I bought some cheap varifocals and the actual reading area was to small and they wouldnt do anything about it so I had to buy another pair double the price and throw the cheap ones away so beware
trouble is when buying varifocals is you have to be careful of the size of the frame because if you have small frames the lenses are obviously going to be small and therefore not much space for both types of lenses in the one eye, hope i made myself clear, i know what im trying to say. the optician has to pinpoint where the centre of your eye is so that it is inline with the lens, fadeout do you buy varifocals online???
I wouldn`t get my spectacles from a web-site, except perhaps sun glasses as an optician can find out many health problems with an eye test, so don`t do it for your healths sake.
