Thanks for posting your query at DoctorSpring.com
I can understand your concern.
I understand that you are away from a doctor and it's difficult for you to visit a doctor. Sensitivity to light which is known as photophobia usually occurs before the rash shows up. But it can also occur in cases where there is severe inflammation present inside the eye as a complication of chicken pox.
Hence i would still recommend that you visit the emergency room and let them examine your eye at the earliest. Its best not to wait for it to get so severe that there is a major complication.
Please let me know if you have any queries.
