So few months ago my optician gave me to try for first time soft contact lenses. She opened them in front of me. Unfortunately I couldn't see the brand, I've moved out from the city and lost the phone number. I wanna know what brand we're those contact lenses, so here's what I know:

-I'm nearsighted with -3 pwr, I know she didn't give me toric ones
-She told me I can wear them continously, even when sleeping, for 30 days
-They had an inside mark with the letter "E"
-They we're quite rigid, you couldn't flip them over easily

Also, what do you prefer Biofinity or Air Optix Night & Day ?
