Lasik still has no 100% guarantee (and your vision might still get worse by mere aging). And to me it really doesn't matter whether I'll have the hassle of 0.5-1.5 corrective lenses or my current 6's.

And yeah, multifocal lenses are a thing. Even my regular ones are weighted, and you can do the same there to achieve the same results as regular bifocal glasses. Although I know someone who just has different corrections for each eye, which sounds a bit weird to me.
