It's probably the thing we all take for granted: we can see.
However, Gene Purdie can not see and his life is much different than any of ours.
He has a condition called Stargardt's disease - it only allows Gene to see the outline of things in front of him. That was until TV host Rachael Ray invited him on her show for an incredibly special segment.
Rachael gave Gene with a pair of eSight glasses which will help is vision. After moments of having them on, he immediately looked over and saw his wife! Everyone was crying... so are we!
