I just asked my eye doctor about this yesterday. She said LASIK would correct myopia for 10-15 years, then it’ll start coming back. She also said everyone loses up close eyesight about 45 so you’ll have to wear glasses or contacts anyway. Said it’s only worth it if you really want to see without putting on glasses.
I have some friends that love them and only have purple mattresses now. I slept on their bed and it was okay… I think if you prefer the floating on top feeling they’re probably great, I prefer the tempurpedic style of sinking in
