One of the most successful marketing strategies is to offer a complete portfolio of products that will cover any demands from the final user. As you have seen in the previous section, with the Alpha Series your company will be able to cover the highest market segment with high performance customizable lenses. Now, with the Basic Series you will also have the chance to offer a basic product with an intermediate position in your portfolio, a product that could be offered to a less demanding clientele, so finally, you will have potential to satisfy different market segments with good quality products.

Basic Series is a group of progressive designs in several progression lengths that have been calculated using the Surface Power technology, this means no personalization. This calculation method provides the final lens with the power prescribed to the wearer without considering the different face parameters and frame data.
