I'm 2.25 distance right eye, 2 in left and now in addition 1.75 near I'm both.
I want to get a pair of varifocals. As I intend to wear them for flying only should I get them tailor-made? Where does the grading line go? Does a polarised coating help on the sunglasses version?
There is no grading line with varifocals : the lens strength changes seamlessly: Take your chart to the optician with you: and tell him what you want.
The problem will be if you have a large correction 2.25 is pretty big, mainly with peripheral vision.
There is a post by me on another thread about problems with tripping up kerbs and steps, on looking down with large correction varifocals.
Don't get polarised sunlenses, you will get interference on the screen and some of the dials; in fact think hard about getting either separate prescription sunglasses or 'flip up' detachable sunlenses if you can't stretch to two pairs
I made the mistake of getting varifocal photochromic sunglasses for flying/ driving which of course don't work as the screen filters out the u/v required to activate the photochromic change.
IMHO varifocals are worth spending a bit of money on, especially if other lens problems like astigmatism are present.
