1. What are those 1.56, 1.59,1.74 etc?

These are different indexes of lenses. Simply put, these values determines the lens thicknesses. The higher the index, the thinner the lenses will be.
For example, if your power is -5.00, you could expect a thicker lens if you choose 1.56 index. The ideal indexes are 1.59 or above for a power like -5.00 to reduce the lens thickness.

2. Which index is best for me?

Here’s a general rule.

Total power Up to +/-3.00 : Choose 1.56
Total power between -3.00 & -4.00: Choose 1.59,1.60
Total power between -3.50 & -6.00 : Choose 1.67
Prescriptions beyond -6.00 : Choose 1.74

Calculating total power.

Just add up the values in both SPH (Sphere) & CYL (Cylinder) columns together to get the total value. As you can see, the total power of the Right eye is -7.00, and of the left eye is -8.00 in the above example.

Please note, this is a general rule to follow and we cannot give any guarantee about the lens thickness for a high prescription as there are several other factors influence the thickness.

*If you are choosing a large/oversized frame, try to choose an index higher than recommended to get the best results.
