Why do lenses vary in price when they all look the same? They are highly technical products that in many cases will require a greater investment than your frames. As the many built-in benefits are not visible at a glance, it can be hard to compare like for like.

Thinner and lighter lenses

Lens index determines the thickness and weight of your lenses. 1.50 index (or CR39) is the base option and the one advertised in most package deals.

Lenses for vision correction

The other big factor differentiating between lenses is the type of vision correction they are designed for:

Multifocal lenses allow multiple distance correction with no visible lines, making them the most convenient solution for many viewing distances. While this lens type can be more costly due to their complexity, the latest sophisticated designs will deliver more seamless and natural vision, less distortion, and provide greater flexibility in frame choice over standard options. There are three types of multifocals:
