I printed out an eye chart and have consistent lighting in a room where I use it. My eyes have not improved in the past 5 years of doing exercises on and off.
I recommend printing an eye chart and testing yourself w/ the same lighting and distance from the chart.
Also, keep me updated please (if you remember to, post here or something), genuinely interested.
I am tempted to buy a huge screen and place it across the room from me to have the focus point further away.
I think part of the problem might be that it's focused on one place, rather than close focus. But I guess it's better to be focused further away.
