Welcome to Just Answer:
It appears that you are experiencing the symptoms of distorted and blurred vision due the inability of your eye muscles
to co-ordinate. The causes of Bell's Palsy are many including viral infection or other medical condition, but overall most will resolve on their own with time. Closer evaluation by your doctor will assist in determining the specific cause. The time to resolve can be weeks to months. The treatment is usually supportive, but sometimes oral prednisone to reduce the inciting inflammation or immune activation underlying the bell's palsy can help speed recovery. To help with the vision, I suggest that you follow-up with your eye doctor for closer evaluation. The continued use of tear drops and ointment is important to prevent dry cornea.
It may be necessary to patch or wear a patch cover over the affected right to prevent double or distorted vision. The symptom of flashing light on the bottom of your left eye is a little concerning, so I suggest that you follow-up with your eye doctor for good dilated eye exam to exclude any other problem with the retina at the back of the eye.
