I must add, that it would be very wise to see a Dr. regarding your eyes.
Good luck!
sudhamaa,
Unique has had this problem "for sometime now".
While your statements are very true, they do not pertain to him.
I am not a doctor, and I could not understand your problem also. But I am only suggesting from personal experience. When there was a similar problem of sudden blurred vision, we were suggested to (a) see an opthalmologist immediately, and test our thyroid level in blood; (b) test our blood sugar level; (c) go for investigation by a neurologist (d) do ct scan of the head, carotid artery duplex scan and cardiovascular examination. We were told not to delay.
I just had cataract surgery 2 days ago. Painless & successful, and it's amazing how well I see.
I saw my retina specialist was June and it was not detected then, but only during my last visit 1 week ago.
I had a cataract and didn't know it....this may be true in your case.
I assume any Ophthalmologist can detect a cataract.
Hope this helps!
