All her symptoms are pointing towards severe dryness Detailed eye checkup for dryness needs to be done To rule out the cause behind Dryness in her eyes Then according to that treatment should be given Just putting eye gel and tear forming drops won’t help if basic reason behind dryness is not evaluated

Usually dryness is a long term problem. There needs to be a thorough ophthalmic and systemic evaluation to know the cause of dry eye. If topical medications are not helping, systemic medications or punctal plugging can be done.

Hi.. We need to rule out she  doesnt have any corneal condition, any minimal lens opacity or a condition called Albinism ... If all these not there , then we cant do much about it. I have seen very few patients like this who are extremely sensitive to light without any findings .. She may use Polaroid glasses with ARC coating at least in sun light. Give all vitamin supplements under doctors supervision and lubricating drops .
