New eyedrops could repair corneas, make glasses unnecessary

“This is a new concept for correcting refractory problems.”

A Shaare Zedek Medical Center and Bar-Ilan University ophthalmologist has invented and patented “nanodrops” which – when placed on pigs’ corneas – have produced improvements in short-sightedness and long-sightedness.

If they improve vision in humans when clinical testing is carried out later this year, the nanoparticle solution could eliminate the need for eyeglasses, Dr. David Smadja said on Wednesday.

Larry Hester is the 7th person in the U.S. to have a bionic eye implanted.

Thanks to bionic eye technology, people diagnosed with a degenerative eye disease are seeing a new future. And Larry Hester is the seventh person in the U.S. to have a so-called bionic eye – an Argus II Retinal Prosthesis Device — implanted. It allows him to see for the first time in 33 years.

Contact lenses that give you telescopic vision

A prototype contact lens-and-glasses system that lets you zoom in on something to 2.8X magnification.

New contact lenses have been created that when paired with special spectacles, bestow telescopic vision on their wearers.  The contact-lens-and-spectacles combination magnifies scene details by 2.8 times.

Study of brain’s visual center finds men and women really do see things differently

Men and women do see things differently.

New research published in BioMed Central’s open access journal Biology of Sex Differences finds that the way that the visual centers of men and women’s brains works is different. Men have greater sensitivity to fine detail and rapidly moving stimuli, but women are better at discriminating between colors.

Scientists restore sight to blind mice by regenerating optic nerve

Scientists restore vision to blind mice.

There are three blind men who have an inherited eye disorder that had destroyed the light-sensing cells of their retinas many years ago.  Now one of the blind men can walk around at night navigating by streetlight and headlights.  Another can read his own name.  And the third mean has been able to see his fiancée’s smile for the very first time.  All of this has been made possible by the retinal implants they have been fitted with.  The implants took over from the broken cells.  They sense incoming light by converting it into electrical impulses delivered to the brain.  They aren’t close to having 20/20 vision, but they have restored sight to people who have lived without it for years.

A revolutionary new treatment, involving an operation to insert a plastic implant into the eye, could allow millions to abandon their spectacles.

Needing to wear reading glasses is one of the signs of reaching middle-age.
