Researchers from St Andrews University believe that creating a contact lens that gives its user perfect vision may soon be possible.
A new technique has been developed by the scientist from the university, consisting in separating the meta-atoms from their substrate and subsequently putting them together and thus producing a new, almost visible, flexible material, called Meta-flex. Dr Andrea Di Falco, who led the study, assures that the material may be used to create novel contact lenses.
Meta-flex may be turned into smart fabrics, which – when put on the surface of soft contact lenses - could substantially improve their characteristics and provide their wearers with perfect vision. These lenses will be free from any deficiencies, such as aberration or limited resolution, found in currently available contact lenses.
It is yet not known when the new material will be ready for commercial application, but the researchers are confident that it will happen soon.
