Unless you have a high prescription (e.g. more than -7.0) I'd recommend going for plain CR-39 lenses, as they have the best Abbé value, i.e. lowest chromatic aberration, of any of the plastic lenses.

But frame choice often affects the weight of the spectacles more than the lens material, so perhaps you need to revisit your frame choice.

Winning while considering setting up a spectacles advice thread....
