So right now I'm seeing this weird blur that kind of looks like a heat mirage thing. Its mainly my right eye and its kind of feels dark if that can be described as a feeling. Its the second time I have seen this. Last month my thyroid medication was increased from 5 to 25 and just yesterday it was decreased to 12.5 because I was having symptoms showing it was too much. My eye is also starting to feel and see a bit better after about 10 minutes.
