The cost of multifocal contact lenses
Multifocal Contact Lenses cost more than single focal contact lenses. This is because of the fact that they are more difficult to make and that they are relatively a new concept. Chances are multifocal contact lenses will always be more expensive than the others unless you can find them on sale.
This should come as no surprise if you wear multifocal glasses. You pay more for your glasses than you did when you only needed a single prescription for your lens because the lenses for your glasses are more difficult to make. The same is true with multifocal contact lenses.
