I very quickly located some sites that list blurred vision
as a possible side effect or Norvasc, or Amlodipine. I'm
sure I could find more, but one of them, from the very
reputable site of the Mayo Clinic had a note of urgency
to it, so I wanted to post this as soon as possible:
"Symptoms of overdose
Get emergency help immediately if any of the following
symptoms of overdose occur:
Blurred vision; confusion; dizziness, faintness, or
lightheadedness when getting up from a lying or sitting
position suddenly; flushing; sweating; unusual tiredness
or weakness."
http://www.mayoclinic.com/health/drug-information/DR500563
This page from healthsquare.com lists double vision or
vision problems as a rare side effect:
http://www.healthsquare.com/newrx/nor1306.htm
This page from the American Optometric Association has a
"Quick Reference to Ocular Manifestations of Commonly
Prescribed Systemic Medications"
For hypertension, it lists the following drugs:
furosemide (Lasix)
hydralazine hydrochloride (Apresoline)
enalapril maleate (Vasotec)
captopril (Capoten)
nifedipine (Adalat, Procardia)
triamterene (Diazide)
lisinopril (Zestril)
amlodipine (Norvasc)
For which it lists these potential optical side effects:
"Blurred vision, conjunctivitis, photosensitivity, visual
hallucinations, tearing, nystagmus, retinal hemorrhages"
http://www.aoa.org/x1928.xml
This page from the Pharmacogenetics And Pharmacogenomics
Knowledge Base also notes blurred vision as a rare side
effect of the drug, along with other syndromes, which may
produce the following symptoms:
"hypotension
(blurred vision; confusion; dizziness, faintness,
or lightheadedness when getting up from a lying or sitting
position suddenly; sweating; unusual tiredness or weakness)
peripheral vasodilation
(flushing)
reflex tachycardia
(fast or irregular heartbeat)"

I would suggest looking closely at the symptoms, aside from
blurred vision, that accompany hypotension. If you have any
of them, it may be that your blood pressure is coming down
too far, and it can then drop rapidly when you get up from
sitting, causing dizziness at the time. If you blood pressure
is consistently too low, it could certainly affect your vision.
Obviously, this means a visit to the doctor so he can check
your blood pressure. Let him know what other symptoms you're
having, especially if you see them on the pages I've referred
you to.
