The name is Joe. I have a wife who is experiencing vision loss in her left eye. She was diagnosed with brown syndrome in her left eye and recently she has been saying that her left is worse than her right and it feels like something is in it. As if she feels something under her eyelid or on her eyeball.
She was supposed to wear her glasses at all times and she hasn't worn them since 2010 because they would always give her a headache. But the past few days she says it feels like it's getting fuzzier in her left eye.
Thanks for your Question
Brown syndrome doesn't cause blurred vision, it causes abnormal ocular movement and double vision.
Foreign Body sensation might be caused by dry eyes. Dry eyes also cause blurry vision so try to use lubricant eye drops and in case no improvement in her condition, you should visit your eye doctor.
