(The Gist of Science Reporter) Self-moisturising Smart Contact Lenses

 [MARCH-2020]

Self-moisturising Smart Contact Lenses

• Researchers at Tohoku University have developed a novel kind of smart contact lenses which are self-moisturising, preventing eyes from dryness.
• The self moisturising system maintains a layer of fluid between the contact lens and the eye.
• The common problem with contact lenses is that they often cause “dry eye syndrome” due to less blinking and increased moisture evaporation.
• In order to tackle this problem, the researchers have developed a novel mechanism to keep the lens moist.
• The system uses Electro-osmotic Flow (EOF), which allows liquid to flow when a voltage is applied across a charged surface. The research is published in the journal Advanced Materials Technologies.
