My wife is a pro, she's actually in a bit of a hole over this issue. Her eyesight has changed, the focus correction on the eye piece is not working well for her now (it has limited correction range) and her glasses are in the way. Using the back screen is difficult outside because of the sun and speed. Also strength; holding a camera with a big lens at arm's length all day is hard for her. So - contacts, which she hates and her eyes react badly to. She might have to pack up, which would be very upsetting for her having built a business and because she get's a lot out of her work.
