Suggest Treatment For Dark Spots In The Field Of Vision Caused By Metoprolol

I found out that one of the side affects of metoprolol is seeing auras around lights. I am 51 years old. I have been taking 25 mg for a few years now. The auras are really bothering me especially when it rains. I thought it might be cataracts but the eye specialist said they are not bad enough to be bothering me.
