Rated 4 out of 5 stars
JDPower, you're so wrong and so mentally- frozen! You can train your eyes, it is a reality.
I can be a witness both, for having tested eye training and having my sight greatly improved with various daily exercices and second, to have studied the matter in my university formation.
Of course, a lot of people can improve their sight and some can even avoid to wear glasses. But it is not good for the economy, isn't it?
This extension is a great idea, but could you add various exercices. The key for improving sight is diversity.
