do u prefer contact lenses from spex

I don't have to wear glasses yet but if I ever have to wear them , I would like to try contacts only because I look like an old school teacher in glasses and have always wanted to change the color of my eyes from brown to blue . I saw a friend of mine do this and I loved the color even though it was not natural looking . This option may not be one I could have though as not everyone can wear contacts but I would try anyway .
