There are so many new apps around from mortgage rates to video games. This new app developed by Bigad Shabaan helps the visually impaired to negotiate around in the real world by having others people guiding them by cell phone.
If a blind person is at the grocery store and is diabetic for instance, the blind person can hold his cell phone up to the item he wonders is healthy for him and connect with another person anywhere in the world to help! That’s awesome huh?

It’s wonderful that we have people like Bigad Shabaan thinking in these new directions for technology to help those less fortunate feel integral in society.
Contact lenses are wonderful innovations that bring joy and freedom from eyeglasses to many. Like wearing seat belts are an agreed upon safety measure, there are also important safety measures to take when wearing your contact lenses.
Following these few steps can lessen any problems and infections that could occur from wearing your contacts.
These are the most important steps:
1) wash your hands with soap prior to handling your lenses.
2) air dry your case every time you use your lenses.
3) use proper disinfecting/multi -purpose solutions and replace ALL the solution every time you open the case – do NOT merely ‘top off’ the existing solution. If you don’t wear your lenses for longer than 1 week then open and replace the solution.
4) replace your case at least every 3 months
5) Dispose of your lenses on schedule and do NOT wait until they feel uncomfortable!! Following these few simple rules will keep your lenses clear and comfortable and your eyes healthy.
For years now, we have all enjoyed and awed at the accomplishments of NASA and our space flights. Recently, Mike Wald reports at Space.com that there may be serious eye issues with astronauts in space over extended periods of time. Specifically, the fluid inside our brain and down within our spine develops increasing pressure that extends through the optic nerve and ‘pushes’ on the delicate retina.
This is medically denoted as Papilledema.
Papilledema can put so much pressure on the optic nerve ( see arrows in picture) that the fibers carrying the image to the brain just die and cease to function.
Of course, that has serious consequences for healthy vision. Right now, they have already determined that many of the astronauts in space for long durations show mild forms of this condition.
What scientists are now wondering is if there is a way to counteract this process and just why it is happening. This problem will need to be understood and resolved before NASA undertakes long missions like to Mars for example. Let’s hope they can find a solution as human space exploration always holds a special place for all of us. If not, then perhaps our continued robotic missions will suffice or we will develop Artificial Intelligence in our robots which could bring back some ‘human’ qualities of adventures in space.
