I suspect that the distance between the LED's is too small. Also, they are likely to be fairly narrow in their focus, which would be fixable. The battery life is also likely to be poor since they use tiny batteries.
I suspect that hat would just be too much trouble to be worth the purchase. However, I have seen LED glasses, with lights on the sides. I will try to see if I can find it again. It has been a long time since I've seen them.
I just found one;

However, it is also based on tiny batteries that won't last very long. Even if you aren't over 40 years old, like me, I wonder if the use of the read glasses would help things appear to be farther away, since the eye has to focus as though the screen were farther away?
