Most of the problems I see are related to drying and irritation of the conjunctiva and cornea which results in dry, scratchy, irritable, burning, sometimes blurry eyes. I recommend artificial tears like Thera Tears as needed and if irritation or bluriness becomes more than an intermittant problem, you should call your ophthalmologist for a checkup. Permanant damage is not something I have seen, although cataract formation can sometimes be increased somewhat - just from my experience. Good Luck.
Chemotherapy does not cause blurred vision in everyone.I would recommend that you seek the care of an eyeMD if you are experiencing blurred vision.
