What you should know about Contact Lenses Expiration Dates

All contact lenses including multifocal lenses have an expiration date.

Usually, the soft contact lenses are packaged with a foil cover to seal the containers. The containers are then filled with non-preserved saline, and an additional wetting agent to keep the contents in the package remain fully hydrated until the user opens it.

The foil cover contains not only the manufacturer information, it also contains information such as the lens brand name, lens material name, lens power, lens diameter, the lens expiry date, etc. the expiration date is written in yyyy/mm format, meaning that the year that the lens will expire comes first followed by the month.
