Hi Steven;
Oh well, may some one should have told that to The Great Khan.....if they dared.
I have a question about Optivisors....Given that Optivisors are a generic tool and not optometrically customised to an individual's eyesight, is there a danger we are doing our eyesight more harm than good if we use them?
I use my relatively new reading glasses for close work...and am now less clumsy as a result.
All the Best
Neil
