We measured a.c. admittances for isolated rat lenses over a wide frequency range of 100 Hz to 500 MHz. In order to evade electrode polarization at low frequencies, we examined extracted lenses by direct semi-squeezing with Pt black-coated platinum electrodes. This gave rise to a 10(6) increment in permittivity at low frequencies, and two distinct dielectric(More)
To correlate the formation of cold cataract with changes in the passive electrical properties of the lens, we measured impedances of isolated rat lenses in the frequency range from 100 Hz to 500 MHz. Temperature-dependent, reversible changes were confirmed in the dielectric behavior as well as in the histological characteristics. The impedance of lenses(More)
