It is an oportunity to practice and once she gains a bit of confidence in her shooting ability she will feel more comfortable with the situation. This is not a significant problem and frankly it's better to shoot with both eyes open. She might also want to get her eyes checked to make sure she has good vision in each or at least get them to match. Having differnt focus points between the eyes can make it hard to focus on the sights and or the target.
Ya that was my first thought.... maybe her left eye is dominant.
To find your dominant eye....while not fool proof, this works pretty well...
Find a small object to focus on like a light switch.
Then hold your arms out straight...while holding your hands up, and palms out, place them in front of the 'light switch'. Overlap your thumbs make a very small 'triangle' with your thumbs and palms.
Move you head around and search for the light switch keeping your hands stable.
When you focus on the light switch inside the triangle you made with your hands,. . .
Close one eye if you can still see the light switch, your open eye is your dominant eye. If you can
not see the light switch ... the eye you closed is your dominant eye.
