High-Index

High-index lenses make prescription glasses thinner, lighter, and more comfortable by bending light more efficiently than standard lenses. Available in 1.60 (included), 1.67, and 1.74 indexes, each lens is matched to your prescription to achieve the best balance of thickness, weight, and visual clarity.

Every lens includes premium anti-reflective, water-repellent, UV-protection, and blue-light filtering coatings, delivering exceptional value without the costly add-ons often charged elsewhere. Complete your glasses with lightweight titanium, metal, or TR90 frames for all-day comfort.

If you have a strong prescription, browse our Strong Prescription Glasses collection for frames specifically chosen to minimize lens thickness and weight.

Frequently Asked Questions

What is the difference between high-index lenses and standard lenses?

High-index lenses are made from an advanced material that bends light more efficiently. This allows them to be significantly thinner and lighter than standard lenses. They reduce the “coke-bottle” effect and provide a more comfortable, natural appearance.

Which high-index lens option (1.60, 1.67, or 1.74) is best for me?

You don’t need to choose the index yourself. When you upload your prescription during checkout, our system recommends the most suitable high-index lens (1.60, 1.67, or 1.74) based on your exact prescription power.

Generally:

  • 1.60 is included in the base price and works well for mild to moderate prescriptions. (below ±3.00)
  • 1.67 and 1.74 are recommended for stronger prescriptions to make the lenses significantly thinner and lighter. (over ±3.00 or higher)

Our experienced Korean opticians review every order to ensure the best lens thickness and optical performance for your vision needs.

Are high-index lenses suitable for everyday wear and durable enough?

Yes, our high-index lenses are specifically designed for daily use and are highly durable.

Many people worry that thinner lenses are more fragile, but that’s not the case with VionGlasses. Our high-index lenses come with multiple layers of hard coating and scratch-resistant treatment, making them significantly more resistant to scratches and impact.

Backed by advanced Korean optical technology and precise manufacturing, these lenses offer excellent durability while remaining thin and lightweight —perfect for comfortable everyday wear without compromising strength or longevity.

Do I need high-index lenses for my prescription?

High-index lenses are highly recommended for anyone with a moderate to strong prescription, as they significantly reduce lens thickness and weight compared to standard lenses.

However, they are beneficial for almost all prescriptions. Even with milder prescriptions, high-index lenses offer superior long-term comfort, sharper visual clarity, a thinner and more attractive profile, and reduced pressure on your nose and ears.

At VionGlasses, we believe high-index lenses provide better overall experience and aesthetics for most customers, which is why they are included as standard in our collections.
