Some do some don’t. You’d need to read the website to know.
Sorry bad phrasing on my part. What i meant was the line that the change occurs. It’s not a line on the lens as they are blended together but is a point the lens swap over. The Optitions will measure and setup the lens change point depending on your eyes and how the frame chosen sits in your face.
thanks my first questions was on trying frames out, can we try and resend frames and try more or that exp. is only in high street stores?
There are no change lines with varifocals, you’re thinking about bifocals that have a visible line where distance and intermediate/reading lenses join. Varifocals are a smooth progression through different degrees and take a while to get used to when going from single vision lenses. In my experience I’ve never seen varifocals online go for less that £60 plus the cost of the frames. If anyone knows anywhere that proves me wrong on that then (please) post a link.
