For many years the solution for people with strong or complex solutions has been High Index Lenses. Available from either the High street or online stores High Index Lenses have an Aspheric design. Simply put, this means the lenses have been surfaced on one side only.
With the latest innovations in Thin Lenses technology there is now an even better solution – Double Aspheric Lenses, also known as Bi Aspheric Lenses or DA Lenses. They are different to standard High Index Lenses in that they have been surfaced on both sides of the lens. This makes them significantly flatter and thinner than traditional Plastic High Index Lenses.
Double Aspheric Lenses are a great choice for people with stronger or more complex prescriptions. The great news is that they now come in three different indexes, you can choose from Plastic 1.61 DA, 1.67 DA and super thin 1.74 DA.
There are some factors that you need to consider before deciding whether Double Aspheric lenses are the best option for you. This depends on your prescription and what you want to use your glasses for.
