My daughter has been telling me her eyes keep seeing colored spots and they feel heavy . she says it bothers her to look at her phone and watch t.v. she has headaches sometimes but no while this is happening?

Her age? : Many explanations. If she has periods, then migraine is a common cause. Many other things could cause these symptoms. Please have her doctor take a look and get a proper examination and treatment.

? Migraine headache: Your description sounds like a migraine headache but other issues could cause similar symptoms. Go see an eye doctor.
