Yinhing Red And Green Glasses,Sight Focusing Convergence Training Glasses, Clip On Red Green Glasses for Children Adult, Left Green Right Red Training Eyeglasses for Amblyopia

The Yinhing Red And Green Glasses are useful for checking fabric color tones.It's easier to use these clip-on's than to hold up small pieces of colored plastic.

Whether by oversight or not, these clip-on glasses arrived without instructions. However, advice is available from many sources, and I was able to develop my own therapy. I have “Lazy Eye Syndrome”, where my eye muscles are weak, and I see double. These glasses are almost miraculous in that, by wearing them for about fifteen minutes, three times daily, they have helped to eliminate my double vision. I can only describe them as “3D glasses in reverse”, as they help each eye focus on objects and strengthen the eye muscles in a surprising short time. I did experience some problems, though, because wearing them for longer than fifteen minutes gave me headaches. As these trainers clip on to eyeglasses, and flip up out of the way, I can wear them at home and while out and around. A cautionary word is needed, however: *Never* wear these while driving; I found out the hard way that it becomes almost impossible to distinguish between a red traffic light and a green one. The arms of the clips are padded to prevent damaging eyeglass lenses, and a nice zip case is provided to safely store the focus trainers.
