“Youth” protein refreshes photoreceptor cells to protect aging eyes

Posted on by

A new study has uncovered the important role of a so-called

Scientists studying the aging process in the eye have made an important discovery around the role of a so-called “youth” protein, and shown how it promotes a cellular recycling process that maintains our vision. Experiments on mice missing this protein led to fast-tracked degeneration in the retina, indicating that the protein plays an important protective role against age-related vision loss.

Body-sucking sleeping bag may help protect astronauts’ vision

Posted on by

When astronauts stay in outer space for extended periods, they frequently develop a vision problem known as spaceflight-associated neuro-ocular syndrome (SANS). Scientists are now trying to keep that from happening, via an experimental vacuum-sealed sl… Continue reading Body-sucking sleeping bag may help protect astronauts’ vision→

Brief exposure to near-infrared light improves deteriorating vision

Posted on by

As we age, our eyesight naturally declines but a new study has found exposing our retinas to short bursts of deep red light can help deteriorating vision. The research shows just three minutes of exposure to 670-nanometer (long wavelength) deep red lig… Continue reading Brief exposure to near-infrared light improves deteriorating vision→
