lenses. Both have a high index of refraction and can accommodate strong prescriptions, but 1.74 high-index lenses are for especially strong ones: +/-8.00 or higher.

What Are the Advantages of High-Index Lenses?

• They’re thinner, lighter, and less obtrusive within frames, unlike thicker lenses that may protrude outwards. Lower-index lenses can also magnify or shrink the appearance of your eyes, which is not as much of a risk with high-index lenses. .
• They’re versatile. High-index lenses can be single-vision, progressive, and even light-responsive. You can also opt for high-index lenses that filter blue light, and if you’re getting sunglasses, polarized high-index lenses are an option, too. No matter how you’d like to customize your prescription lenses, it’s a good bet that high-index lenses can play along.
• They fit most frames. Your choice of frames won’t be restricted by high-index lenses: Their thin profile enables them to work with many frame styles if you have a higher prescription. (We recommend choosing a frame that centers your eyes behind each lens to reduce the thickness of your lenses. The stronger your prescription, the more important this is! Bigger frames = thicker lenses, regardless of the refractive index.)
• They’re comfortable. High-index lenses won’t sit heavy on your nose and ears, and they’re at less risk of sliding down than thicker lenses.

Are High-Index Lenses Worth It?

So: Should you get high index lenses? If their aesthetics appeal to you, high-index lenses are a great way to get the thinnest lenses for a high prescription. When compared to lenses with a lower index of refraction, their benefits outweigh the bump in cost for many wearers.

Interested? Check with your eye doctor or optician, and see if high-index lenses are right for you.
