No, expired contact lens can't be used. These are medical devices that must be sterilized and packaged in sealed containers before being sold to eye doctors and consumers. Since they touch the eye, they have the potential to harm the eye if they are contaminated. So packaged medical devices also have a expiry date as a consumer protection measure.
It is not wise to use eye drops that have expired, especially eye drops that have expired a few years ago. Expiration dates are designed to protect us as consumers, many of the ingredients in items, such as eye drops, have a shelf date and over time become stagnant or impotent. Using eye drops that are a few days, maybe even a month past their expiration date is a risk, much less using eye drops that expired years ago. If the ingredients have become stagnant or even contaminated from being stored for so long, it could cause more damage to the eye than what they drops are originally intended to fix.
