I don't, but should for reading in poor light. The small print on some curry tins is beyond me - made worse because it's usually 1 point dark orange print on a purple background. Peripheral vision (nearly 180 degrees) and long sight is good - I can easily make out 2mm thick twigs on trees over 50 feet away. My eyes are over 55 years old. My liver's still good . I expect things to go downhill from here
