Are Efika Smartbook screens too bright?

I have a light sensitivity which gives me trouble with many newer computers. (For example, I cannot use newer Toshiba models because, even at the dimmest setting, their screens are too bright for me to look at without eye pain.)

I would like to know whether the Efika MX Smartbook has screen brightness controls, and whether the controls allow users to dim the screens enough.

Thanks.
