A team of Korean researchers has developed graphene-coated contact lenses that can protect their wearers from electromagnetic radiation and dehydration. It’s not immediately obvious what are the practical implications for this technology, but it’s certainly intriguing.
The graphene-coated lenses were tested for their ability to shield radiation by positioning egg whites below these lenses and placing them inside a microwave. Blasting the eggwhites with microwave radiation led to the contact lenses simply converting the microwaves into heat that dissipated into nearby air. The egg whites themselves remained uncooked and therefore kept safe from the radiation.
The lenses also prevent evaporation from drying out the eyes. This was tested by capping vials containing water using the coated lenses. The evaporation was effectively halted.
