What Are Multifocal Contact Lenses â And Should You Order Them Online? The first sign that you may need multifocal contact lenses is if your prescription for glasses has numbers in the ADD column. Numbers in this column indicate that you are presbyopic to some extent. Although there is no set limit to what the ADD number can be, it usually ranges between +0.75 to +2.50. The higher your ADD number is, the more you stand to benefit from multifocal contact lenses. But more importantly than the ADD number, is how bothered you are by your vision up close.

- Most people choose to have their monofocal lens set for distance vision and use reading glasses for near tasks. Alternatively, a monofocal lens can be set for near vision, but glasses or contact lenses are then required to see objects clearly at a distance. A blending of these two approaches is also available for individuals undergoing cataract surgery or natural lens replacement in both eyes.

- The most common way is to perform LASIK or an ASLA procedure, where one eye is focussed for distance and one for near vision. If monovision is achieved via a surgical lens procedure, one artificial lens set for distance vision will be implanted, while the other lens will be set for near vision. In some cases, only one eye will need to be adjusted to create monovision/blended vision.
