WEB VISION TECHNOLOGIES ANNOUNCES THE VISION FOR MARS PROJECT TO HELP NASA PROTECT THE VISUAL HEALTH OF ASTRONAUTS

Web Vision Technologies is working closely with National Aeronautical Space Administration (NASA) to develop an “All-in-One” vision testing (diagnostic) device that can be deployed on spacecraft to do comprehensive vision testing, evaluation, and to guide medical interventions of astronauts experiencing vision problems on future long-duration, deep space missions. There is limited room for vision testing […]

NOVEL TECHNIQUE TO EXAMINE CREW HEALTH IN ORBIT PROVIDING INSIGHT

The reason why some International Space Station astronauts have returned to Earth with changes in their vision has been a mystery, but new noninvasive techniques to examine crew health in orbit may provide researchers with much needed insight into the problem. A number of astronauts who have returned to Earth after long stays aboard the […]

ONE CARBON METABOLISM ON THE SPACE STATION

It has been known for some time that time in space affects astronauts’ vision. Post-flight vision changes have been reported by many astronauts after they spend time on the International Space Station. Many, but not all. But why are only certain people affected by spaceflight in this manner?’ Results of a new study involving 49 […]

NASA STUDIES LINK GENETICS AND NUTRITION WITH ASTRONAUT VISION CHANGES

Recent research findings from the International Space Station show there may be a link between nutrition, genetics and vision problems experienced by some astronauts. Earlier reported findings from blood samples collected on the space station suggested chemical differences in astronauts with vision issues. Scientists conducted a follow-on study to identify genetic markers that help code […]

AN ORANGE A DAY KEEPS SCURVY AWAY

Centuries ago, ships often sailed with crews numbering in the hundreds returning with tens. Cause of death: Scurvy – a severe depletion of Vitamin C. Today’s explorers cross miles of space with no hope of finding an island with food and nutrients along the way. All nutritional needs must be met aboard. “Nutrition is vital […]
