Don't need to use your normal eyes to see auras, just have to awaken her third eye.
But if she wants to use her physical ones try this test. If it works there should be nothing to stop her. If it doesn't, I will see what I can find for exercises to open the third eye. And eventually post a meditation for opening that chakra.
in front of a white background, hold your hands up to eye level so that the tips of your fingers is touching its match on the opposite hand (pinky to pinky, index to index, thumb to thumb etc.....) Then look directly at your fingers while you slowly pull them apart. Most people will see faint lines or discolouration running between the finger tips.

Some claim that the chakras can be opened via chakra gemstones. For the Third eye Amethyst, lapis, or
*sodolite* (if available try the sodolite first). If you don't have any of these, pm me a list of the stones you do have available.
