Dear Gordon76,
I would recommend that you take your daughter to an eyeMD and determine the cause of her light sensitivity and what issues she might have. She should see and eyeMD specializing in retina due to her prematurity.

There are a few causes of your daughter's problem. Take her to an ophthalmologist.
