At Nations Optics, we believe customers should receive better lenses as standard. That’s why we provide a minimum lens index of 1.56, giving you lenses that are thinner and lighter than basic 1.50 lenses.
Many optical stores still offer 1.50 index lenses as their basic option. Nations Optics takes a smarter approach by starting at 1.56 index as the minimum standard for many lens selections.
This means your lenses are naturally slimmer, more comfortable and better looking compared to older thick standard lenses.
Based on your prescription power and selected lens type, Nations Optics may automatically upgrade the lens index to 1.59 or 1.61 wherever suitable.
This helps ensure you receive the most practical lens thickness without needing to manually understand technical lens materials.
A lightweight and durable option often used where extra thinness and strength are beneficial.
A slimmer premium choice for stronger prescriptions needing better comfort and appearance.
Lens index affects how thick or thin your glasses lenses appear. Higher index materials bend light more efficiently, allowing lenses to be made thinner.
While everyone can enjoy lighter lenses, higher index materials are especially useful for customers with medium or high prescriptions.
Instead of giving every customer the same old basic lens material, Nations Optics focuses on matching lens thickness with your prescription needs. This creates a better visual result and improved wearing comfort.
If you’re asking what lens index Nations Optics provides, the answer is simple: a minimum 1.56 index as standard, with possible upgrades to 1.59 or 1.61 depending on your prescription and lens type. That means thinner, lighter and smarter lenses designed around your needs.
