Research Indicates Opportunity to Improve Retinal Implants

Gizmodo reports that "it’s possible to restore some rough semblance of sight in the blind with artificial retinas. New research suggests that varying the length of the electrical pulses used to let a blind eye 'see' could enable much higher-resolution retinal implants, so that blind people can better navigate their environment with confidence."

Retinal Implants May Improve Sharpness of Images for Blind

"Retinal implants that deliver longer impulses may markedly improve image sharpness for blind individuals, report investigators," according to Science Digest. "Retinal implants (artificial retinas) give people with RP the ability to perceive light, using a system that includes a video camera mounted on a pair of eyeglasses, a video processing unit that transforms images from the camera into wirelessly transmitted electronic signals, and an implanted array of electrodes to stimulate visual neurons."
