Can I upgrade a 1.5 index lens to 1.7 index lens without replacing the lenses?

I just bought standard 1.5 index lens but I think they are a little thick for me. I wonder if I can make it thinner by upgrade it to 1.7 index without replacing the lenses?

    There is no way to make the lens thinner without replacing the lens. The index is determined by the type of plastic material used to make the lens. Just think of changing your sweater from cotton to wool without getting a new sweater. Of course it is impossible.

    That's impossible. The only thing you can do is to replace the lenses if you want to upgrade a 1.5 Index Lens To 1.7 Index Lens.
