Hi Lamont D, I have glasses but now need 3 or 4 different pairs to take around with me.. My normal ones, when the vision is good. A pair with one covered lens for blurred vision. Prescription sunglasses that have a black patch for one eye. A pair containing a prism that proved useful for the first time I had the double vision as the images were so far apart that it was able to rein one side back. However the double vision I'm getting now fluctuates with my diet and the prism no longer works for me. Sometimes its just a matter of closing one eye (either one) but that leads to a stress/tension headache.
