Choose the right lens index
Understanding Lens Index: Which Is Right For You?
Welcome to the world of optical lenses! If you're new to selecting eyewear, you might have come across terms like "lens index" and wondered what they mean. In simplest terms, the lens index refers to how thick or thin the lens is. When you hear numbers like 1.56, 1.61, 1.67, or 1.74, they represent different lens thicknesses – with higher numbers signifying thinner lenses.
Why does this matter? The lens index you choose can affect both the appearance and comfort of your glasses, especially if you have a strong prescription. Here's a brief overview along with recommended prescription ranges for each:
1. Standard Index lens 1.56:
- Recommended SPH Range: +/- 0.00 to +/- 3.00
- Recommended CYL Range: 0.00 to -2.00
- 0 euro addition
This is a standard lens thickness suitable for many people with mild prescriptions. These lenses can provide clear vision without adding unnecessary weight or bulkiness
2. High Index Lens
2.1 Advanced 1.61:
- Recommended SPH Range: +/- 3.00 to +/- 6.00
- Recommended CYL Range: -2.00 to -3.00
- 29 euro addition
A step up from the standard, these lenses are thinner and lighter. They are a good choice for those looking for a more streamlined look without compromising on clarity.
2.2 Premium 1.67:
- Recommended SPH Range: +/- 6.00 to +/- 8.00
- Recommended CYL Range: -3.00 to -4.00
- 49 euro addition
Even thinner than the 1.61, these lenses cater to those with moderate to high prescriptions, ensuring your glasses don't appear overly thick.
2.3 Super premium 1.74 Index:
- Recommended SPH Range: +/- 8.00 and above
- Recommended CYL Range: -4.00 and above
- 69 euro addition
The thinnest lens in our lineup, ideal for those with high prescriptions, preventing the "coke-bottle" effect and giving a sleek appearance.
It's vital to remember that while higher index lenses are thinner and often more aesthetically pleasing, they also come at a premium. However, even if you have a low prescription, there's nothing wrong with choosing a higher index if thinness is a priority for you. It's all about finding the right balance between appearance, comfort, and budget.
