Space seems to be Affecting Astronauts Usual 20/20 Vision

Well didn't we all dream about becoming astronauts as we were kids? Naught seemed more exciting than going on infinite adventures afterwards clearing those crazy tests shown in the cartoons. But growing upwards made us realize that going into space isn't so piece of cake and even if we make information technology there, information technology'south not without consequences. Some of these consequences include, deteriorating the body mass structure and making our size about 5 cm taller. Scientists discovered that infinite was really ruining the astronaut'south perfect eyesight in a very subtle style.

Something in infinite seems to be affecting astronaut's 20/twenty vision

It was establish that in approximately lxxx% of the astronauts who has longer duration space missions, a case near sightedness was reported. Even though these astronauts went to space with perfect visions, they came dorsum with strange symptoms. Well I know what yous're thinking, this could exist due to one-time age and since they came back to globe after a long time this could be a problem. While this is a very important factor, this is certainly not the reason.

Now, this problem of a non so perfect vision could exist an issue on future missions. It is important for astronauts to have a 20/20 vision and if this isn't rectified, well, this could be a trouble for those time to come plans of getting humans to Mars past the 2030s.

John Philips who was on lath the International Space Station in 2005 was the showtime to take detect of the condition and question it. During his time in space, he noticed that there was a slight deterioration in his vision. It was subtle, only information technology was there. When the doctors tested his vision, it was observed that his vision was no longer the twenty/20. Information technology was at present 20/100 later his 6 months in space. This wasn't the simply concerning factor; the structure of his optics had changed too.

The backs of his eyes had gotten flatter, pushing his retinas forrad. He had choroid folds, which are like stretch marks. His optic nerves were inflamed," reported Shayla Love of the Washington Post. NASA initially thought it was the merely case until many other astronauts complained of the same bug with vision during their time in space or on their return. This trouble is at present being referred to every bit 'visual impairment inter-cranial pressure' (VIIP) syndrome. Scientists have considered various reasons as to why this status takes place. The prevailing hypothesis states that this status acquired due to lack of gravity in space, which creates pressure inside the astronauts' head. Gravity causes fluid to exist pulled downward merely in space the fluid starts accumulating upwards. In Scott Kelly's year in infinite, an gauge of 2 litres of liquid had accumulated in his brain.

NASA is working on a solution

Scientists believe that the actress fluid in the skull could exist the event of the flattening of the eyeballs and distorting the retinas. The theory seems very satisfying but it is of import that it is confirmed. The scans aren't enough to find the problem and come up with solutions. The monitoring of the inter-cranial pressure can only be done in i of the two ways known to man, both notwithstanding, cannot be performed in infinite. Spinal tap and drilling holes in the skull are the two methods. NASA has to figure out a way if this problem is to be solved.
To counter these problems scientists are working on more and more techniques.

Currently the astronauts are required to clothing a Russian Chibis. This is a especially large pair of pants that helps reduce the pressure around the optics by sucking the air out from around the legs. This air vacuum helps stimulate gravity. The enquiry isn't very refined even so only new and new methods are being studied vigorously. Co-ordinate to John Charles, the chief scientist of NASA's Research Plan, restoring the flow seems to take some touch on on the eye. NASA is besides trying to help the astronauts have a healthier diet so that any hindrance on vision due to diet can also exist prevented. NASA seems to be thinking things through for their astronauts just in example they visit Mars sooner than expected.
