Visually impaired people often experience discomfort when wearing contact lenses, which is associated with the development of dry eye syndrome.

Prolonged use of lenses causes the surface of the eyes to dry out, the blinking rate decreases, and the level of moisture evaporation increases. Thus, the cornea is at risk of damage, which causes inflammation and discomfort.

Scientists from Japan come up with a way to fix this common problem.. A team of researchers from Tohoku University developed self-hydrating lenses. They can maintain a layer of fluid under the surface of the eye adjacent to the lens..

This effect was achieved due to the fact that upon contact with the hydrothelle (of which the lens is made), a current is supplied through which a liquid is drawn from the natural lacrimal reservoir located behind the lower eyelid. At the moment, scientists are studying the possibility of wireless power lenses. Scientists plan to increase the stiffness of the lens and reduce the level of voltage required for the functioning of the system.
