How Thick would a 1.57 index lens be?

My current lens is standard 1.5 and they are a little thick for me, about .5 inches thick. I am thinking of 1.57 index, Can anyone give me a little perspective on this matter or how much will it be thinner than 1.5 index lens?

    It will depend on your prescription and the size of your frame. You'd better go to your optometrist to have it measured.

    It should depend on how strong your prescription is. The 1.57 index lens will be 15% thinner than standard 1.5 index with the same prescription. They are suitable for wearer under +/_2.00.
