I suggest speaking with her optician about this option.
What can work and be beneficial for M_V might not be for her.
Unfortunately, as a healthcare professional who has worked in contact lenses for a bit in my career, I have noticed that many contact lens wearers tend to self-prescribe them with x,y,z lenses without any professional opinion/support.It is true there are lenses out there that can be worn in extended wear as M_V but normally there is someone who helps you determine if this is a healthy choice and guide you through risk&benefits.
We do have only 2 eyes (most of us) and it is better to keep them super healthy.
Nice one, she's not tried them, I'll buy her a pack for her birthday ;)
