My older child wants LASIK? LASEK? surgery.

They say many friends have done it, and they also want to undergo LASIK surgery or wear Dream Lenses.

Is it possible for a minor (such as for school-related issues) to undergo surgery?

When would be the most appropriate time to do it?

Is it better to do it when you're young? Or is it better to do it after becoming an adult? Since you'll also be going to the military, it would be better to have good eyesight rather than just wearing glasses, right?

Is it necessary to wear dream lenses when you're young? Will dream lenses be ineffective if you're over 20 years old?

The child wanted to try wearing contact lenses again, so I attempted several times but ultimately couldn't put them on and failed (I ended up wasting three pairs of lensesㅠ). Should I give up on Dream Lenses?
