I have been experimenting with the tool below and i find that it helps me see more clearly.
I wanted to share this and get feedback from you guys if it helps you too.
How i use the tool:
The tool is located here: http://jsfiddle.net/gux73b5d/7/
Enlarge the part that has the moving letters in it so it will fill as much screen area possible
While i am using my differential glasses, doing computer work, i keep a browser tab open with this tool running. Every now and then i follow the moving letters and try to get them to focus using active focus and blinking.
At first when i used this tool it made my eyes hurt a bit.
I have been using it for a few days now and already seeing improvement in my cm measurements and visual acuity.
Please send your feedback, it is interesting to know if it helps more people.
