Liquids known as ferrofluids could potentially help to improve people"s vision by being used in adaptive lenses, it has been claimed.
According to a study carried out by Rensselaer Polytechnic Institute in Troy, New York, using ferrofluids as "liquid pistons" could theoretically help to make adjustable liquid lenses with perfect spherical interfaces, the RSC reports.
These would then be used in applications including phoropters, which are used by optometrists to measure the way in which light is focused on the eye and help professionals to prescribe contact lenses and glasses.
Commenting on the study, Nicole Pamme, an expert in microfluidics from the University of Hull, told the RSC: "Without any moving parts inside the device, one can control a lens quite accurately and precisely just by moving something else in a different position."
In other research, the new ClearKone hybrid contact lens has been developed by SynergEyes and helps to correct blurred and distorted vision, a common symptom of keratoconus, which affects one in every 1,000 people.
