Safe contact lens advice/brands??

Hello! So, i never wore cosplay contacts in my life. I do know a few things about them, like how you cannot use certain lash glues after applying them & such.

Im going to a con next month, & im looking for some natural brown circle lens that can make my eyes a bit bigger and doll-like. I just need some good brands to use & how to use them!

Also if anyone wants to share methods to remove and apply them thatll be awesome!! Im scared of my contacts shifting.. i do wear prescription glasses btw! Will it look any different?
