Inability or difficulty to see in bright light is known as photophobia. There are many causes of photophobia like migraine, eye diseases like glaucoma, aphakia, iritis, corneal ulcer and cataracts.
I would suggest you to please consult an ophthalmologist and get a complete eye exam done. Take care!
I have visited an opthamologist and been given the all clear from those tests too, that was the first step I took once these symptoms began I immediately suspected something to do with the eyes. It seems strangely coincidental that the vision problem began after my first migraine attack which affected my vision with an aura which preceded the migraine. There has to be some kind of drug out there which can at least minimise the symptoms, even that would be a blessing in itself!!
How are you?
Isoproterenol has been found to helpful in reducing the ocular symptoms of migraine.
Please discuss this with your treating doctor.
Magnesium supplements are very helpful in prophylaxis of migraine. I would suggest you to try these if possible.
