If she has a very strong blink reflex, and they're soft lenses, then she could put them on the cornea of her eye, close her eye and move her eyeball to find the lens, as it were.
My mum could never put the lens straight over the centre of her eye, and neither could I - the optician, god love him, tried for half an hour, but I just kept closing my eye (I was 16) and in the end he gave in, told me to put it on the white bit and it would slide into place when I closed my eye and moved my eyeball around. And that's how I put my lenses in every day for 20 years.
It did mean that I could only every have soft lenses though; hard and gas-permeable lenses needed to be placed over the pupil.
Cote - both hard and gas-permeable lenses can slip out of position and need to be poked back, from watching friends with them. Soft lenses pretty much stay where they should be, unless your eyes are FILLED with rain (been there, cycling in the rain, eyes drenched, one lens swims away...)
