Welcome to HCM
It is good that you are in good health,as far as your Blood pressure is high and you are taking Amlodipne you have not mentioned strength ?,but vision problem what kind of blurred vision
It is possible with amlodipine
use but it is not common but reported in literature , may be you are developing a Cataract
in your eyes ,so go for opthalmological check up.
Other vision problems like vascular causes like thrombosis
and arterial embolism
are possible so do not ignore it ans see your Physician and Opthalmologist as soon as possible.
You can continue to take amlodipine if your BP is high.
