Daughter was born 24wks 6days. she is 15 days old and her eyes aren't open. when should they open? is this normal? she is in nicu. weighs 1lb 8oz.

Could be okay: 26 weeks after conception or 28 weeks of pregnancy the baby's eyes open. So give it some more time and ask your doc, too. Here is a handy article : http://www.mayoclinic.org/healthy-living/pregnancy-week-by-week/in-depth/fetal-development/art-20045997

Examination: I would suggest having all the lights off to check whether she will open her eyes. When I examine premature infants this sometimes helps during the ophthalmologic examination. With growth premature organs grow and I also advise optimizing nutrition.
