Hi, I hope you can answer this question that is baffling me.
I now require spectacles for driving; anything more than 20 feet away is a blur.
But my near vision is perfect, so fine print from a book is no problem.
So why, without my spectacles on and looking in a rear-view mirror, which is approx 16 inches away and at head height, are the number plates of the cars behind blurry?
If I then put my new specs on the number plates are perfectly clear.
I tried my own off the cuff experiment, and stuck a sticker on the rear-view mirror with some writing on it, and without glasses it was perfectly clear, when I tried my specs the sticker’s text became distorted.
Thank you in advance
