Over the years, contact lenses have seen many upgrades and improvements. From the materials that are used to the way they are made, the quality and comfort has continued to improve. The first contact lenses were made from blown glass which only allowed for a few hours of use. Today, they are made with innovative hydrogels that retain moisture and fit comfortably all day long. Recently, researchers at MIT have discovered a new way to prevent hydrogels from dehydrating. Hydrogels are the starting point for which many contact lenses are made. The new method will bind the hydrogels to elastomers
