Wearing eyeglass mounted mirrors is one of the few advantages of having to wear prescription eyeglasses at all.
I can focus on the image in
both mirrors instantly (though not simultaneously), as easily as looking straight ahead. Probably the main delay is locating the mirror while looking straight ahead, easy when it’s so close to your eye (though a possible hazard in a crash, as [MENTION=40124]ItsJustMe[/MENTION] can attest).
