I find varifocals difficult, because your horizontal range of vision is very limited, and to the centre of the lens So scanning a page is a pain because you can't swivel your eyes across the page, becaue you get out of focus, and I find having to swivel my head back and fore to read a line of text irritating. I am on my first pair, and don't use them very much, preferring to use my other pair (reserves).
That's true but it rather depends what you're doing. Recently I prefer my contacts resorting to reading glasses but I found doing a nav' assessment a week or two back that keeping a running track on a map was impossible that way, only varifocals let me micro nav' to the degree I wanted.
The real problem will be that as your eyesight is deteriorating you'll find varifocals with enough tint to be safe skiing will be allowing so little light in that you'll have problems seeing sometimes which sucks. I tested some varifocal contact lenses which were hopeless in the mountains, you need so much light to hit them for them to work that it's impossible to wear decent sunglasses.
it's a pain, prolonged use of the wrong sort of optics will irreparably damage your eyes so it's important get something decent, i.e. the right UV protection, the right tint and the right prescription if you need that.
