It actually does matter. Colored contacts are a fun choice. I used to wear them. But they will dry out your eyes and may irritate them. I would recommend getting both colored and non colored contacts. That's what I did and I wore them when I went out but changes them when I got home cause they were slightly irritating... Like wearing a pair of heals and then bringing those fold up slippers when your feet get tired.
If you dont wear glasses why get prescription contacts get the color contacts without the perscription so ur not messing up ur eyes and if u do get contacts if ur eyes are dark go for the expression color contacts there made for dark eyes or a light color so u can see them and so they dont blend in and so u can see them same for if u have light eyes originally go for the dark colored contacts
