I have been wearing eyeglasses since I was 12 years old and am now wearing bifocals. I have new glasses that work fine but I need to find a non-polarized clip-on sunglasses attachment for driving. The only one I have now is polarized and I can not see the display on the radio in my truck very well. It washes out half of the numbers and letters. I have an even worse problem with viewing any other digital display like on a gas pump or cell phone, can't see those at all unless I remove my sunglasses clip. I have looked all over the internet and am unable to find non-polarized clip -on sunglasses anywhere. I can not wear contacts so am unable to use regular sunglasses. I did a test with my wife's non-polarized sunglasses and although the display on my radio was not clear at all it did not wash out like it does with my eyeglasses and clip-ons. I have been putting up with this for a long time and would appreciate the help if anyone here knows where to buy or order non-polarized clip-on sunglasses.
