Contact lenses start out as a liquid plastic (one that’s formulated and optimized for vision correction). The plastic is poured into molds and cured to form tiny little pucks. These are then shaped on a lathe to exacting specifications. At this point your contact lens looks much smaller than when you put it in your eye because it is dry. The dry little contact lenses are dropped into the lens blister, sterile saline is added and the foil is sealed on top. The lenses in the blisters are packaged and set aside while the lenses hydrate to their full size and get soft. They are all put in quarantine until they pass rigid quality control inspections. They are then shipped to retailer and distributors.
