I'm in the same position as Talisman, because my prescription is so high I need thinner lenses otherwise they'd look like the bottom of a milk bottle! And they're coated and have a tint to stop the glare from artificial light etc, I've just got a new pair also varifocals and can't get on with them at all, they make me giddy, I think my old ones are actually better for reading, and first of all they were too loose, now they're too tight! I really think I'm going to go back to my old ones (which I'm wearing at the moment) and get a refund on the new ones, which are, as Talisman says, over £300.
