Choosing the right type of prescription lens depends on both your vision correction requirements and how you use your glasses. Prescription lenses fall into two main categories, single-vision and multifocal. Your choice will depend on whether you need correction for one distance (near or far) or a single multifocal pair for multiple distances and activities.

High-Index 1.74 lenses are thinnest possible for strong prescriptions. 1.74 Index lenses bend light to a greater degree which in turn means that less material is used to attain the desired vision correction. The biggest effect of having to use less material is that the lenses become much lighter and thinner.
