New App Helps Visually Impaired

Visually Impaired Person in Grocery Store

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.

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.

New Treatments for Dry Eyes

Nanoparticles to treat dry eye syndrome

Nanoparticles to treat dry eye syndrome

Dry eye syndrome is commonly treated by applying drops several times a day. Canadian researchers have now developed a topical solution containing nanoparticles that provides the eye with moisture for several days. Their study was presented in “Nano Research”.

Scientists at the University of Waterloo infused biocompatible nanoparticles with Cyclosporine A, the drug also found in eye drops. They made the nanoparticles stick to the eyeball for longer periods of time and progressively deliver the right dose of the drug. After five days, they are absorbed by the body.

Due to the fact that the particles stay on the eye and are not washed out like normal eye drops on account of the eye’s ability to self-cleanse, only a fraction of the drug – five per cent – compared to eye drops, are required. This also prevents irritation and reduces the risk of toxic exposure due to excessive use of eye drops, says study leader Shengyan Liu. Clinical trials using the nanoparticles are planned.

There are many other ways to help with dry eyes. Lubricant eye drops are the mainstay of dry eye therapy – however there are many other ways to improve comfort.

Eyes In The Sky

space programFor 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.     optic nerve edema

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.
